Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security systems, and the instrument cluster.
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the specific software and settings for your car’s exact options and features. This makes the module ready to install out of the box and avoids the need for expensive dealer programming.
Is this part difficult to install?
The physical replacement of the BCM is typically straightforward, often located under the dash. However, some models may require additional electronic relearn procedures after installation, such as for the airbag or brake systems, which may require a professional scan tool.
What happens if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the airbag system’s computer (SDM). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
