Restore Full Electrical Control to Your GM Vehicle
Is your Chevrolet, GMC, Buick, or Cadillac suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. This replacement BCM, part number 22820314, is the definitive solution to restore your vehicle’s functionality and your peace of mind.
From the Diagnostic Bay
We recently had a 2014 Chevy Traverse in the shop with the weirdest electrical gremlins. The radio would turn on by itself, the dome lights would flicker, and the key fob worked only half the time. The customer was convinced the vehicle was haunted. After hours of chasing wires and checking grounds, we traced it all back to an internally failing BCM. A simple swap with a VIN-programmed unit like this one had the customer back on the road in under an hour, with all electrical systems operating perfectly. It’s a common failure point that can mimic a dozen other problems.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a failing Body Control Module is the likely culprit:
- ✔ Erratic power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, not turning on, or flickering.
- ✔ The horn honking randomly or failing to work when pressed.
- ✔ Security system malfunctions, including false alarms or the inability to arm/disarm the system.
- ✔ A “Service Theft Deterrent System” message appearing on the dashboard.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, often starting with ‘U’.

Important Installation Information
While this module is programmed for plug-and-play installation, certain vehicle systems may require a recalibration or sync procedure after the new BCM is installed. Please be aware of the following potential steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified automotive technician for vehicle-specific procedures.
Frequently Asked Questions
Is this BCM really plug-and-play?
Yes, it is. We program the module using your vehicle’s VIN, so it arrives ready to be installed without any additional programming. However, as noted, some models may require a simple relearn procedure for systems like the airbags or brake pedal sensor after installation.
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 ship your order until we receive this information, as the programming is specific to your vehicle.
My original part number is 22915542. Will this part work?
Absolutely. This BCM is a direct replacement for both 22820314 and 22915542. It will function identically to the original part.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional diagnostic scan tool. Most basic code readers cannot perform these functions.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module without any penalty.
