Body Control Module (BCM) Programming/RPO Configuration: Notes

WARNING: This page is about a different car, the 2005 Saturn L300. However, it is still accessible from the selected car via links, so may be relevant.
  1. The body control module (BCM) must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of 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 ON position.
    • The data link connector (DLC) is accessible.
    • All disconnected modules and devices are reconnected before programming.
  2. To setup a new BCM, use the Tech 2 in conjunction with the Saturn Service Stall System. Refer to Service Programming System (SPS) in Programming.
  3. If the BCM fails to accept the program, perform the following steps:
    • Inspect all BCM connections.
    • Verify that the scan tool has the latest software version.
