Feature Customization - Entering Programming Mode

When performing the BCM diagnostics, enter the feature customization mode. During this mode the BCM identifies itself. This ensures that both of the vehicles option content match with the BCM capabilities. In order to enter the feature customization mode perform the following steps:
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 time which is equal to the BCM type used on the vehicle. Ensure 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.

The following vehicle systems have features that can be customized:
^ Interior Lighting
^ Automatic Door Lock
^ keyless Entry
^ Content Theft Deterrent Entering The Diagnostics Mode

Complete the following steps in order to enter the diagnostics mode:
1. Ensure the BCM is in the feature customization mode.
2. Turn the ignition switch from the ACC position to the LOCK position, then back to the ACC position within 1 second.

Complete the following procedure in order to confirm the BCM has entered the diagnostics mode:
1. Ensure that all of the vehicle doors are closed.
2. Open and close any vehicle door.
3. Fasten and release the driver seat belt. The BCM sounds the chime when receiving an input signal such as opening a door or fastening the driver seat belt when the BCM is in the diagnostics mode.

If the BCM does not sound the chime upon opening a door or fastening the driver seat belt, repeat Step 1 of Entering the Feature Customization Mode. If the BCM does not enter the diagnostics mode, then refer to A Diagnostic System Check - Body Control System. Testing and Inspection

Upon entering the diagnostics mode, the BCM flashes the fasten belts indicator and sounds the chime a number of times equal to the DTCs stored in the memory. If no DTCs are stored, the BCM does not flash the fasten belts indicator or sound the chime. The BCM flashes and sounds the first DTC with the lowest number, pauses, then continues with the next DTC with a higher number until all the DTCs are read. Once all the DTCs are read, the BCM repeats this sequence 3 times.

If there are DTCs in the memory, record the DTCs and refer to Identifying Diagnostic Trouble Codes. Identifying the Diagnostic Trouble Codes
