Important: Use this procedure only if replacing the theft deterrent module (TDM) using the existing vehicle keys.
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.
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.Important: Use this procedure only if replacing the theft deterrent module (TDM) using new vehicle keys.
Important:
• When performing the 10-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure. • Use only a master key when performing the first relearn procedure. If you a valet key is used first, the TDM will not allow additional keys to be learned.
Use this procedure after replacing any of the following components:
• | The vehicle keys |
• | The theft deterrent module (TDM) |
• | The engine control module (ECM) |
Important: When replacing either the vehicle keys, PCM, or TDM and the 10-Minute Relearn Procedure is used, ensure that the appropriate calibration is selected for the replacement component on the calibration selection screen of
the service programming system. The appropriate calibrations for specific vehicle theft deterrent (VTD) system components are described below.
• When preparing a TDM for replacement, the Prepare Module For TDM Setup Procedure calibration is required. This allows the retrieval of required information from the TDM prior to its replacement. • When learning vehicle keys and the 10-Minute Relearn Procedure is used, the Vehicle Theft Deterrent Learn For Learning Replacement Keys calibration is required. This clears all previously learned keys from the TDM and enables the TDM to learn new
vehicle keys. For learning additional vehicle keys, refer to
Adding Keys
. • When replacing a TDM or ECM and the 10-Minute Relearn Procedure is used, the VTD Learn for Powertrain calibration is required. This clears the previously learned fuel continue password in the ECM and enables the ECM to learn the fuel continue password
of the new TDM.
Important: When replacing a TDM with a GM SPO Replacement Part, insure the Setup a New TDM procedure is performed prior to the 10-Minute Relearn Procedure.
Important:
• The scan tool will initially display 12 Minutes. The first 2 minutes allow the scan tool to initialize the appropriate control module. The remaining 10 minutes is the relearn timer. • On some vehicles the security indicator may be illuminated on steady for the duration of the 10-Minute Relearn Procedure.
Use this procedure after replacing any of the following components:
• | The PASS-Key III plus keys |
• | The theft deterrent module (TDM) |
• | The powertrain control module (PCM) |
Important:
• This procedure is not available on vehicles equipped with EXPORT configured TDMs. • When performing the 30-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure. • When replacing a TDM with a GM SPO Replacement Part, ensure the procedure to setup a new TDM is performed prior to the 30-Minute Relearn Procedure.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.
