Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Chevrolet Suburban, Tahoe, or Silverado? Issues like intermittent power windows, a malfunctioning HVAC system, or random security alerts often point to a single culprit: a failing Body Control Module (BCM). This vital component acts as the central hub for your vehicle’s body electronics. This genuine quality GM BCM, interchangeable with part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
From the Diagnostic Bay
We once had a 2009 Sierra in the shop with a classic case of electrical chaos. The owner had spent weeks chasing what he thought was a bad ground—the radio would cut out, the dome light would flicker, and the door locks had a mind of their own. After checking all the main grounding points, we finally scanned the BCM and found a slew of communication errors. A new, programmed BCM fixed every single issue in under 10 minutes. Don’t waste time chasing wires; a faulty BCM is often the root cause.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) failing to work correctly.
- ✔ HVAC and climate control functions becoming unresponsive or blowing air incorrectly.
- ✔ The security system engaging randomly, preventing the vehicle from starting.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Unexplained battery drain while the vehicle is parked.
Solving Problems with a Programmed 2007-2011 Suburban BCM
The Body Control Module is the nerve center for dozens of vehicle functions. Over time, internal components can fail due to heat cycles, voltage spikes, or moisture intrusion, leading to the unpredictable issues you’re experiencing. Replacing your faulty unit with our pre-programmed 2007-2011 Suburban BCM is the most effective way to restore your vehicle’s factory operations. We handle the complex programming for you, loading the latest GM software and your vehicle’s VIN before it ships. This eliminates the need for expensive dealership tools or additional programming fees, making the repair straightforward and cost-effective.
Installation and Post-Install Procedures
Physically installing the BCM is simple. It’s typically located under the driver’s side dashboard, near the steering column, and can be swapped out in minutes. However, please be aware of potential post-installation steps:
- Airbag System Sync: If the airbag light appears after installation, a technician must perform the “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. 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 stability control function.
This module is a direct replacement for numerous part numbers, including 25844480, 25835966, 15943678, 20939137, and more, ensuring wide compatibility across the GM truck and SUV lineup from 2007-2013.

My airbag light is on after installing the new BCM. What should I do?
This is a normal security measure. You will need a scan tool with advanced functions to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules and turn off the light.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module without any extra fees.
Where is the BCM located on a 2008 Chevy Silverado or GMC Sierra?
On most compatible GM trucks and SUVs, including the Silverado, Sierra, and Suburban, the BCM is located under the driver-side dashboard, to the left of the steering column.
