Alarm Module: Service and Repair
Theft Deterrent Module Replacement
Removal Procedure
Note: Because of how vehicle key information and theft deterrent passwords are stored within the 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.
Do not use the scan tool for any other programming operations while performing this procedure. Doing so will erase the stored data retrieved from the
original TDM and cause the set-up to fail.
1. Remove the ignition switch. Refer to Ignition and Start Switch Replacement (See: Powertrain Management/Ignition System/Sensors and Switches
- Ignition System/Ignition Switch/Service and Repair).
2. Remove the theft deterrent control module screws.
3. Remove the theft deterrent control module.
