Body Control Module (BCM) Programming/RPO Configuration: Notes
WARNING: This page is about a different car, the 2004 GMC Safari and 2004 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
If any module is replaced, the module must be programmed with the regular production options (RPO) prior to performing the Passlock Learn procedure. The Techline Terminal automatically selects the RPO codes based on the vehicle identification number (VIN).
- 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 data link connector (DLC) is accessible.
- All accessories are turned OFF.
- Follow the service programming system (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 DLC, scan tool and Techline Terminal connections.
- Insure that the battery is fully charged.
- Verify that the SPS Techline Terminal and scan tool have the latest software version.
- Inspect all BCM connections.
