Auto Learn Method (Optional)

^ This method is usable, if the Passlock sensor, ECM replacement was required.
^ This method takes about 30 minutes.
^ A Scan tool is not required.

Both methods are included in the flow chart security system relearn procedure

IMPORTANT: If no passlock components are replaced the 30 minute auto-learn can always be used.

The following shows when the relearn procedure needs to be performed.

Controller Replaced:

BCM:
1. The new service BCM will automatically learn the voltage code from the Passlock sensor.
2. Password from the BCM to the PCM/ECM requires the Saturn Service Stall to learn the new password in order to enable fuel and start the vehicle. Initiate the 10-minute relearn procedure.
3. RKE transmitters will carry over from the previous BCM when using the Saturn Service Stall System.

ECM.
1. The Saturn Service Stall System will be required initiate the 10-minute relearn for the fuel enable password from the existing BCM.

TCM: (6 cylinder)
1. No relearn required for controller replacement.

Passlock Sensor (Ignition Module)

1. The Saturn Service Stall will be required to initiate the 10-minute relearn procedure for the existing BCM.
