Is Your Vehicle Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster. When the BCM begins to fail, it can create a cascade of bizarre and frustrating symptoms that can be difficult to diagnose. If you’re dealing with unpredictable electrical issues, a faulty BCM is often the culprit.
Why Choose Our Pre-Programmed GM Body Control Module?
Replacing a BCM isn’t as simple as swapping the part. A new module must be programmed specifically to your vehicle’s Vehicle Identification Number (VIN) and its unique set of options. Traditionally, this required an expensive trip to the dealership for programming after installation. Our solution eliminates that step entirely. We flash this genuine GM Body Control Module with the latest software updates from GM, using the VIN you provide. It arrives at your door ready for a straightforward installation, saving you time, money, and hassle.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning keyless entry or push-to-start systems.
- ✔ False alarms from the security system or a ‘Service Theft System’ message.
- ✔ Inoperative windshield wipers or climate controls.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Communication errors with other vehicle modules.
Installation and Post-Install Considerations
Installation is typically a plug-and-play process. Locate your existing BCM (often found in the driver’s or passenger’s side dash area), disconnect the battery, carefully unplug the electrical connectors, and swap the module. While our programming handles the majority of the setup, some vehicles may require additional syncing procedures after the new module is installed.
Post-Installation Procedures:
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system. This is only needed if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic body functions not related to the engine, such as power windows, locks, lights, security system, and wipers.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is specific to your exact vehicle.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical installation is straightforward. It involves disconnecting the battery and swapping the module. The main benefit of our service is that the complex software programming is already done for you.
Do I need to send my old BCM back?
No. This part has no core charge. You can keep your original module.
What if my airbag light is on after installation?
This indicates the new BCM needs to be synced with your vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a shop with a professional diagnostic tool to resolve this.
Does this part fit my vehicle?
This module fits a wide range of GM vehicles including the Impala, CTS, Savana, Traverse, Acadia, Express, Captiva Sport, and Enclave from approximately 2013-2019. Please verify your part number (22820314 or 22915542) and check the detailed fitment list on this page.
