Body Control Module (BCM) Programming/RPO Configuration: Notes
WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
Important: If the module is replaced, programming the module with the proper RPO configurations must be done prior to performing the Passlock Learn procedure.
- The BCM must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options. If the BCM is not properly configured with the correct RPO codes the BCM will not control the features properly. Ensure that the following conditions exist in order to prepare for BCM programming:
- The battery is fully charged.
- The ignition switch is in the RUN position.
- The DLC is accessible.
- All disconnected modules and devices are reconnected before programming.
- Follow the SPS instructions on the Techline Terminal and scan tool to program the BCM.
- If the BCM fails to accept the program, perform the following steps:
- Inspect all BCM connections.
- Verify that the SPS Techline Terminal and scan tool have the latest software version.
