Instrument cluster diagnostic test

[massey]

I have read on this forum about the instrument cluster diagnostic test.

Does anyone have any experience doing this?

It stated on the link I read that the menu ranges from 1 to 19!
I can only go from 1.0 to 1.7!

Anybody any ideas?

My engine management light is on thats why I am enquiring.

I've set out below my revised instructions for accessing -

Diagnostic Mode

The following comes from a BMW document and may be ambiguous in parts due to differences in the MGR system. I have made the instructions easier to follow than the original. Any errors in this revised data are mine. Failure to activate the diagnostics routine is usually due to not pressing the button fast enough. If pressing is delayed for more than a second or so, it will revert back to the standard trip display. There are bits of it I don't understand, but most of the useful stuff is explained.

To enable the on-board diagnostics:

a) Put key into ignition and turn it to position 1 (instruments activated).
a2) If you intend driving with diagnostic mode active, start the engine now.
b) Press and hold the trip reset button.
c) Your LCD display will show "test 1.-"
d) Immediately press the reset button every half second until you get to "test 19.-". (19.0 allows access to diagnostic mode)
e) The display will now show alternating "Log 1 -on" / "Log 1 -off"
f) While it shows "Log 1 -off" press the reset button and. .
g) With no delay press within a half second (repeatedly if necessary) to get to the required section.
h) The screen will appear similar to the earlier one, but is a different series. Keep pressing every half second to select one of the following functions (there is no title on screen):

1 Car, Engine and cluster data
1.0 VIN serial number
1.1 K-number
1.2 Cluster Part Number
1.3 Coding (04)/diagnosis (52)/bus index (10)
1.4 Week of manufacture (eg. 1200 = week 12)/year of manufacture (eg. 2000)
1.5 Hardware number (eg. 09) and Software number (eg. 11600 = 16.0) of IPK.
1.6 Injection Status-number of cylinders-motor number

2 Cluster System Test
2.0 Activates the gauge drivers, indicators and LEDs to confirm function.
When function 2.0 is selected, the instrument pack provides a check of the warning lamps, major and minor gauges, displays and illumination functions. The gauge pointers are driven through their full arc and back again to check operation. All warning lamps are illuminated to check that none of the LEDs have failed. All yellow and red pixels of the message centre are flashed on and off in a chequered pattern to check that all elements of the display are functional.

3 Service Inspection (SI) Data
3.0 Fuel Used (in liters) since last Service Inspection
3.1 Periodic inspection days; elapsed days (since last SI)

4 Momentary Consumption
4.0 Momentary fuel consumption in liters/100km (eg. 0145 = 14.5 liters/100km)
4.1 Momentary fuel consumption in litres/hour (eg. 0018 = 1.8 l/hr)

5 Distance Gone Consumption
5.0 Average consumption in litres/100km (eg. 082 = 8.2 liters/100km)
5.1 Calculate distance ( km) to refuel (momentary distance to go)

6 Fuel level sensor outputs in liters (Fuel tank has left and right side sensors)
6.0 Fuel levels both (eg: 109330 means left half sensor = 10.9 liters; right half sensor = 33.0 liters)
6.1 Total tank level totalled (eg: 0439 is 10.9+33.0 = 43.9 liters)
6.2 Indicated value with diagnostics: The Test Number (6.2) is preceded by 1, 2 or 3 (eg. 1-6.2 or 2-6.2 or 3-6.2)
If first digit is 1 - both sensors are OK. This is followed by three left signal digits, then three right signal digits.
If first digit is 2 - one sensor has an error. Side in error will display - - 0 . Functional side will show its three digits
If first digit is 3 - no sensor signal, no display. Probably - - 0 - - 0 (Needs confirming -TC)

7 Temperature and Speed
7.0 Coolant/Engine temperature (eg: 021+ is 21°C)
7.1 Ambient/Outside temperature - changes every 0.5 degree Centigrade. (eg.125/130/135 is 12.5°/13.0°/13.5°C)
7.2 Engine speed / Current (RPM)
7.3 Vehicle speed / Current Speed (km/hour)

8 Values of 7.0 to 7.3 in HEX form (Unknown)

9 Battery
9.0 Battery Voltage (eg: 140 = 14.0v)

10.0 Country code

11.0 Unit code

12.0 Not used

13.0 Gong test

14.0-14.4 Error memory: if 000000 no error in memory

15.0 - 18.0 not used

19 Lock Status (unlocks functions in range 3-18) ??
19.0 Log1-On/Log1-Off Unlocks diagnostic regime: To access, press button when Log1-Off shows

20 Correction Factor for OBC Fuel Consumption display
Formula for the Correction Factor:
Factor = Indicated Consumption X 1000 / Measured Consumption (Do this using brim to brim calculations)
(eg: Factor = 1234 Press Reset button to begin setting the of the first digit (4) - digits will start to increase so press reset when the correct digit appears
20.1 Setting of the second (3) digit as above
20.2 Setting of the hundred (2) and thousand (1) digit
20.3 Store and Display the Correction Factor

21.0 Software Reset; reset OBC settings

There are a good few posts on here detailing the exact procedure to enter the mode that will enable you to progress past 1.7, read them very carefully as the first time i tried i had the same problem as you.
As for your check light on i think you should invest in a T4 session at your local Rover specialist to determine exact cause of said light, it`s not expensive and could save you hundreds of pounds.

T-cut is your man!

When i tried it I was only able to choose from the group 1 options and then returned to 1.0.

I will try again and let you know, thanks T-Cut.

What exactly will this do if i do get it going?
Will it give me a code or message diagnosing the reason my engine light is on?

[massey]

OK re tried this and got it going.
Will this help in anyway let me know why my engine management light is on?

T4 session

Quick answer no - all the test does is check the drivers of the instruments and check the led's are working.

The best idea regarding the engine management light being on is have a diagnostic check at a garage - preferably T4 and at a MGR specialist.

How much is the equipment to diagnose the MG ZT?
Would the same one also do a 2000 R45?
I begrudge payin garages their extorsionate fees.

I have seen prices for a T4 ranging from 3 to 7 thousand. If you can find them.

A few members around the country have them and are willing to do a session at a very reasonable price. Where abouts are you?

We just need someone who can write a software package to run of a laptop.

What about these OBD hand held readers I have heard about anything like that suit this?
Roughly how much is a session?
This is just diagnosing the problem then then repair is in addition to this as well right?

I have a hand held one but they are quite limited in what they can do. A session on a T4 with a member usually costs about £30 - £50. You maybe surprised to find there are quite a few around the country who are willing to do it. Where are you?

Northern Ireland. Co Down not expecting as many options here as in the main land I guess?!

I think there is someone there with one. Maybe start a thread asking for a session on a T4 in Ireland and see what happens. Never know without asking.
