Devin O'Conor Posted October 14, 2007 Report Share Posted October 14, 2007 Can someone tell me which override is Set Temperature Offset on a 1998 DeVille? I could only find instructions for OBD I cars and for 1996. Can this still be done on a 1998 DeVille? I did it on my 1995 SLS and was much happier with the climate control performance. I didn't have to keep the temp set real low to stay comfortable. K.O.T. Link to comment Share on other sites More sharing options...
Ranger Posted October 15, 2007 Report Share Posted October 15, 2007 I seem to remember reading something about that in my '97 FSM so I think it can be done. Link to comment Share on other sites More sharing options...

Bruce Nunnally Posted October 17, 2007 Report Share Posted October 17, 2007 IPS06 This code allows the HVAC system set temperature to be different from the driver commanded (CCC or CCP) set temperature from -5°F to 5°F. Important If any of the override values are changed and the following procedure is not followed, DTC B1557 may be set. DTC B1557 may not be cleared. DTC B1557 is a non-recoverable condition. Replace the IPC if DTC B1557 is present. If the OFF button is pressed and the IPC displays the IPC CLEAR CODES message, exit the vehicle diagnostic system and start over. This action resets the override options back to the original values and prevents DTC B1557 from setting. The current override value is displayed in the trip odometer display. Follow the procedure below in order to change the override value. Add the value of the new feature (shown on the right) to the displayed override value. Increment the value by pressing the appropriate button below: Digital IPC -- the CCC warmer (RED) button Analog IPC -- the CCP PASS warmer (up arrow) button Decrement the value by pressing the appropriate button below: Digital IPC -- the CCC cooler (BLUE) button Analog IPC -- the CCP PASS cooler (down arrow) button In order to permanently store the new value, press and hold the buttons below until the new displayed override value flashes once (approximately 5 seconds): Digital IPC -- the front defrost (symbol) and the AUTO/ECON buttons Analog IPC -- the front defrost (symbol) and the A/C buttons Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
