If the theft deterrent control module is replaced using the existing vehicle keys, the following procedures must be performed:
IMPORTANT:
Because of how vehicle key information and theft deterrent passwords are stored within the theft deterrent module (TDM), the Set Up a New Theft Deterrent Module procedure must be performed prior to the removal and replacement of the TDM if the vehicle keys are being reused. Performing the setup procedure first allows the scan tool to extract the key information and passwords from the old TDM prior to its removal. Failure to perform this step will result in the failure to learn the existing vehicle keys and new vehicle keys will be required when replacing the TDM.
- Set up a new TDM using existing keys. Refer to Programming Theft Deterrent System Components . This step will retrieve key information from the original TDM and write this information to the replacement TDM.
- 10-minute Relearn Procedure. Refer to Programming Theft Deterrent System Components . Use the VTD Learn for LE5 or LZ9 Powertrain System calibration with this step. This step will allow the engine control module (ECM) to learn the replacement TDMs incoming fuel continue password.
