Restore Full Electronic Control to Your GM Vehicle
Are you battling a storm of strange electrical problems in your car, truck, or SUV? Flickering interior lights, power windows with a mind of their own, a security system that won’t cooperate, or random warning lights on the dash are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread and frustrating issues. This is the reliable, straightforward solution to get your vehicle back to normal without an expensive trip to the dealership.
A Technician’s Notebook: The Case of the Haunted Equinox
I remember a 2009 Chevy Equinox that came into my bay with a list of complaints that seemed completely unrelated. The owner said the radio would turn off randomly, the driver’s side power lock wouldn’t work, and the dome light would stay on, draining the battery overnight. He had already replaced the battery and checked fuses, but the problems persisted. A quick scan showed a flurry of communication codes, specifically a U0140 (Lost Communication With Body Control Module). This pointed directly to the BCM. Instead of a dozen separate issues, it was one single point of failure. We installed a VIN-programmed BCM, and instantly, every single electrical gremlin was gone. It’s a perfect example of how a failing 2008 – 2012 GM Body Control Module can wreak havoc.
Is Your Vehicle Experiencing These Electrical Gremlins?
A failing BCM doesn’t always trigger a check engine light. Instead, look for these common symptoms that indicate the BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Warning lights for the airbag, ABS, or traction control system appearing without a clear cause.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or U0100.
- ✔ A persistent battery drain that you can’t trace to another source.
The Simple, Reliable Solution: VIN-Programmed and Ready to Install
Forget about scheduling a dealership appointment and paying high labor costs for programming. We handle the hard part for you. When you purchase this 2008 – 2012 GM Body Control Module, you simply provide us with your vehicle’s VIN. Our experts will then program the module with the latest, most stable software directly from GM. This ensures it communicates perfectly with your vehicle’s other systems right out of the box. Plus, there is no core charge, so you can keep your old part without the hassle of shipping it back.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: The location varies by model. Common spots are behind the driver’s side or passenger’s side of the dashboard, under the steering column, or in the center console area. (Refer to the fitment list for typical locations).
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. Ensure they click into place.
- ✔ Reconnect Power: Reconnect the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. Note that for some vehicles, additional relearn procedures for the brake pedal position sensor or airbag system may be required if warning lights appear. A professional scan tool is needed for these specific procedures.

Frequently Asked Questions
Frequently Asked Questions
Do I need to get this 2008 – 2012 GM Body Control Module programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you time and money.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add this in the notes section at checkout or reply to your order confirmation email.
What if my airbag light comes on after installation?
In some cases, the new BCM needs to be synced with the airbag’s Supplemental Restraint System (SRS) module. This is a procedure called ‘Setup SDM Primary Key in BCM’ and requires a professional-grade scan tool to complete.
Is a ‘Brake Pedal Position Relearn’ always required?
Not always, it depends on the specific model and year. If you notice issues with your brake lights or traction control system after installation, this recalibration procedure may be necessary.
What if my original part number is not on your list?
Our list of compatible part numbers is extensive. If you don’t see your exact number, please contact us with your VIN and original part number. We can verify compatibility for you.
