Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing a host of frustrating and seemingly unrelated electrical issues in your GM car, truck, or SUV? From flickering lights and malfunctioning power windows to a vehicle that refuses to start, the culprit is often a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create chaos. This replacement GM Body Control Module 22820314 is the definitive solution to restore your vehicle’s proper operation and your peace of mind.
Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this BCM arrives at your door fully programmed to your specific vehicle. We use your Vehicle Identification Number (VIN) to flash the module with the latest, most stable software directly from GM. This ensures perfect compatibility and function right out of the box, saving you hundreds of dollars in programming fees and vehicle downtime.
We had a 2015 GMC Acadia come into the shop with a classic case of BCM failure. The customer complained of the radio turning on by itself, intermittent power lock failure, and a parasitic battery drain that left them stranded twice. After confirming the BCM was the source of the electrical gremlins, we installed one of our pre-programmed units. The installation was straightforward, and because it was already flashed to the vehicle’s VIN, all the strange issues vanished immediately. The customer was thrilled to have their vehicle back to normal without the high cost and long wait associated with a dealership repair.
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 engaging randomly or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when needed.
- ✔ False warning lights appearing on the instrument cluster (e.g., ABS, Airbag, Check Engine).
- ✔ Rapid battery drain while the vehicle is parked.
- ✔ Complete no-start condition where the engine won’t crank.

Post-Installation Information
While our programming handles the critical setup, some vehicles may require minor post-installation procedures, known as relearns. These are simple syncs that can be performed with a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control system function.
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 variety of non-engine-related electronic functions. This includes power windows, locks, lights, wipers, the security system, and more.
How do I know if my BCM is failing?
Common signs include multiple, unrelated electrical issues happening at once, such as flickering lights, malfunctioning power accessories, random alarm activation, and parasitic battery drain. A professional diagnosis is the best way to confirm.
Is this part difficult to install?
The physical replacement of the BCM is typically straightforward for someone with moderate mechanical skill. It’s often located under the dashboard. Since our module comes pre-programmed, you skip the most difficult part of the job, which is the software setup.
Why do you need my VIN?
Your vehicle’s 17-digit VIN is essential for us to load the exact, correct software and settings for your specific model, year, and options. This ensures the BCM works perfectly as soon as it’s installed.
What happens if my airbag light comes on after installation?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
