SOURCE: How to reprogram computer in 1997cadillac DeVille without driving it someone help please.

You can't program this unless you have a GM TECH 2 scan tool, so not sure what you are referring to about "programming" it. Do you mean clear the drive cycle OBD2 test?

How do I reset the computer after I change the oil on a 2002 Cadillac Deville?


Turn the ignition to run (one position before starting engine). Display the Oil Life message by pressing the INFO button.
Press and hold the RESET button until the display shows 100% Engine Oil Life.
Turn the ignition off and then start the engine to verify the indicator has been reset.

2001 cadillac deville security light won't turn off


It should have Turned off with the Insert of the Newly Programmed Key. If Not, It may need a Computer Reset. You Can try Pulling the ECM Fuse for 5 Min. to Reset the Computer. If this does not work, Try disconnecting the Battery and Reconnecting. Make sure that you have a RadioCode before Disconnecting the Battery Though. Please Rate My Response! Thanks!
