Tired of Chasing Electrical Gremlins?
Are you dealing with a vehicle that seems to have a mind of its own? Flickering lights, power windows that won’t cooperate, a security system that randomly activates, or a stubborn no-start condition can be incredibly frustrating. These aren’t just annoyances; they’re often symptoms of a failing Body Control Module (BCM)—the electronic nerve center of your vehicle. Replacing it used to mean an expensive tow to the dealership for parts and programming. We offer a better way.
This is a direct-fit replacement GM BCM 22915542, professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. We load the latest GM-certified software, ensuring that when it arrives, it’s ready for installation. This simple, effective solution gets you back on the road quickly, saving you hundreds in dealership programming fees and diagnostic time.
A Technician’s Notebook: The Traverse with a Ghost
I remember a 2015 Chevy Traverse that came into my bay with a laundry list of bizarre complaints. The owner said the radio would cut out, the dome lights would flicker while driving, and sometimes the power liftgate wouldn’t respond. He’d already replaced the battery and checked the alternator. My initial scan showed a slew of ‘Lost Communication’ codes (U-codes), pointing in a dozen different directions. This is a classic sign of a network issue, and the BCM is the network’s traffic controller. Instead of spending hours chasing individual component failures, we went straight to the source. Swapping in a pre-programmed BCM like this one solved every single issue instantly. It’s a reminder that a failing BCM doesn’t just cause one problem; it creates system-wide chaos.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. A failing module can often trigger codes like U0140 (Lost Communication With Body Control Module) or various B-codes (Body codes) related to specific functions.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The anti-theft or security system light flashing, preventing the car from starting.
- ✔ Inconsistent operation of the radio or infotainment system.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
- ✔ Wipers or climate control functions working intermittently.
A Straightforward Guide to Installation
Installing your new GM BCM 22915542 is a manageable job for a DIY enthusiast or a quick task for any professional mechanic. The location is typically under the driver’s side dash (LH dash) or in the center dash area for vans.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On models like the Impala, Traverse, and Acadia, it’s usually mounted to the left of the steering column. On Express and Savana vans, it’s often found in the center dash area. A quick search for your specific model will confirm the location.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New Module: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses. Ensure they click into place.
- Reconnect Battery & Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While this module is VIN-programmed for your vehicle, some integrated safety systems may require a recalibration or sync procedure after installation. This is standard for modern vehicles.
- 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 computer.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light operation and traction control system function.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this BCM truly plug-and-play?
Yes, it comes pre-programmed to your VIN. In most cases, you can simply install it. However, as noted, some vehicles may require additional sync procedures for systems like the airbags or brakes, which require a professional scan tool.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship the module without it.
Will this fix my ‘Service StabiliTrak’ message?
A failing BCM can sometimes cause traction or stability control warnings. If the BCM is the root cause, this part should resolve it. However, StabiliTrak issues can also be caused by wheel speed sensors or other components, so proper diagnosis is key.
How do I know if this GM BCM 22915542 is the right part?
Please match the part number from your original module to 22915542 or 22820314. You can also use the detailed fitment list provided on this page to confirm compatibility with your vehicle’s year, make, and model.
