Restore Full Electrical Function to Your GM Truck
Are you chasing down frustrating electrical gremlins in your truck? Intermittent wipers, flickering lights, a dead HVAC blower, 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 seemingly unrelated problems. This OEM-quality module, interchangeable with part number 22860591, is the definitive solution for your 2011 Sierra 2500 BCM and a wide range of other GM trucks and SUVs from 2007-2013.
We take the guesswork and high dealership costs out of the equation. Each module is expertly programmed to your vehicle’s specific VIN before shipping. This ensures it communicates perfectly with your truck’s other systems right out of the box, eliminating the need for expensive scan tools or a trip to the dealer for programming. Get your truck back to full operational health quickly and confidently.
Case Study: A Tricky Diagnosis
I recently had a 2012 Silverado 1500 in the shop that was driving its owner crazy. The radio would randomly shut off, the driver’s side power lock was dead, and the security light would flash, sometimes preventing the truck from starting. The owner had already replaced the battery and checked every fuse. After hooking up my scanner, I saw a handful of communication codes (U-codes) pointing to the BCM. Instead of a complex wiring issue, it was a classic internal BCM failure. We swapped in a VIN-programmed module like this one, and in less than 10 minutes, every single issue was resolved. It’s a reminder that sometimes the simplest fix is the right one, provided you have a quality, correctly programmed part.
Is Your GM Truck Showing These Telltale Signs?
- ✔ The air conditioning or heater blower motor works intermittently or not at all.
- ✔ Power windows, door locks, or interior/exterior lights are behaving erratically.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Setup SDM Primary Key Mismatch).
- ✔ Your vehicle’s security system is malfunctioning, causing no-start or stalling conditions.
- ✔ You’re seeing multiple communication or body-related diagnostic trouble codes.
- ✔ Wipers won’t turn on, or won’t park in the correct position.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New Module: Seat the new, VIN-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, wipers, locks, windows, and HVAC to confirm the repair.
Post-Installation Note: In some cases, particularly if the airbag light was on, a ‘Setup SDM Primary Key in BCM’ procedure may be needed using a bi-directional scan tool to sync the new BCM with the airbag system. Additionally, a Brake Pedal Position relearn might be required. These are simple procedures for any professional shop if needed.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows and locks, wipers, security system, and climate controls.
Do I need to have a dealer program this module?
No. We pre-program the module to your vehicle’s VIN before it ships. This makes it a plug-and-play solution, saving you the time and expense of a dealership visit for programming.
My airbag light is on. Will this fix it?
If the airbag light is caused by a BCM communication error (like DTC B1001), this module will resolve the root cause. However, after installation, you may need a technician with a professional scan tool to perform the ‘Setup SDM Primary Key’ function to clear the light.
Is this installation something I can do myself?
Yes, for many DIYers this is a very straightforward job. The module is typically easy to access under the dash and requires basic tools. The entire process often takes less than 15 minutes.
What is your warranty and core policy?
This module is backed by a one-year warranty against defects. There is absolutely no core charge, so you can keep your old part without any hassle or extra cost.
