For 1990-2009 cars

### Programming Procedure (Passlock™)

There are 2 methods used to program/reprogram the Passlock™ system. These are the Saturn service stall method and the auto learn method.

### Saturn Service Stall Method

• | This method takes about 10 minutes for programming.

• | A programming system is required. Refer to Saturn Service Stall/Tech 2 User Guide.

• | A scan tool is required.

### Auto Learn Method (Optional)

• | This method is usable if the Passlock™ sensor ECM/PCM 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-lean 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. The password from the BCM to the PCM/ECM requires the Saturn service stall to learn the new password in order to enable the fuel and start the vehicle. Initiate the 10 minute relearn procedure.
3. The RKE transmitters will carry over from the previous BCM when using the Saturn service stall system.

#### PCM: (4 cylinder)

The Saturn service stall system will be required. Initiate the 10 minute relearn for the fuel to enable the password from the existing BCM.

#### ECM: (6 cylinder)

The Saturn service stall system will be required to initiate the 10 minute relearn for the fuel to enable the password from the existing BCM.

#### TCM: (6 cylinder)

No relearn required for the controller replacement.

#### Passlock™ Sensor (Ignition Module)

The Saturn service stall will be required to initiate the 10 minute relearn procedure for the existing BCM.
