Test Description

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 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:  Verifies the condition for setting DTC B3055 is current.
  2. 3:  The key must be a Passkey III (PK3) transponder key with an operating transponder for the system to work.
  3. 4:  The only method to confirm whether the transponder in the key or the theft deterrent control module is malfunctioning is to try a alternative component in the system. The vehicle was delivered with 2 keys.
  4. 5:  The possibility is unlikely that more than one key will be defective. If all keys do not work, the theft deterrent control module must be malfunctioning.
  5. 6:  If the vehicle has a malfunctioning theft deterrent control module that malfunctioned during an ignition cycle, the system will be "fail enabled" and the vehicle will start for all keys.
  6. 7:  If a new key must be tried, the key must have the proper mechanical cut and the theft deterrent control module must "learn" the transponder value.
  7. 8:  If only one key was available for the vehicle and the replacement key does not work, the theft deterrent control module must be malfunctioning.
