Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and more.
Do I need to program this module?
No! We handle the programming for you. Simply provide your vehicle’s VIN during or after your purchase, and we will flash the module with the latest GM software for your specific vehicle before shipping.
How do I find my original BCM part number?
The part number is printed on a sticker on the case of your original BCM. Its location varies by model but is often under the dash on the driver’s side or in the center console area. Verifying your part number is the best way to ensure compatibility.
What if my airbag light is on after installation?
If the airbag light is on, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade diagnostic tool.
Is this a simple plug-and-play installation?
Because we program it to your VIN, it is as close to plug-and-play as possible. However, as with any module replacement, some vehicles may require additional relearn procedures for systems like the brake sensor or airbags, as noted in the description.
Do I need to return my old part?
No, there is no core charge for this part. You can keep your original module.
