Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing bizarre electrical issues in your 2007-2012 GMC Acadia or another compatible GM vehicle? A failing Body Control Module (BCM) is often the culprit behind a host of frustrating problems, from malfunctioning power accessories to no-start conditions. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can make your car feel unpredictable and unreliable. This replacement Body Control Module is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN.
From the Diagnostic Bay
We had a 2011 GMC Acadia come into the shop with a laundry list of complaints. The power liftgate would open on its own, the radio would randomly shut off, and the security light was always flashing. The owner had been to two other shops that couldn’t pinpoint the issue. After running diagnostics, we traced all the communication errors back to a faulty BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The install took less than an hour, and all the electrical gremlins were gone. The customer was thrilled to have their vehicle back to normal without the dealership hassle and expense.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Flickering or inoperative interior and exterior lights.
- ✔ Erratic behavior from the instrument cluster gauges or warning lights.
- ✔ Problems with the vehicle’s security system or remote keyless entry.
- ✔ The engine cranks but refuses to start due to anti-theft system communication failure.
- ✔ Unresponsive climate control functions.
- ✔ Communication error codes when scanned with a diagnostic tool.
The Plug-and-Play Solution: A Pre-Programmed Acadia Body Control Module
Replacing a BCM used to mean a mandatory, expensive trip to the dealership for programming. Our process eliminates that step. When you purchase this Acadia Body Control Module, you provide us with your vehicle’s VIN. Our technicians then flash the module with the correct software and vehicle-specific calibration files. It arrives at your door ready to be installed, saving you significant time and money. This is a direct-fit replacement for part number 15819552 and a wide range of other GM part numbers, ensuring complete compatibility.
Installation and Post-Install Notes
Installation is straightforward for a DIYer with moderate experience or any professional technician. After installation, some vehicles may require additional simple procedures for full system integration:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This is a security feature that requires a professional scan tool to sync 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 function of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages your vehicle’s non-engine related electronics. This includes power windows, door locks, interior/exterior lights, the security system, wipers, and more.
Does this module require programming at a dealership?
No. We pre-program this module to your vehicle’s specific VIN before shipping it to you. It arrives ready for installation, saving you the time and expense of a dealer visit.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Is this compatible with other vehicles besides the GMC Acadia?
Yes. This BCM fits a very wide range of GM vehicles, including models from Chevrolet, Buick, Cadillac, Saturn, and more. Please check the extensive part number list and fitment chart on this page to confirm compatibility with your vehicle.
What if my airbag light comes on after I install it?
This is a normal security handshake procedure. A mechanic with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ function to sync the modules and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
