    Exclamation Re: OBDI Code Reference Thread

    I read the codes from the heater of my 94 Fleetwood and they are all 3 digits after the 2-digit prefix. I cn't find any reference to 3 digit codes.

    For example I got:

    00-120
    00-122
    00-130

    04-162

    05-10

    I haven't even seen a prefox above 04!

    Can anyone help me out?

    Thanks,

    Ray

    Re: OBDI Code Reference Thread

    I was curious about those three digit codes as well, and I'm sure that there are a few other people who might be interested too.

    Correct me if I'm wrong, but the 1 prefix just means that the code popped up at an early point in time and was either fixed or went away (miracle?), so the OBD keeps them there as a record.

    Re: OBDI Code Reference Thread

    I'm surprised that no one else has noticed this... Codes are useless unless you know how access them and/or what years they pertain to.

    To Retrieve Codes from a mid 80's Cadillac:

    1. Turn the ignition "ON". Engine can be either OFF or RUNNING.
    2. Depress the "OFF" and "WARMER" buttons on the ECC panel simultaneously and hold until "--" appears. "88" will then be displayed which indicated the beginning of the diagnostic readout.
    3. Trouble codes will be displayed on the digital ECC panel beginning with the lowest numbered code. Note that the MPG panel goes blank when the system is displaying as the diagnostic mode.

    *Clear codes by pressing OFF and HI simultaneously until "00" appears on the display
    ** Exit diagnostic by pressing "ECON" or "AUTO" or turning the ignition off for 10 seconds
    ***For a list of Mid '80 Diagnostic Trouble Codes, consult DopeStar's opening post or follow this link.

    To Retrieve Codes from a '90's Cadillac:

    1. With the ignition in the RUN position (engine does not necessarily need to be running, but it will work either way).
    2.Push (and hold) "OFF" and "WARMER" simultaneously on the Electronic Climate Control (ECC) until all telltales lights illuminate (segment check).
    3. Release the "OFF" and "WARMER" buttons.
    4. System is now in diagnostic mode. "00" (zero-zero) should now be displayed. This is the pointer.
    5. Pressing "OUTSIDE TEMP" will allow you to display the corresponding code for the pointer.
    6. Use the "FAN SPEED" override switch (UP/DOWN) to increment or decrement the pointer number.
    7. Pressing "AUTO" or turning the ignition switch OFF exits diagnostic mode
    8. Pressing "OFF" while a code is displayed will clear it

    *Pointers 00-04 Contain trouble codes (00=PCM, 01=CCM, 02= HVAC, and 04=ABS/Traction Control)
    **For a list of '90 Diagnostic Trouble Codes, consult FASSTWOOD's post or follow this link.

    NOTE: 1986 to 1989 Cadillac (Fleetwood) Brougham's must be diagnosed using the procedure outlined in my last post.

    Re: OBDI Code Reference Thread

    My name is Tim M. Proud owner of 1995 Fleetwood 350 LT1. The other day it started skipping at idle stoped at light. Replaced Opti at 98000 miles now showing 125000. When first cranked and running it is smooth. After it warms up it starts to skip a little. When completly warmed up it continues to skip at idle, and at speed but it still runs, and has not cut off. I stoped driving it until I can figure this out. I ran the diagnostics from the AC controls at different times, and days after running. Also overnight while cooled down. These are the codes over two weeks as they show from the AC controls. First time after running and two hour cool down:
    1st code check: 2nd right after warmed up Today 6-26-11 cooled over night, and not run:
    04-27 04-27 04-27
    05-10 05-10 05-10
    06-05 06-7 08-88
    13-03 13-03 13-03
    23-58 23-58 23-58
    28-95 29-38 24-26
    29-33 30-71 29-23
    30-76 31-55 30-90
    31-66 00-35 31-89
    36-23 37-50
    37-50 38-04
    38-04
    Please help me get rid of my skip! I can replace or clean any sensors that need it. Again 1st run while cool she's sweet but when she warms up she starts skipping. Thank you for your time, and help with this situation.

    Re: OBDI Code Reference Thread

    The only trouble code you have is 0427, which indicated a malfunction in one of the wheel speed sensors.

    Everything else, from 05-38, is general information about the computer, air conditioner, and engine, such as the program number, engine temperature, sun load, and in car temperature.

    I just picked up a '94. Does OBD-I show you historical codes? Or do you have to pull them while the light is on?
