Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, door locks, interior and exterior lighting, wipers, and the climate control system.
Is programming absolutely necessary for this part?
Yes. A BCM will not function correctly without being programmed to your vehicle’s specific Vehicle Identification Number (VIN). Our service handles this for you, so the part arrives ready for installation without any extra steps.
How difficult is the installation?
For most supported models, the BCM is located under the steering column or center dash and is held in by a few clips or bolts. The physical swap typically takes less than 15 minutes. Simply disconnect the battery, unplug the old module, plug in the new one, and reconnect the battery.
Will this fix my airbag light?
A faulty BCM can cause the airbag light to come on. While this module will fix the BCM-related cause, the airbag system (SDM) may need to be re-synced to the new BCM using a professional scan tool to turn off the light. This is a common procedure known as ‘Setup SDM Primary Key in BCM’.
What if I still have problems after installation?
Our pre-programming resolves the most common issues. However, some vehicles may require a ‘Brake Pedal Position Relearn’ or other minor recalibrations with a scan tool. If you have any questions, our expert support team is here to help guide you.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module without the hassle of returning it.
