krazyhorse Posted November 17, 2004 Report Share Posted November 17, 2004 Hello every one, would some one please be kind enough to tell me the procedure for checking the codes on my 01 Seville. My wife said today the Service Engine Soon light came on. We are 65 mi. from dealer and I want to check them before I call. I have read some post on earlier models but didn't know if they were same. thanks for any help. Alan Link to comment Share on other sites More sharing options...
adallak Posted November 17, 2004 Report Share Posted November 17, 2004 Alan, Try what you found in archives and see if it works (should). It's not going to hurt something. Just take them (the codes) down and report. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
JimD Posted November 17, 2004 Report Share Posted November 17, 2004 This should work for '01.... 1998 - 2004 Seville ; On Board Diagnostics Display You will use the 3 switches located to the right of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC. ON/OFF = YES INFO RESET = NO INFO DOWN or INFO UP = manual toggle Ignition ON, acknowledge any warning messages; press ON/OFF and INFO UP together for 2 to 3 seconds. Everything in front of you lights up for 4 or 5 seconds, then you will see: Display shows "ALL?" Answering YES will display "ALL CODES?" Answering YES will run automatic test sequence and display codes, if any. Systems and codes will scroll faster than I am able to read them and write them; not to worry. "ALL CLEAR CODES?" will display at the end of the automatic test. If you are satisfied you have the information you need, answer YES to clear/erase all error codes. Answering "ALL?" with INFO DOWN will toggle systems test manually in order. Answering "ALL?" with INFO UP will toggle system test manually in reverse order. Press INFO RESET to reset DIC to "ALL?" to start again. Ignition OFF to exit. SYTEMS: ABS (Antilock Brake System) AMP (Amplifier) DDM (Door Driver Module) DIM (Dash Integration Module) IPC (Instrument Panel Cluster) IPM (Instrument Panel Module) IRC (Integrated Radio Module) PCM (Powertrain Control Module) RFA (Remote Function Actuation) RIM (Rear Integration Module) SDM (Sensing and Diagnostic Module) Includes airbag crash data. Under RF seat VTD (Vehicle Theft Deterrent) MSM (Memory Seat Module) TTM (Tilt/Telescoping Module) RSS (Road Sensing Suspension) Jim Drive your car. Use your cell phone. CHOOSE ONE !

danbuc Posted November 17, 2004 Report Share Posted November 17, 2004 DDM 1713 Mirror Switch Down Right-Stuck To High- no DDM 1718 Power Fold Switch Stuck High-no IPC U1016 Loss Of Communications with PCM PCM P0404 EGR Sytem Performance TTM U1016 Loss Of Communications with PCM VTD B1009 EEPROM Checksum Error VTD B2734 Coded Key Controller Memory Failure PCM U0404 is the only code out of all of those that should have turned on the "Service Engine Soon" light. I got most of those just from having a loose terminal on the battery. The only one actually associated with the engine is PCM P0404. (EGR System Performance) This diagnostic test checks for a malfunction in the circuitry and hardware of the linear EGR valve. The ability of the PCM to control the EGR valve is checked with this test. When the PCM commands the EGR valve to a desired position and changes that position less than a calibratable amount, this test then checks the EGR pintle position error. If the pintle position error, which is the difference between the desired pintle position and the actual pintle position, is too great then this DTC code is set. In other words, the EGR valve is not operating as well as the PCM would like. If the car still runs fine, you probably just need to clean the EGR valve. It's most likely getting stuck when the PCM goes to test it. Good luck. Link to comment Share on other sites More sharing options...
adallak Posted November 17, 2004 Report Share Posted November 17, 2004 As a rule if you have too many codes check the battery terminals , ground etc. for bad electrical contact. Clear all codes. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
