pcg Posted November 13, 2010 Report Share Posted November 13, 2010 I know the info is here but I just can't seem to find it. Could someone please point me to the information as to how to access the trouble codes in my 94 fleetwood using the climate control system. Thanks in advance!!

pcg Posted November 13, 2010 Author Report Share Posted November 13, 2010 Well I found it on another site and thought I might as well share it here. As I said, I'm sure it is already here somewhere but here it is again. I'm sure the admins will delete it if it is redudnant. 1995 Fleetwood AC electrical or computer issues Your Cadillac is equipped with a very good on-board diagnostic system capable of reading out the stored trouble codes. To enter diagnostic mode: * With the ignition in the "RUN" position (engine does not necessarily need to be running, but it will work either way). * Push (and hold) "OFF" and "WARMER" simultaneously on the Electronic Climate Control (ECC) until all telltales lights illuminate (segment check). * Release the "OFF" and "WARMER" buttons. * System is now in diagnostic mode. "00" (zero-zero) should now be displayed. This is the pointer. * Pressing "OUTSIDE TEMP" will allow you to display the corresponding code for the pointer. * Use the "FAN SPEED" override switch (UP/DOWN) to increment or decrement the pointer number. * Pressing "AUTO" or turning the ignition switch "OFF" exits diagnotic mode. Pointers 00-04 contain the stored trouble codes. * "00" = Powertrain Control Module (PCM) codes * "01" = Central Control Module (CCM) codes * "02" = Heating, Ventilation and Air-Conditioning (HVAC) codes * "03" = Supplemental Inflatable Restraint (SIR) codes * "04" = Anti-lock Brake/Traction Control System (ABS/TC) Codes Codes prefixed by a "1" are history codes. A code can be cleared by pressing the "OFF" button while that particular code is being displayed. 1993 5.7L Throttle Body Injection, VIN 7 1994-1995-1996 5.7L Fuel Injection, VIN P Powertrain Control Module (PCM) Codes Code Description 00-11 ........................................
