BODY CONTROL MODULE (BCM) PROGRAMMING/RPO CONFIGURATION

The procedures below are designed to set-up the body control module (BCM) correctly during BCM related service. Before you start, read these procedures carefully and completely.

IMPORTANT: The following procedures must be followed:
1. Programming the BCM.
2. Programming Theft Deterrent System Components.
3. Program Key Fobs

Programming the BCM

IMPORTANT:
- The BCM can be programmed using only Pass-Thru procedure.
- After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again.

Pass-Thru programming allows the scan tool to remain connected to the terminal and to the vehicle throughout the programming process. The vehicle must be in close proximity to the terminal while using Pass-Thru. Refer to Service Programming System (SPS) in Programming and Setup for more information.

Programming Theft Deterrent System Components
Perform the Programming Theft Deterrent System Components in Theft Deterrent after successfully finishing the Setup New BCM procedure. If the Programming Theft Deterrent System Components in the Theft Deterrent procedure is not performed after a BCM replacement, one of the following conditions will occur:
- The vehicle will not be protected against theft by the PASSLOCK system.
- The engine will not crank or start.

Program Key Fobs
Refer to Transmitter Programming in Keyless Entry for the proper procedure.

IMPORTANT: After programming, perform the following to avoid future misdiagnosis:
1. Turn the ignition OFF for 10 seconds.
2. Connect the scan tool to the data link connector.
3. Turn the ignition ON, with the engine OFF.
4. Use the scan tool in order to retrieve history DTCs from all modules.
5. Clear all history DTCs.
