Programming A New Body Control Module

Important
Any new body control module (BCM) will automatically program to the resistance of the key (or interrogator setting) being used at the first ignition "ON" cycle. This can only be done once for the life of the module.

A new BCM is not programmed. Before the system will function properly it must be programmed to the code that matches the customer's keys.
1. Install new BCM.
2. Insert one of the customer's keys into the ignition lock cylinder and turn it to the "ON" position.
^ It is good to start the engine at this time to verify system operation.
3. Observe the "SECURITY" indicator lamp.
^ The indicator lamp lights for about five seconds and then goes out.
- Indicates that the BCM is programmed properly.
^ he indicator lamp flashes at a rate of one flash per second until ignition is "OFF"
- Indicates that the BCM did not program and the system components, wiring and contacts should be checked for a fault.
