Restore Full Functionality to Your GM Truck or SUV
Are you chasing down frustrating electrical gremlins in your truck? Intermittent wipers, flickering lights, a dead HVAC system, or power windows with a mind of their own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of problems that are difficult to diagnose. This OEM-quality Body Control Module, part number 22860591, is the definitive solution for your 2007-2013 GM vehicle, arriving pre-programmed to your specific VIN for a true plug-and-play repair.
A Technician’s Notebook: The Silverado with a Ghost
I had a 2011 Silverado 2500 in my bay last month that was driving the owner crazy. The radio would shut off randomly, the A/C blower worked only when it wanted to, and the security light would flash, sometimes preventing the truck from starting. The owner had already replaced the battery and checked the main grounds. After hooking up my scanner, I found a handful of communication codes and a specific BCM internal failure code. These symptoms are something I’ve seen hundreds of times. We installed one of our VIN-programmed BCMs, and in less than 10 minutes, every single issue was gone. This isn’t just a part replacement; it’s a permanent fix that restores the vehicle’s reliability without a costly trip to the dealer.
Is Your Truck Exhibiting These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your Body Control Module is the culprit. This is especially true if you see a 2013 Sierra Denali 2500 BCM fault code.
- ✔ Unresponsive or erratic HVAC controls, including a blower motor that won’t turn on or off.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Power windows, door locks, or interior/exterior lights that work intermittently or not at all.
- ✔ Security system malfunctions, causing no-start conditions, stalling, or misfires.
- ✔ Poor ground symptoms or a cluster of seemingly unrelated electrical issues.
- ✔ Communication errors with other modules on the vehicle network.
A Straightforward Guide to BCM Installation
One of the best features of this module is its simple installation. You don’t need to be a master mechanic to get your truck running right again. The entire process typically takes less than five minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most GM trucks and SUVs, the BCM is located under the driver’s side dashboard, near the steering column. It’s often mounted to a bracket with a few connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Unbolt or unclip the old module and set it aside. Mount the new module in its place.
- Connect and Test: Securely plug the connectors into your new, pre-programmed BCM. Reconnect the battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC system.
Important Note: In some cases, particularly if you had an airbag light on, you may need a professional scan tool to perform a ‘Setup SDM Primary Key in BCM’ function to sync the new module with the airbag system. Also, it’s always a good practice to check the main ground connections in the area during replacement to prevent future issues.

Frequently Asked Questions
Why is a VIN-programmed BCM better?
Our BCMs are programmed to your vehicle’s specific VIN before shipping. This ensures all your vehicle’s original options work correctly and saves you from a mandatory, expensive programming session at a dealership. It’s a true plug-and-play solution.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a very common cause of the B1001 code. Replacing it often resolves the issue. However, after installation, you may need a bi-directional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light, as it’s a required security handshake between the modules.
What if this part doesn’t solve my problem?
While this module fixes the vast majority of the symptoms listed, complex electrical issues can sometimes have other causes, like a bad ground or wiring problem. We stand by our products with a one-year warranty and have expert technicians available to help you with your diagnosis.
Is this a difficult part for a DIYer to replace?
Not at all. This is one of the easier modules to replace. It’s typically located under the dash and held in by simple clips or bolts. With basic hand tools, most people can swap the module in under 10 minutes.
Do I need to send my old BCM back?
No, there is absolutely no core charge for this part. You can keep your old module without any hassle or extra fees.
