    What do the Odometer test codes mean?

    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.

    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.
