Step 1: Entering the Feature Customization Mode

When performing BCM diagnostics, the first step is to enter the feature customization mode. During this mode the BCM identifies itself, so that vehicle's option content match with BCM's capabilities.

To enter the feature customization mode:
1. Turn the ignition switch to the LOCK position.
2. Remove the BCM PRGRM fuse.
3. Turn the ignition switch to the ACC position.

Upon entering the feature customization mode, the BCM flashes the fasten belts indicator and sounds the chime 2, 3 or 4 times which is equal to the BCM type installed on the vehicle. Check that the BCM installed on the vehicle is compatible with all of the features on the vehicle. If not, then replace the BCM with the proper type.

At this point, the following vehicle systems have features that can be customized (refer to the following for details):
^ Interior lighting. Lighting and Horns
^ Automatic door lock.
^ Keyless entry. Keyless Entry
^ Content theft deterrent. Antitheft and Alarm Systems
