The 97+ cluster unit has 15 test positions what do they all mean?
I have figured out RPM, Km/H and a wierd hexidecimal gas reading.
I know one is for the manipulation dot on the cluster that lets you know if someone has messed with the cluster. I don't remember what test # it was.Originally Posted by Beamin'
When I get home from school, I will look in the TIS, it might have them.
Test 1: Instrument self test
Test 2: Engine Data - This display is an "engine factor" value that is stored
in the coding plug. The instrument cluster processor uses this factor in
addition to the "TD" signal from the DME control module to process and
display tachometer RPM based on the engine installed. For EXAMPLE:
*ENGINE FACTOR 2 = 4 CYLINDER
*ENGINE FACTOR 3 = 6 CYLINDER
*ENGINE FACTOR 4 = 8 CYLINDER
Test 3: SI elapsed distance - the total mileage in kilometer since the last
reset. Which service is due at the next inspection (OIL SERVICE or INSPECTION)
Test 4: SI elapsed days - no value for US vehicles. Relates to Euro annual inspections.
Test 5: SI evaluation factor - for engine speed and temp. thresholds being passed.
Display: n = 0 or 1. engine speed (over-rev)
t = 0 or 1. engine temp.
Test 6: Fuel Level and coolent temp. - Display of hexadecimal codes in
relation to gauge position.
Fuel gauge Hex value
A (empty)----------> 0d
End of reserve------> 37
B-------------------> 54
C-------------------> 90
D-------------------> c4
E (full)--------------> f0
Engine temp. Hex Value
A-------------------> ce
B-------------------> 6d
C-------------------> 5c
D (center)----------> 4f-23
E-------------------> 1e
F-------------------> 18
Test 7: Engine speed - display of current engine speed
Test 8: Road speed - display of current road speed in km/h
Test 9 Distance reading - this allows the total stored mileage to be updated
if one of the storage components has to be replaced. This test step will be
used if the manipulation dot is illuminated in the cluster display. Ths
display will show the component with the lower mileage. For example:
Display of 012654 l indicates that the mileage in the internal EEPROM is
lower than the milage stored in the coding plug.
Display of 000325 E indicates that the mileage in external coding plug is
lower then the total mileage stored in the internal EEPROM.
Pressing the reset button for 4 seconds will over write the lower mileage
with the higher mileage and cancel the manipulation dot. The SI data will
also be transferred at the same time.
Test 10: Status bits (input signals) - the status of digital inputs to the
cluster are displayed as 0 or 1. Display: 0 = input low, 1 = input high.
_ _ _ _ _ _ <--- Mileage display...6 digits left to right
1st - belt contact, seat belt fastened = 0
2nd - ignition lock contact, key inserted = 0
3rd - door contact, door open = 0
4th - clock button pressed = 0
5th - SI reset = 0, for reset = 0
6th - EGS transmission failure = 0
Test 11: Status Bits (output signals) - the status of digital outputs is displayed.
Display: 0 = output inactive, 1 = output active
_ _ _ _ _ _ <--- Mileage display...6 digits left to right
1st - Gond output
2nd - Brake warning lamp
3rd - Low fuel warning lamp
4th - EGA lamp
5th - seat belt lamp
6th - manipulation dot
Test 12: not used
Test 13: Country code of cluster - the display indicates the country version
of the cluster. This cannot be changed in the workshop. Display: USA 02
Test 14: Software Reset - The reset must be carried out if any faults are
present that are not plausible before any components are replaced. After the
reset, the system will exit the TEST mode and the lock will be reactived.
Test 15: lock/unlock
NOTE: KLR means ignition switch position #1 (accessory) KL-15 is ignition
switch position #2 (on), and KL-50 is ignition position #3 (start) "TD" is
engine speed signal. Try not to use the engine speed and road speed while
driving. The display is too low and you have to read instead of glancing
which takes too much time taking away your eyes off the road.
Hope this test brings some fun and interest to you all.
Nevermind..........
