Each of the following service procedures requires programming or setup procedures to be performed on the theft deterrent control module.

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.

1. 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.

2. 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.

If the theft deterrent control module is replaced and new vehicle keys are being made, the following procedure must be performed:

1. Set Up a New Theft Deterrent Module (TDM) Using New Keys--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

This step will set-up the replacement TDM.

2. 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.

If a key is replaced, the following procedure must be performed:

Replacing Keys--Refer to Replacing Keys in Theft Deterrent.

If a key is being added, the following procedure must be performed:
