Is your GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and frustrating electrical issues. Don’t let these problems leave you stranded or drain your wallet at the dealership. We have a reliable, straightforward solution.
This is a direct-replacement Body Control Module for a wide range of 2006-2013 GM vehicles, including popular models like the Impala, Tahoe, Acadia, and Express/Savana vans. The best part? It arrives at your door fully programmed to your vehicle’s specific VIN. Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates, ensuring it’s ready for installation right out of the box. This eliminates the need for expensive dealer-only programming tools and procedures.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system faults or alarm sounding unexpectedly.
- ✔ Wipers or radio behaving strangely.
- ✔ A/C and climate control issues.
- ✔ Instrument cluster warning lights (like the airbag light) illuminating for no reason.
- ✔ A no-start or no-crank condition where the engine won’t turn over.
From the Diagnostic Bay
We had a 2011 Chevy Traverse come in that was driving the owner crazy. The radio would randomly change stations, the dome light would flicker while driving, and occasionally the power liftgate would refuse to open. The owner had already replaced the battery and checked all the fuses. After running diagnostics, we found no specific codes pointing to a single component, just a lot of communication errors. This is a classic sign of a BCM failure. Instead of a complex wiring repair, a simple swap with a VIN-programmed BCM like this one resolved all the gremlins at once. The customer was thrilled to have their car back to normal without a massive repair bill.

Installation and Post-Install Notes
While this module is designed for a straightforward swap, some vehicles may require minor post-installation procedures to ensure all systems communicate correctly. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you the time, cost, and hassle of a dealership visit.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the module correctly for your specific car or truck.
Is this a guaranteed fix for my vehicle’s electrical problems?
This Programmed GM Body Control Module will fix issues directly caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What happens if my airbag light turns on after I install it?
This can happen on some models. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module.
