Restore Full Electronic Functionality to Your GM Vehicle
Is your Chevrolet, GMC, or Cadillac suffering from bizarre electrical problems? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable issues. This direct-replacement BCM, part number 22915542 (also interchangeable with 22820314), is the definitive solution to restore order and reliability to your vehicle.
The Simple, Reliable Solution: A Programmed GM BCM
Don’t waste time and money at the dealership with expensive programming fees or risk using a junkyard part with an unknown history. We take the guesswork out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program this module with the latest GM software specific to your car or truck. It arrives at your door ready for a straightforward installation, getting you back on the road quickly and confidently.
From the Diagnostic Bay
We recently had a 2014 Chevy Traverse in the shop with a laundry list of strange symptoms. The owner reported that the radio would sometimes not turn off after removing the key, the driver’s side power window worked intermittently, and the anti-theft light would flash randomly while driving. Standard diagnostics pointed to a communication breakdown. Instead of a complex wiring issue, the root cause was a failing BCM. Swapping it with a pre-programmed module like this one resolved all the issues in under an hour. It’s a common failure point that often presents as multiple, unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Malfunctioning windshield wipers or washers.
- ✔ Vehicle security system or keyless entry problems.
- ✔ False warnings on the dashboard, such as ‘Service Airbag’ or ‘Service StabiliTrak’.
- ✔ Rapid battery drain while the vehicle is parked.
Installation and Post-Install Procedures
Installation is typically straightforward, involving disconnecting the battery, locating the old BCM (usually under the driver’s side dash), and swapping the modules. However, due to the integration with other vehicle systems, a couple of additional steps may be required after the new module is installed.
Important Note: While this module is delivered programmed, certain security and safety systems may need to be re-synced to the new BCM.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. This is the key benefit of our service. We program the BCM to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you a trip to the dealership and their associated programming fees.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What happens if my airbag light is on after I install the new BCM?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A technician with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is this a simple plug-and-play part?
For most functions, yes. The VIN programming handles the majority of the setup. However, as mentioned, post-installation procedures like the airbag system sync or brake pedal position relearn may be necessary depending on your specific vehicle.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. If you are experiencing any of the common symptoms listed, there is a very high probability that this part will resolve the problem. Proper vehicle diagnosis is always recommended.
