Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
BCM Programming
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 select the applicable options, then select Module Setup, then select Body Control Module on the scan tool. If the scan tool can communicate with the BCM that is being replaced, select BCM Copy and Flash. If the scan tool is unable to communicate with the BCM that is being replaced, select BCM Setup. After the setup procedure it is necessary to perform the Remote Start setup procedure. Refer to the Notes 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.
