IMPORTANT:
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.
If the existing vehicle keys are not being reused, the TDM is to be replaced prior to performing of the setup procedure.
If the existing vehicle keys are not being reused, the TDM is to be replaced prior to performing of the setup procedure.
