PCM Security Relearn Procedure
for 1998-02 Buick Regal GS and 2000-02 Chevrolet Monte Carlo


In the event that your vehicle fails to start after installing the PCM, you will need to perform the Security Relearn Procedure. This procedure allows the PCM to function properly in your vehicle. Follow the steps listed below completely.

Security Relearn Procedure Steps
1.) Attempt to start the car by turning the key to the Start/Run Position.

2.) Observer that the vehicle fails to start and that the security light is illuminated.

3.) Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'OFF' position).

4.) Allow the vehicle to sit with the key in the 'ON/Accessory' Position for at least 11 minutes.

5.) Turn key to 'OFF' position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.

6.) Repeat steps 1-5 for 3 cycles.

7.) On 4th attempt, your car should now start.

NOTES:
- Since this is a fairly long procedure, it is recommended that you limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.

- It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time (i.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.).

When properly executed, this procedure should take approximately 35 minutes to complete.
