2005 Saturn Relay AWDFACTORY OEM SERVICE PROCEDURE

BCM Programming

WARNING: This page is about a different car, the 2005 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Use extreme care when verifying both the VIN and Odometer reading that is set in the service BCM. Once the VIN and Odometer are set in the replacement BCM it is impossible to change them, and if there is a mismatch, the part will be rendered useless.

To setup a new replacement BCM select Vehicle Control Systems, then navigate to Computer/Integrating Systems, once in the Computer/Integrating Systems menu select Module Replacement/Setup and follow the instructions on the scan tool. After the setup procedure it is necessary to perform the Remote Start setup procedure and BPP Sensor Calibration procedure. Refer to the Important's below for further information.

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.
