Are you chasing electrical gremlins in your GM truck or SUV? Flickering lights, a radio that has a mind of its own, or random warning messages like “Service StabiliTrak” can be incredibly frustrating. As a technician with over two decades of experience, I’ve seen these exact issues countless times. More often than not, the culprit is a failing Body Control Module (BCM), the central nervous system for your vehicle’s electronics.
This isn’t just an inconvenience; a faulty BCM can affect your vehicle’s security system, power windows, and even its ability to start. Don’t let a failing module leave you stranded or dealing with unpredictable behavior. We offer a reliable and straightforward solution: a replacement BCM, pre-programmed specifically for your 2012-2013 Suburban 2500 BCM and a wide range of other GM vehicles. Simply provide your VIN during checkout, and we’ll flash the module with the latest GM software before it even leaves our facility. This eliminates the need for expensive dealership programming, saving you time and money.
A Technician’s Notebook
I remember a 2013 Silverado 2500 that came into the shop with a bizarre set of symptoms. The owner said sometimes the dome lights wouldn’t turn off, the key fob worked intermittently, and occasionally, the truck wouldn’t start at all—just a click. He had already replaced the battery. A scan showed a handful of communication codes (U-codes) pointing to the BCM. After confirming power and grounds were good at the module, we knew the internal logic had failed. Swapping in a pre-programmed BCM like this one solved every single issue instantly. It turned a potentially week-long diagnostic nightmare into a one-hour fix.
Common Signs of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or security system acting up.
- ✔ The horn sounding randomly or not working at all.
- ✔ Warning lights on the dashboard, such as for the airbag or traction control system.
- ✔ Communication error codes, often in the U-series (e.g., U0140, U0155).
- ✔ A no-start condition where the engine doesn’t crank, but the battery is good.
Your Straightforward BCM Installation Guide
Replacing your BCM is a manageable task for a confident DIYer. This pre-programmed module makes the process much simpler.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most compatible models, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reinstall any panels you removed, then reconnect the negative battery terminal. Start the vehicle and test all functions: lights, windows, locks, radio, etc.
Important Post-Installation Steps
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on 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.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly by vehicle.

Frequently Asked Questions
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, please send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information to program the module correctly.
Is this a simple plug-and-play installation?
For most functions, yes. Because we pre-program the module to your VIN, it eliminates the most difficult step. However, as noted above, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may 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.
What if the part number on my old module is 22737275?
This module is a fully compatible, direct replacement for part numbers 22737275, 22846365, and 22846364. As long as your vehicle is on the fitment list, it will work perfectly.
Will this fix my specific problem?
This BCM will fix issues caused by a faulty module. While the symptoms listed are very common for BCM failure, it’s always best to have a proper diagnosis performed to rule out other potential causes like wiring or sensor issues.
