Restore Full Functionality to Your Vehicle’s Electronics
Are you battling frustrating electrical issues in your GM vehicle? Flickering lights, unresponsive power windows, or strange warning messages on your dash are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to the security system. When it fails, it can create a cascade of seemingly unrelated problems that can be difficult to diagnose.
This replacement Body Control Module, part number 22915542 (also compatible with 22820314), is the definitive solution to these electrical gremlins. We take the guesswork and high dealership costs out of the equation. Simply provide your vehicle’s VIN during checkout, and our experts will program the module with the latest official GM software specific to your car or truck. This ensures a seamless installation process, getting you back on the road with confidence.
From the Diagnostic Bay
We had a 2015 Chevy Traverse come in that was driving the owner crazy. The dome lights would randomly stay on, draining the battery overnight. The driver’s side power window worked only when it wanted to, and the key fob’s remote start was completely dead. The customer had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a complex and expensive rewiring job, we installed a VIN-programmed BCM. Within an hour, all the phantom electrical issues were gone. The lights worked perfectly, the window responded instantly, and the remote start fired right up. It’s a perfect example of how one single component can restore a vehicle’s comfort and convenience features.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working headlights, taillights, or interior lights.
- ✔ Power windows, door locks, or mirrors behaving erratically or not at all.
- ✔ The vehicle’s security system or anti-theft light malfunctioning.
- ✔ Key fobs that stop working for locking, unlocking, or remote start.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warning lights appearing on the instrument cluster (e.g., airbag, ABS).
- ✔ Horn, wipers, or other accessories activating unexpectedly.
The Advantage of a Pre-Programmed GM BCM 22915542
Traditionally, replacing a BCM required towing your vehicle to a dealership for expensive programming with specialized tools. Our service eliminates that step entirely. By programming the module to your VIN before it ships, we provide a component that is ready for installation right out of the box. This saves you significant time, money, and hassle. We load the most current software available from GM, ensuring optimal performance and compatibility with your vehicle’s existing systems.
Installation and Post-Install Procedures
Physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, on modern vehicles, certain systems may need to be re-synchronized after the BCM is replaced. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s supplemental restraint module.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct operation of the brake lights and stability control systems.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and other interior accessories. It’s the brain for your car’s body electronics.
Why do you need my VIN to program the BCM?
Every vehicle has a unique configuration of options and features. Programming the BCM with your specific Vehicle Identification Number (VIN) ensures the module is loaded with the correct software and calibrations to work perfectly with your exact model, trim, and options.
Is this part difficult to install?
The physical replacement is often simple, usually located under the dash. However, post-installation procedures like an airbag system sync or brake pedal relearn may be required and necessitate a professional-grade diagnostic tool.
What happens if the airbag light comes on after I install it?
This indicates the new BCM needs to be electronically introduced to the airbag system. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
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 GM BCM 22915542 fit my vehicle?
This module fits a wide range of GM vehicles including the Impala, Traverse, Acadia, Enclave, CTS, Savana, and Express vans from approximately 2013-2018. Please review the detailed fitment list on this page to confirm compatibility.
