EBW Posted June 11, 2021 Report Share Posted June 11, 2021 EJJEThis is how to access and clear codes on your Eldorado. No OBD scanner is needed. To Access Codes Switch ignition ON. Simultaneously press and hold the A/C control panel ‘OFF’ and ‘WARMER’ buttons . When all segments of the display illuminate: o Release the A/C control panel ‘OFF’ and ‘WARMER’ buttons. Trouble codes will be displayed on the driver information display. Trouble codes will be displayed in ascending order. NOTE: All ECM codes start with the letter ‘P’. Trouble codes for other systems may also be displayed. All current trouble codes end with the letter ‘C’. All history trouble codes end with the letter ‘H’. If no ECM trouble codes are stored, ‘NO E CODE’ or ‘NO P CODE’ will be displayed. NOTE: If ‘NO E DATA’ or ‘NO P DATA’ is displayed there is a communication problem between the ECM and the instrument panel. • When all trouble codes have been displayed: o Press the ‘AUTO’ or ‘DEFOG’ button or switch ignition OFF. Erasing Switch ignition ON . Simultaneously press and hold the A/C control panel ‘OFF’ and ‘WARMER’ buttons. When all segments of the display illuminate: o Release the A/C control panel ‘OFF’ and ‘WARMER’ buttons. • Trouble codes will be displayed on the driver information display. NOTE: Pressing and releasing the ‘LOW’ button will bypass trouble code display. • When all trouble codes have been displayed: o Press and release the ‘LOW’ button until ‘PCM’ is displayed. Press and release the ‘HI’ button. Press and release the ‘LOW’ button until ‘PCM CLEAR CODES’ is displayed. Press and release the ‘HI’ button. ‘PCM CODES CLEAR’ will be displayed for 3 seconds. Press the ‘AUTO’ or ‘DEFOG’ button or switch ignition OFF. rockfangd 1 Quote Link to comment Share on other sites More sharing options...
ejje Posted June 11, 2021 Author Report Share Posted June 11, 2021 Hi, thanks for information. Just a probleme, I´m from Sweden and an old man 80 and not so good in English and not good at special technical nomenclature so can you give a small explanation what ECM,PCM stand for. Thanks again for help. Quote Link to comment Share on other sites More sharing options...
EBW Posted June 11, 2021 Report Share Posted June 11, 2021 Engine Control Module (ECM) Powertrain Control Module (PCM) Basically two different names for the car's computer system. They are often used interchangeably. Quote Link to comment Share on other sites More sharing options...

ejje Posted June 15, 2021 Author Report Share Posted June 15, 2021 Have tried to do as instructed but I have no Low and Hi button. Can it differentiate between 4.6l and 4.9l engine? maybe year model? Quote Link to comment Share on other sites More sharing options...

Can it differentiate between 4.6l and 4.9l engine? maybe year model? The controls for the climate control are the same for either engine for the 1992-1994 Seville. I have marked the buttons with their functions. If you have an owner's manual, they are also in there. If you don't have one, there are several websites that you can download a digital copy, if you want one. rockfangd 1 Quote Link to comment Share on other sites More sharing options...

Disconnecting the battery will eventually delete most of the codes, but it will also set codes indicating the PCM has lost power. It is far better and quicker to delete the codes through the procedure previously described. Quote Link to comment Share on other sites More sharing options...

Har hittat flera youtube filmer men ingen som visar min instrumenttavla, inget är likt. Det som kommer upp är inte heller likt det som sägs i ovanstående instructioner. Förstod att det var fläktens hastighet low and high. Har gått igenom instructionerna men som sagt inget är likt. Quote Link to comment Share on other sites More sharing options...

rockfangd Posted June 17, 2021 Report Share Posted June 17, 2021 Welcome to the forum. Great members here from all over😁. Just out of curiosity is there any issues while running? Any check engine light? The OBD1 rarely throw the light unless the problem is occurring.

ejje Posted June 22, 2021 Author Report Share Posted June 22, 2021 (edited) Hi again, a new probleme with the car. Where can I find new rubber bushing/washer, 14-16 pcs ? See picture. Edited June 22, 2021 by ejje Quote Link to comment Share on other sites More sharing options...
rockfangd Posted June 25, 2021 Report Share Posted June 25, 2021 What is wrong with them. I'm sorry but I highly doubt you will find them anymore. How many do you need? The rubber bushing? or the spacer that goes on the stud? Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
ejje Posted July 19, 2022 Author Report Share Posted July 19, 2022 12 pcs the rubber bushing. Quote Link to comment Share on other sites More sharing options...

ejje Posted November 13, 2023 Author Report Share Posted November 13, 2023 Hi again, long time ago. I managed read the codes. H:, s055,s061,p053,p083,p095 C:, t072,t073,s044 I managed clear but the C codes did not go away. Is there a manual when I can find all codes and what they stand for. I have 2 big books, Service manual 1 powertrain and the service manual 2 chassies and body but I can´t find all codes in there. Thanks Quote Link to comment Share on other sites More sharing options...
