Theft Deterrent Control Module Replacement Using Existing Keys
WARNING: This page is about a different car, the 2005 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
If the theft deterrent control module is replaced using the existing vehicle keys, the following procedures must be performed:
IMPORTANT:
The theft deterrent module (TDM) contains specific values needed by the existing vehicle keys. This information must be extracted prior to TDM replacement. Information contained within the original TDM must be unlocked through the 10-minute Relearn Procedure in order to extract this information.
- Set Up a New Theft Deterrent Module (TDM) Using Existing Keys-Refer to Programming Theft Deterrent System Components
in Theft Deterrent.
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
in Theft Deterrent. Use the VTD Learn for L61 or VTD Learn for LX9 calibration with this step.
This step will allow the powertrain control module (PCM) to learn the replacement TDMs incoming fuel continue password.
