Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet, GMC, Buick, or Cadillac experiencing a host of bizarre electrical issues? From flickering lights and malfunctioning power windows to a vehicle that won’t start, the root cause is often a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and seemingly unrelated problems. This pre-programmed GM Body Control Module 22915542 is the definitive solution, designed to restore your vehicle’s functionality and get you back on the road with confidence.
Unlike a standard replacement part from a dealership or parts store, this module arrives at your door ready for installation. We take your vehicle’s VIN and flash the module with the latest, most stable software directly from GM. This critical programming step ensures that the BCM communicates perfectly with your vehicle’s other systems, eliminating the need for an expensive trip to the dealer for programming. It’s a true plug-and-play solution for the savvy DIYer or professional technician.
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.
- ✔ The security system or anti-theft light flashing, preventing the car from starting.
- ✔ Key fob not being recognized or failing to lock/unlock the doors.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Wipers turning on by themselves or not working when commanded.
- ✔ HVAC (heating and air conditioning) controls being unresponsive.
From the Diagnostic Bay
We had a 2015 Chevy Traverse in the shop that was driving its owner crazy. The radio would randomly change stations, the dome light would flicker while driving, and the power locks seemed to have a mind of their own. The owner had already replaced the battery and checked every fuse imaginable. After connecting our diagnostic scanner and seeing a flood of communication errors between various modules, we pinpointed the BCM. Instead of a costly dealer replacement, we installed a pre-programmed module just like this one. In under an hour, every single electrical gremlin was gone. It’s a testament to how critical this single component is to the vehicle’s overall health.

Check the fitment list to confirm compatibility with your exact model.
Installation and Post-Install Procedures
Installation is typically straightforward, involving locating the old BCM (often under the driver’s side dash), disconnecting the battery, swapping the electrical connectors to the new module, and reconnecting the battery. However, on modern vehicles, a few additional steps, known as relearn procedures, may be required.
Important Note: While this module is programmed to your VIN, your vehicle’s other modules may need to sync with the new BCM. The following procedures may be necessary and require a professional-grade diagnostic scan tool:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure proper brake light operation and stability control function, a brake pedal position sensor recalibration might be needed.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about performing these procedures.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the BCM with the correct software and settings for your specific vehicle. This ensures compatibility with your engine, transmission, and factory-installed options, making the installation process as smooth as possible.
Is this a plug-and-play part?
Yes, this BCM is designed to be as plug-and-play as possible because we program it to your VIN before shipping. However, as with any major electronic module replacement, some vehicles may require additional ‘relearn’ procedures for systems like the airbags or brakes, which require a professional scan tool.
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 ‘Service Theft Deterrent System’ message?
A faulty BCM is a very common cause of issues with the anti-theft and security systems. While not a guarantee for every case, replacing a failing BCM with our pre-programmed unit often resolves these types of error messages and no-start conditions.
Where is the BCM located on my vehicle?
The location varies, but on most compatible models like the Traverse, Acadia, and Impala, the BCM is located on the driver’s side, up under the dashboard near the steering column. On Express and Savana vans, it’s typically found in the center dash area.
