Test Description

WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 2. To set this code, the password that the PCM has learned does not agree with the password being received from the theft deterrent control module. This condition can occur if the theft deterrent control module has been replaced and the programming theft deterrent system components procedure has not been performed.
  2. 4. If the PCM resets the DTC after the programming theft deterrent system components procedure has been performed, the theft deterrent control module is malfunctioning.
