Have read Rover 75 threads on this subject and note that shorting pins 4 and 8 on the diagnostic socket is said to reset the indicator. Checking the wiring diagrams, pin 4 is earth, pin 8 goes to the instrument pack (skt c0233 pin 5) and ABS ECU (skt c0501 pin 11). Although this method was suggested in the threads, nobody appears to have reported success (one or two said it did nothing!). Can anyone supply confirmation before I take this - possibly risky - step?

The success rate seems to be about 50/50. Might be dependant on year/model ?

If at all in doubt, don't risk it !

Your local garage may have service reset tools, they'll probably only charge you a fiver for the reset :)

I tried it for the first time this last weekend.
My 75 is a jan 2004 '53 reg, just pre face-lift.

An update on this and related threads - Have just had the 75 serviced at Nationwide Autocentres ( nice job btw) but they couldn't reset the service interval countdown . So , I decided to have a go at terminals 8 and 4 with a carefully crafted piece of bent wire - It worked first time ! For the record , this was on a 51 reg 2L v6 conn ; the countdown interval only appears briefly so i inserted one end of the high tech bent wire into pin 8 and as soon as the service figure appeared I just flashed the other end onto pin4 - no more than a second . The countdown reset to 15000 , and everything else has been working ok since yesterday , so I'll be doing this again . Please note ,like someone else said , this worked for me on my model but i dont know if they are all the same so we all do this at our own risk !

Took the plunge and earthed pin 8 while service indicator was showing. Seemed to need a couple of seconds contact. Anyway, back to 15000 now! That's on a 75 Tourer diesel Jan 02.

My 75 is having it's 60,000/4 Year Service on Monday so I shall be trying this reset trick too.

Am I correct in thinking that I simply insert a wire into hole 8 and hole 4 at the same time ?

Also my Service Indicator is currently showing -2800, has it gone too far to be reset ?

Dr Dave
21-05-2005, 20:31
Nope, it'll still reset OK..

IT WORKED !

The trick is to insert a piece of wire into hole 4 before turning the igintion to position 2 and then quickly insert the other end of the wire into hole 8 as soon as you have turned the ignition to position 2.

I'm now back at 'OIL SERVICE 15,000' and the car is only being serviced tomorrow :lol:

Owner of a 75 CDT Auto showing -1400. Worked fine after 5 or 6 goes. Tried it then on a friends 75 CDT manual with -2100 serval times . As yet no joy. It does seem as if timing is everthing. It would help if I knew which pin first and for how long. I used the pin 4 first then pin 8 and it worked eventually but as I say has yet to work on my friends.

Pleased to say shorting pin 4 and 8 after switching ignition to second position worked fine for me too. Rover 75 1.8 - Mar03 - 03 reg (pre-reg and stored with 1 mile on the clock for a year - I bought from Virgin Cars). I had about 400 miles to go to the service due. This was the first service and the 'oil service' that had been counting to the 'Oil Service' due had now changed to Inspection Service due. Thanks for the great website.

RichK
24-05-2005, 19:32
It won't make the slightest bit of difference which pin you connect first as you're just shorting the two pins together.

I've found a paper clip works best, fits snugly :)

You need a magnifying glass to see the numbering + body contortions to see the socket at a reasonable angle! Althenatively, look at a previous posting set on this subject where a diagram of the socket was shown. As I mentioned in my original posting, pin 4 is only an earth connection - so you can short pin 8 with a length of wire either to pin 4 or any bare metal.

Silly question.


Couldn't you put your pin in hole 4, and then runa wire to the body?? Then you wouldn't ahve to faff with getting the pin in th'other hole ;)

You have to short the Instrument Pack pin to GND for differing times depending on what type of service you are resetting. And yes, it works on all models.

Type of Service Time for Short to GND
Oil Service 1 4 sec
Insp. 8 25 sec
Oil Service and Inspection 8 25 sec for Oil & Insp.
Time interval 8 25 sec
Oil Service and Time interval 1 4 sec for Oil Service then 8 25 sec for Time
Insp. and Time interval 8 25 sec for Insp. then 8 25 sec for Time
Oil service, Insp. and Time interval 8 25 sec Oil & Insp. then 8 25 sec for Time

Been bugging me for ages, bought the car from a non-rover dealer who serviced it and never reset it. Thought I was going to have topay for another service just to get rid of light.

...all fine once I'd found pin 8 (***)

It may be a coincidence that your clock has stopped, however if you check your manual you'll be able to identify the fuse for the clock and it's a simple job to replace.

Adendum:
After a service is completed, the instrument pack service interval display has to be reset so that the countdown to the next service interval can begin. If the display is not reset and the distance indicator reaches zero, a negative distance will be shown on the display, inferring an overdue service. Resetting the service interval display, resets the distance countdown back at 15,000 miles (24,150 km).The service interval can only be reset within range of the service interval (e.g. 1000 miles).
Ideally, the service interval should be reset using 'Testbook' connected to the diagnostics socket. In the absence of 'Testbook', the service interval display can also be rest by shorting the DS-2 diagnostics bus to ground for a defined period, while the ignition switch is in position 'II'.

l If an oil service has been conducted, then the 'Oil service reset' must be used, so that an 'inspection service' is indicated for the next service interval.

l If an inspection service has been conducted, the 'Inspection reset' command must be used so that the next service indicator is for an oil service.

l If an 'oil service' and an 'inspection reset' is required, then these must be reset using the 'inspection reset' command.

l If either oil or inspection is required, and a 'time service' is also required, then the oil / inspection reset should be done first, followed by the time reset.

l The 'Time service' is reset by using the time service reset command.

The times required for shorting the DS-2 pin to ground to reset different types of service interval indicators are listed in the following table:

NOTE: The service interval can only be reset to within the range of the service interval (e.g. 1000 miles /1600 km).
NOTE: It will only increment every 40 miles (50 km)

You have to short the Instrument Pack pin to GND for differing times depending on what type of service you are resetting. And yes, it works on all models.

Type of Service Time for Short to GND
Oil Service 1 4 sec
Insp. 8 25 sec
Oil Service and Inspection 8 25 sec for Oil & Insp.
Time interval 8 25 sec
Oil Service and Time interval 1 4 sec for Oil Service then 8 25 sec for Time
Insp. and Time interval 8 25 sec for Insp. then 8 25 sec for Time
Oil service, Insp. and Time interval 8 25 sec Oil & Insp. then 8 25 sec for Time

It is just a toggle action - think of it like a seesaw one, or the other, or one and the other - until you get the right combination - personnaly I travel 15000ml/25000km a year so every official service is an oil service, but then I also change the oil every 6mts 7500ml/12000km myself - I'd rather spend $60AUD/25GBP for a full synthetic oil as well -- call me cautious.

just did the wire from pin 4 to pin 8 and it worked fine on my uncles car, which is a rover 75 cdt con Y reg 2001.

at least i think it worked fine, after doing it, it came up to 15000 inspection on the dash. Is this correct, has it worked properly?

It took a few goes but I've reset mine - KV6 2 litre auto, 2000 on a W. Paperclip is definitely best, but you need to push it right in to get a connection.

Quick fiddle with the drivers seat pad sensor underneath while I was at it, now no more warning lights!

Works for a lhd 2000 diesel 75 as well. I was 500 km past the oil service and had it changed locally. Only afterwards did the bloke tell me he couldn't reset the thingy. It now reads 24500 to the next main service.

BTW you seem to be able to see which pins can be used and which not by if silver metal is visible or not. Since the steering wheel is on the wrong side I was worried that I had a mirror image or something but as far as I could see there was only one that could be 4 and another 8 because the others were just black plastic.

"The service interval can only be reset within range of the service interval (e.g. 1000 miles)."


does this mean if you go 1000 miles past the interval this method will not work ? or am i reading it wrong (the 75 i have just bought indicates its 7000 past service althought has been serviced at a garage who did not do a reset)

Can anyone supply confirmation before I take this - possibly risky - step?

I tried it today and it definately works. I have a 2 year old 2.5 Rover 75. The Diognostic socket is by the drivers right knee, under the dash, it is in full view, no need to siturb any trim. Pin 8 is bottom left pin, pin 4 is 4th pin from the right. I used two paper clips, one straight, one with an angle. Turn the ignition to step 2 and touch the two paper clips together for about 20secs. Turn off the ignition and then turn it on again. The reading should read 'Oil Service 15,000'

RichK
03-10-2005, 23:13
magy - it means you must do over 1000 miles from the last reset point, before you can reset it again.

As you say, valuable stuff. I'm putting together a dossier of Know-Hows for when my warranty expires. ATM I have to pay very high servicing charges to guarrantee my Rover warranty, but will revert to DIY after that.

I've studied all the posts in this thread and now hopefully understand how the resets are done. I wonder if I sussed why some people haven't got it to work when others have. Logically all Rover 75 models work the same in this, so it must be the way it's done that's important. Anyway, I'd be grateful if someone who really understands it will check through my notes? Here's what I've got so far.

The trick is to insert a length of insulated electric wire into connector 8 of the diagnostics socket and to earth the other end immediately after turning the ignition key to position 2. As the earthing takes place, begin counting the seconds as appropriate, then break the earth link. Aim for around mid-time range so you don't need stopwatch accuracy. Using a long wire means you don't have to fiddle with two connectors in the socket. Just hold the wire and earth it precisely.

You must earth the wire for differing time periods depending on what type of service/services you are resetting. There may be just one time session or it may require two sessions in turn.

If an Oil Service has occurred, use the Oil Service reset, then turn off the ignition. Next startup, an Inspection Service 15000 will be displayed as the next service interval. An Oil Service reset lasts 1 - 4 seconds.

If an Inspection Service has occurred, the Inspection reset is needed to bring up the Oil Service display at the next startup. Inspection reset lasts 8 - 25 seconds.

A Time Service reset also lasts 8 - 25 secs.

If an Oil Service reset and an Inspection reset are required, run an Inspection reset only. So, an Oil + Inspection reset is 8 - 25 secs.

If Oil or Inspection, together with a Time reset is needed, do the Oil/Inspection first (1 - 4 secs or 8 - 25 secs) followed by a Time reset of 8 - 25 secs. Do not move the ignition key between the two resets.

If you get any timing wrong it probably won't work. A wrong timing would be between 4 and 8 seconds, more than 25 secs or less than 1 second since none corresponds to a reset time period. I guess it uses a simple counting method.

A service display can only be reset when the 'excess' mileage is 1,000 or more (?) - Or is it - A service display can only be reset when there's been 1,000 or more miles since the previous reset.

(I don't understand either of these. Can anybody explain?)

That's it so far. Sorry if this seems pedantic, but in two years time, I'll need to go through all this again and I want to be sure.

Cheers,

JaX

RichK
15-10-2005, 20:11
You can only reset it once 1000 miles are showing on the service clock, regardless of the actual miles you have driven since the last reset. The countdown is based on your driving style, road types used, mpg and other factors so it's possible to drive over 1500 miles yet still only show 14000 to the next service.

If the service indicator says 14025 miles to the next service, you will not be able to reset it until it says 14000 miles (or lower).

Hope this is a bit clearer :)

Hello RichK,

1. Does the reasoning in my post above explain why people haven't got it to work?

2. OK thanks, I think I understand. Anyway, I'll keep reading it till I do. Does it imply you should use your odometer mileage for servicing rather than the countdown readout 'cos I can't see any other reason why you would want to do it? If that's so, why bother to have the countdown system?

It also explains why my countdown reading doesn't seem to move down much. I wondered about that. Guess I'm a leisurely/luxury rather than the speedy/flashy type!

Cheers,

JaX

Hi Jax.

1. Sure does. It's all in the timing!

2. Never use the odometer mileage, the service counter is designed very accurately, as per my previous post.

Double check the connector were you insert the wire. It should go *well* into No.8. If you are sure about that, make sure the timing for grounding it is done correctly. Read my previous post on this, I wanted to make sure I understood it right and seems I do.

Another point on this issue. The RAVE CD-ROM has an error in one of the diagrams of socket C0040.

In the Connectors listing, C0040 has the pinouts exactly as discussed in this thread, with Nos. 1 and 9 at the right hand end of the socket. However, under Rover 75/Communications and Data Buses/Description/Diagnostic Bus, socket C0040 is drawn with Nos. 8 and 9 at the same end.

So much for the RAVE CD! Is it known to have errors or is this likely a one off?

As I understand it, negative values reset just like positive ones. Your problem must be in the timing used for the reset.

19-10-2005, 20:20
Going through the timings again, I'm now confused about what has been called an 'Oil Service PLUS an Inspection Service' reset.

My 2004 handbook says three conditions may be displayed.

Oil Service, or Inspection and there maybe a Clock logo (Brake Fluid change). I assume the Clock is a 'Time Service'. Is that correct?

How can you have an Oil Service AND an Inspection displayed together? Is the pre-2004 display different?

Cheers,

JaX

Confirmed.

You can reset ANY negative value at any time.

WaveGuide
20-10-2005, 20:05
I'm still confused about resetting an Oil Service WITH an Inspection Service because they alternate every 15,000 miles.

Surely you can't see both on the display at the same time?

I understand that each has the same 8-25 second reset, but my 2004 handbook says only four displays are possible.

Oil Service + Clock sign
Inspection + Clock sign

Well, I had a inspection sitting at 6275 and done the rest thing and now the Oil Service is sitting at 15000, I left the bit of wire in for a full 30secs or so......and mine is a R75 2.0V6 Classic on an 2000 (X), Just done a service on it about 1 month ago, and oil service 3 weeks ago, so superb bit of techy knowledge.

Finally it worked for a 2002 2.0CDT.

I have spent the last couple of days trying this and gave up many-a-time. The suggestion to use two paper clips (one straight and one bent) worked eventually. Keep trying, I must have tried 30 times or so with differing combinations. Try adjusting the depth in which the clips are pushed into the connector. Have both in place but not connected, as soon as the ignition is in position 2 and the service interval comes up, connect the two clips and hold for 10secs, then turn off ignition. Good luck!

Took me quite a few attempts to get it done. I wasn't sure if I could short pins 8 and 4 before turning the key or not. In the end it worked by shorting pins 4 and 8 only when the service indicator was displayed. Next time, I'll be due for an inspection - well the car that is.

Thanks for all the tips guys.

buy a metre of 1.5 twin and earth from hardware shop, strip back outer insulation about 3 inches at each end,pull out earth wire (the one with no insulation) strip back insulation about half an inch on the four remaining wires,fit a cheap bell push to one end ,the two wires at the other end will fit snugly into socket. Switch on ignition position 2 press bell button 8 to 20 seconds Bingo .Cost about 2 and you get to sit while you do it.

I used a paper clip too - just the right diameter to go in the hole. I just used the one clip in pin (hole??) 8 and shorted to earth (the door retaining strap) with another wire. To amplify previous posts, the ignition should be on position II. Shorted No.8 to earth for the required time, but the indicator didn't reset until I had switched off the ignition, and switched on again. For anyone still unsure which pin to use, No. 8 is the one closest to the pedals and nearest the centre of the car. (2004 Conn. SE CDTi)

Hi all,
Just to add to the stats, my 75 is a 1999 2.5 V6 and the procedure worked fine with no apparant side effects. Don't forget though, the RAVE CD says the indicator can only be reset if its within (in my case) 1000km of the service. Maybe this is why some people are experiencing problems?

any-mgzt
15-01-2006, 11:01
As I stated it took me a few attempts but it worked, my car is a late 2001 2.5 MG-ZT 160?? and the service indicator was reading -1500 mls.

I say 160?? because the VIN Number according to the chart in the 75 / ZT forum the engine type for my car is not listed as a 160?

Anyone can help then my VIN is SARRJXLEF2D******

25-01-2006, 01:49
I bought the little module from the guy from Ebay and it worked perfectly first time. I know it cost 5 when a paperclip would cost a fraction of this, but it really was dead easy and there was no scope for me to get it wrong.

For the record
Worked first time on '04 R75 Conn., bog standard (Face lift) model.
Inserted paper clips first (both bent) thus able to easily reach with the door closed, set ignition to P2, then shorted. After a few seconds I noticed the display blink, then removed the short. After switching back on, the display showed Inspection and 15000ml.
The reading before I reset was -5260.

Looking for some advice I hit on this forum and am well impressed. I have just had an oil service and was wondering what to do about the service indicator. Found the relevant Technical Information Document so thought I'd give it a go. Put a paperclip in pin 8 of the socket and used a crocodile lead to short it to the door stay. IT WORKED FIRST GO!!!

Rogerborg
05-03-2006, 12:37
It took me quite a few tries though. It didn't work with the pins pre-shorted before turning the ignition to position 2 (it's not supposed to!), or when I took more than a fraction of a second to short them. You have to be pretty quick.

I should have read to the end of this thread; it only occurred to me afterwards that it really is smarter to insert wires or paperclip probes into both pins 4 and 8 first, then short the exposed wires or pins, rather than trying to insert things quickly after turning on the ignition.

sparrish
11-03-2006, 12:52
Have read Rover 75 threads on this subject and note that shorting pins 4 and 8 on the diagnostic socket is said to reset the indicator. Checking the wiring diagrams, pin 4 is earth, pin 8 goes to the instrument pack (skt c0233 pin 5) and ABS ECU (skt c0501 pin 11). Although this method was suggested in the threads, nobody appears to have reported success (one or two said it did nothing!). Can anyone supply confirmation before I take this - possibly risky - step?
I have a Rover 75connoisseur CDT Touring estate on an 02 plate and have just reset the service back to 15000 it was on -3450.
Put a paper clip in hole 4 from right to left, then turn on ignition and while service interval is still up push the other end of paper clip in hole 8 far left for 2 seconds.
Pull out wire turn off ignition and then turn back on it should say 15000.
Well done if it works first time as it took 3 atempts for me to get it to work.

i have just purchased an 05 (54 plate) Conn CDTi, and my millage reads just over 19,000 but on start up it's reading -9600 or something, does this mean it's gone over it's interval, i find it hard to believe having only done 19,000 miles unless that is, someone one has already tried reseting trick.
So is the - figure an indication that its gone over?

Hi all

I've read a lot of the threads on the reseting of the indicator and they all seem to talk abot 2 banks of pins 1 - 8 and 9 - 16, I must be missing the point because on my 02 plate 1.8 75 club I can only find one bank of pins under the right of the steering column and not all of those seem to be populated with connections. do I assume that the one bank of pins is 1 to 8 ans still earth out pin 8?

hi guys

this weekend i have just done an oil and filter change on my zt V6.
However when it came to resetting the service indicator it would not reset back to 15k miles.

since last year i have only done 3k miles and the service indicator is showing 12.4k miles at present.

It is just over a year since i last serviced it and was able to reset it back no problem for the oil service the first time - my resetting tool is a proper MG/ROVER /CARTOOL one so i don't understanding why it hasn't worked this time.
Does it need to reach a certain mileage before it will reset for the inspection maybe ?

your help is much appreciated.

I have reset my service indicator twice now.
When I first got the car (2 years ago) it was on -30,000 on the indicator. I reset this back to 15,000. I tried to reset this to longer 8-10 second reset but nothing happened. Then I read that you have to wait 1,000 until trying to rest back to 15,000 so I waited (baring in mind that I only travel about 3,000 miles a year!) I had to wait a while. But after the 1,000 miles had been traveled it worked again so now back to 15,000. and with a full service history (not main dealers but all stamped). :happy:

My Rover is 75 2000/W 1.8 Classic SE White Gold.

Thanks it worked for me. 2004 pre facelift model 1.8t.

it took me a few go's at it.

The trick is to short terminal 8 just at the same time as "inspection" comes up on the dash.
2 people is best as it is fiddly doing it on your own.

one to turn on the ignition and the other to connect to terminal 8 at the same time.

good old paper clip and torch is all you need.

frirl
05-01-2007, 18:23
no mechanical or electronic implications that I know of. However, the countdown does not work in parallel with odometer, ithe ECU assesses the type of driving being done, ie stop/start, long-haul, speeds etc., and so, may reach zero, before 15,000 are travelled, or long after (in the case of long motorway gentle driving). So my handbook suggests!

Not sure if anybody else has spotted this earlier but just tried to reset using pin 4 & 8 and it didnt work. Undid the two facia panel screws and pulled the plug holder down, the plug had been put into the holder upside down! Maybe my CDT had been built on a monday morning? spotted the numbers with a magnifying glass and torch - should become a contortionist! put the wires in and bingo! it reset straight away.

Superb info and thanks to everyone. I bought a new 1.8 facelift model on the '05 plate the Saturday before Rover went bust!! I had a service carried out at a local and trusted garage who assured me the service counter would be reset no problem. After 4 attempts it was still showing the service as overdue. The car has been driven for around 4 months without the counter reset. I found this info last night and couldn't wait till daylight. I went outside with a torch and the job was complete within 3 mins. EASY! I simply stripped two wires approx 10 inches both ends and put 1 end in pin 4 and the other in pin 8. I then switched on the ignition to the second position [ON] and shorted the two ends of the wires for about 6 seconds. Having longer wires makes life much easier than a paper clip, though the clip does the same job electrically. I agree with previous posts and the timing and duration may be key to the reset. It worked for me on the second attempt. Thanks again to everyone. I am now off to buy an Audi A6 and take my money whilst I can. I did enjoy the Rover but times must move on.

Just reset my ZT 190+ (03 plate). Worked 1st time with no side effects. Many thanks guys.
Oh yeah, just thought I would add that my service indicator was showing -6075 miles. Now at 15000. Reset no problem. Thanks again

You have to short the Instrument Pack pin to GND for differing times depending on what type of service you are resetting. And yes, it works on all models.

Type of Service Time for Short to GND
Oil Service 1 4 sec
Insp. 8 25 sec
Oil Service and Inspection 8 25 sec for Oil & Insp.
Time interval 8 25 sec
Oil Service and Time interval 1 4 sec for Oil Service then 8 25 sec for Time
Insp. and Time interval 8 25 sec for Insp. then 8 25 sec for Time
Oil service, Insp. and Time interval 8 25 sec Oil & Insp. then 8 25 sec for Time

I currently have the clock symbol and 'Inspection 10250' showing, which as I understand it means that I'm ok for a while on the Inspection service, but I need to change the brake fluid (hence the clock symbol).
If this is the case then, how will I manage to reset the time interval without putting my Inspection interval back to 15000, because according to the timings it does the Inspection before it does the time....or am I completely misreading it???:confused:

Just reset mine too, was -3300 Miles on a 51 conni Diesel, well pleased. What I did though was got 400mm of Aerial/coaxial cable and stripped each end to around 25mm and earthed one end to the door, as Per a Diagram in PDF I was kindly sent some time ago. If anyone would like it, drop me a line to biguglydog@gmail.com and i'll pop it over to you :D

I had the clock symbol and Inspection. When I reset the clock symbol went out first, I had to wait a few days until the counter had gone below 1000 miles before the Inspection reset to Oil Inspection 15000

Many thanks Cannonball, I'll give the reset a try once I've had the oil change done (and boy do I need it - the oil looks like raw crude straight from the ground!:shake: ) If the Inspection countdown resets as well, I'll just make sure I bear in mind to get it done a little sooner than it recommends.:broon:

Well I must be useless and very thick!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !

Tried over and over and over again, not doing anything at all!

Speaker cable, in pin 8 about an inch and a half and in pin 4 the same, then the other end of speaker wire touched together as I turn the switch to second position. Hold and count a slow four, turn ignition off, back on, no change at all!

Tried for 20 seconds no change.

Tried disconnecting the wires before turning ignition off, no change.

Tried disconnecting the wires after truning ignition off, no change.

I've just managed it at the first attempt, thanks to all the posts.
It was showing -30612 inspection and time.
I shorted the pins out for 20 seconds then released them, then shorted them again for another 20 seconds WITHOUT turning the ignition off in between.
You can't see the service reminder after the first couple of seconds, just the odometer reading, but keep going it does work.
I used a paperclip to short the pins but I broke the clip in half and then inserted each half into the appropriate pins, they stay there quite nicely. It then becomes an easy single-handed job to switch the ignition on and then hold the two ends of the broken paperclip together for the required amount of time, but don't forget to open them again if you need to as they may just stay together.

Hello everyone,

I would like to let everyone know that the 4 and 8 pin reset worked today on my MG ZT CDTi '55' plate.

I made a tool consisting of two lengths of wire a cheap door bell switch and two fork connectors from Halfords electrical section, removed a leg from each of the connectors, remaining leg inserts perfectly into the socket.

The reset worked first time, now at 15,000 miles to inspection service.

I have found some useful info on this forum.

Great work guys.:cool:

Just to let everyone know this reset method worked on my 04 ZT-T. For the people having problems I found you had to get the wires in place, turn on ignition and then touch the wires together.

Cheers

Sorry to bring up such an old thread.

Sounds all very straightforward, but just one thing: how long do I keep the connections shorted so the display indicates that the next service due is the 3yr/45K mile one (don't get the difference between the oil service, inspection, oil service & inspection thing - even tried comparing these to the service schedule, no joy!)?

This worked fine on my W Reg 2.0 CDT Club SE! Thanks to everyone who explained how to do it. I was a little apprehensive at first, but it only took 2 mins with a couple of paper clip. The car is very pleased - first time it's been reset in 4 years!

I write you from Italy and just wanted you to know it worked also on my ZT-T CDTi year 2005: I used one of the four couples of a piece of LAN wire and I kept the short-circuit twice for 20 seconds (so I got a total reset).

Thanks for the instructions !!!

Just done my rover 75 conn se 2001, Found it best to use the paper clips i reset all the service intervals, The trick is to touch the paper clips together after you have switiched the key to position 2 and then count slowly to 30 then release the paper clips and with the igition still on touch the paper clips together again for a long count up to 30 then switich the igition off then on again and you should see that the dispaly has changed to inspection 15000 , I think also it does not matter have many miles past the service intervals it has to be before you reset it mine was -43000.

I had to give it a couple of goes before it reset so keep on trying

good luck

Worked here!

2 secs on an 03 plate 2.5 V6 Connoisseur (2900 ahead of time as had the car serviced when we bought it - will probably reset again in 2500 miles so that it brings the service back in line for the next one)

I used 1 paper clip (straightened it out enough to slot into both holes. Removed from hole 8, turned ignition to 2 and put end back in 8. Once display had gone to normal mileage display, turned off ignition and removed clip. Turned ignition back on - done)

all the best

Just done the pin 4 & 8 on my W reg 75 2.0 V6. Clock was reading -10k and it worked after I got the paper clips in the right place.
For those of you who are still having trouble - I found that I was placing the paper clips above the silver spade connector. I then placed them below the spade connectors and it worked perfectly.

Many thanks for the advice.

Have read Rover 75 threads on this subject and note that shorting pins 4 and 8 on the diagnostic socket is said to reset the indicator. Checking the wiring diagrams, pin 4 is earth, pin 8 goes to the instrument pack (skt c0233 pin 5) and ABS ECU (skt c0501 pin 11). Although this method was suggested in the threads, nobody appears to have reported success (one or two said it did nothing!). Can anyone supply confirmation before I take this - possibly risky - step?
Hi all I bought a light reset tool on ebay for 25 +p&p it has 3 buttons to reset mileage, oil / service and days left .takes the guess work out and works perfectly. sold as R75/bmw/mini service reset tool.

electric current can't tell which way you've connected it...
another piece of info you might be interested in, when resetting these indicators with the hand-held rover tool, they will not re-set if it is not close to being due. ie. if you only do 2k miles in a year, the hand held won't work, has to be done with t4...

What a tremendous thread!!!!

I've just used the two paperclip method to reset my service mileage on my ZT 190+ '52 plate. It didn't work just touching the contacts on the connector, i had to push the end of the paperclip inside the plug, pins 4 and 8, for about 10 seconds, worked like a dream!

However, can anyone shed any light on why it used to say Inspection and now it says Oil Service????

Cheers.

Hi Graeme

With the Rover 75 and MG ZT, they work on a minor and major service type intervals. The Minor Service is the Oil Service and the Major Service is the Inspection.

So it will rotate, Oil Service then Inspection Service, then Oil Service and so on.

Hope this helps.

You have to short the Instrument Pack pin to GND for differing times depending on what type of service you are resetting. And yes, it works on all models.

Type of Service Time for Short to GND
Oil Service 1 4 sec
Insp. 8 25 sec
Oil Service and Inspection 8 25 sec for Oil & Insp.
Time interval 8 25 sec
Oil Service and Time interval 1 4 sec for Oil Service then 8 25 sec for Time
Insp. and Time interval 8 25 sec for Insp. then 8 25 sec for Time
Oil service, Insp. and Time interval 8 25 sec Oil & Insp. then 8 25 sec for TimeWonderful - thank you for that! :D

Seems straight forward. My oil change is due in 650miles and I noticed a clock symbol in the 4 second display when starting the car. What does the clock symbol indicate? Oil Change is indicated so I know what to do with that. I seem to have seen somewhere that it is for break fluid.

There are 2 rows of 8 pins . The bottom row is 1 to 8 from right to left . The Rave cd shows it under electrical connectors , #C0040 , although the photo is on a LHD auto !

Please clarify - is the row containing pins 8-------1 furthest ie back or nearest to you. As its positioned upside down and not vertical I'm not sure what your definition of bottom is ??

Just got around to looking up threads to reset service indicator, and despite trying it in pitch dark with the aid of a maglite, after several glasses of wine, still managed to do it!

Well chuffed, it's just one of those little niggles isn't it!

And it's so satisfying to do this with a paperclip when you know you could pay somebody 50 to plug it into a computer to do the same thing!

Thanks forum!

I have been looking at these devices for resetting service interval mileage. I came across this one on fleabay but it says it only does it from 2001 onwards vehicles. Mine was first registered in Nov 2000. Is it out of range for this device?

ROVER 75 SERVICE INTERVAL RESET TOOL (http://cgi.ebay.co.uk/NEW-ROVER-75-SERVICE-INTERVAL-RESET-TOOL-UK-SELLER_W0QQitemZ160252544107QQcmdZViewItem?hash=it em160252544107&_trksid=p3286.c0.m14&_trkparms=72%3A1301%7C66%3A2%7C65%3A12%7C39%3A1%7C 240%3A1318)

I know I can use paperclips but as I am a bit doddery and have been known to have the shakes now and again, I thought that one of these gizmo's would serve me better than fumbling around on my hands and knees with a paperclip.

Also the price seems to have risen quite a bit, anyone know where they maybe cheaper?

Thanks

Car is a 2006 registered 75 Touring CDTi showing -23650 (never had a service ever presumably as mileage is 29,000 and the minging state of the air and pollen filters would also say this to me! Oil was pretty much like thin black treacle as well!)

Piece of cake, release the two quick release couplings for the diesel pipes and the electrical plug, unscrew the clamp and lift out the whole filter and head assembly, unscrew the filter anticlockwise ( I put the filter in a vice and gently turned the plastic head and it should screw off, put it all back together and turn on the ignition for 30 secs before attempting to crank it over (you'll hear the diesel pump through and the gurgling noises of it purging air) and that's it, dead easy!

Just reset my 2005 ZT CDTi - looks like the trick is to do it as quickly as possible after switching ignition to position number II (as it took me quite a few attempts!).

This site is invaluable for Rover/MG information!

hello all
just joined, what a thread.
i cant help but reply to cam4. when i read his message i cracked up, but my wife was behind me wearing a face pack,(its a woman thing).
when i read out the message, she laughed that much,here face cracked.
but seriously, i will do my 2000 75 cdt soon now that i have found out how to do it.
if you read about all the problems these and other cars can have, we probably would not by one. but being an old mechanic,they dont present to much problems,and the car (is) well worth buying. and at about 50 mpg you cant grumble at that.

Has anyone used or had any success with this type of device for resetting service counter? They are availabe online from China and state that they are suitable for R75 from 2001 onwards.
I am considering buying one, and would appreciate any feedback,
cheers Peter.

Used paper clips once then bought one of these, much easier and reliable. Worth every penny from China.

an update on my earlyer message. 2 bits of copper wire 1mm thick and 4 seconds later ,first try, reset. the worst job is getting in those water traps below the windscreen, ouch, once you have been in there once,its not to bad. the only drain hole i could clear was the n/side, even hoovered it out. well done rover,you could not have made it harder to reach a drain hole if you tried. its a must for every 75 owner to do this, but hey im 3 years to late to tell you all this. nice web site though.

Just reset the service counter on my Y reg 75 club 2.5 V6 auto put the wire in pin 8, turned key to second notch, then when the service counter came on i earthed the other end of the wire on the door pin, counted to 4 and removed the wire off the pin.
when i turned the ignition off and back on again the service counter was set back to 15000 again. BRILLINT STUFF keep it up.

Just been to looking to do this solution this morning; had a look at the plug and it appears that some of the metal connectors/plates in the plug are missing :(

My service mileage is at -22900 currently; is my plug damaged or do they all look like that?

Also; is it 1-8 left to right as you look at it or vice versa?

Hiya, just done mine. Had the service done today and they did not reset the indicator, so read on here and it worked. WOOHOO! :) mine is a 51 MG ZT 2.5 V6.

Oh and the pins run from the left as 8, 7, 6, 5, 4, 3, 2, 1. or basically as you look at it???

cool. I like this site, and I like my MG to, though I as reluctant to buy one first of all. and after shelling out for some new tyres I did think about getting rid of it, but after using the garages car while they were doing my service I missed my MG :( lol

Not sure if this is previously mentioned, but I found a tip that would make life easier.

I have just resent my 2001 (Y) MG ZT 190+ that had -38000 Oil Service and Inspection on the clock.

But instead of grounding Pin 8 to Pin 4, I inserted an 18" long wire to Pin 8 and when I turned the ket to position 2, I touched the other end to ground inside the door.

This made it easier to get at and I wasn't bent double under the steering wheel.

My clock is now rest to 15000miles.

Hope this helps.

I've just done it (24Mar2010) sucessfully on my 51Reg(02) Rover75 Diesel Auto. This time I used a 10K (10,000 Ohm) resistor as the legs are just the right length and there's NO DANGER of shorting anything!
1 second for Oil service, 8-20 secs for Inspection service reset.
I have previously used the wire method sucessfully for the oil service reset and Major service reset, so I'm sure any value below 10K will do.
N>B> 10K Ohms=12 Milliamps max short circuit current, 1k=120 mA max, a bit of wire can damage stuff if you touch the wrong place!

Chris75 says the diagnostic socket pin out as viewed from the seat is
16 ------ 9 Top row
8 ------ 1 Bottom row
There are 2 rows of 8 pins.
The bottom row is 1 to 8 from right to left.
The Rave cd shows it under electrical connectors,
#C0040 , although the photo is on a LHD auto!
Enjoy, TimAtBeet

just done my rover 53 reg diesel. connected piece of green garden tie wire(with plastic removed at both ends and which is the same thickness as a paper clip) into pin 8 and switched ignition to 2nd position and shorted other end to door hinge once the service indicator showed. held it for 20 secs. did it first time now back to 15000 miles. chose this method which is less fiddly. thanks for the info. the service mileage reduces each 25 miles driven, just in case you did not know.

hi i would just like to confirm this does work as i did it on a rover 75 cdti & used a paper clip & reset back to zero,but make sure you get correct pins before turning on ignition,good luck.

Thanks a bunch guys, saved me the 40 my local garage were quoting (after their tools said it couldn't be reset). Having just acquired the car, my indicator read -16900 miles so was very pleased that this easy method works!

Hi all,

Just tried the reset with a paper clip and it worked first time. Only bought the car last week and service indcator had -5250 on it but it had been service (although I'm not sure which type).

Anyway it now tells me that an Oil Service is due in 15000miles.

Thanks a mil:trophy:

Couldn't get it to work on the nut on the door, worked first time on a nut on the body. Probably a better earth on mine.

Because you may do the work on the car yourself? These cars aren't smart enough to detect a fluid/filter change, so after you've done a full service, the car's still gonna think you need to service it.

Must admit I see where JasonMGF is coming from.

This seems an easy way for a less than honest dealer/seller to claim "its just been serviced but I dont have the stamp", too.

Just done mine worked first time - ZT 190.
Only bought the car about 5 months ago, 90% full service history in book plus receipts for the other 10%. I will be doing all the oil changes etc myself so nice to know this tip.
