Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Flickering lights, a dead HVAC blower, power windows with a mind of their own, or an annoying airbag light that won’t turn off are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and disruptive issues. This genuine OEM-quality Body Control Module, equivalent to part number 22860591, is the definitive solution for a wide range of 2007-2013 GM trucks and SUVs, including the Chevrolet Silverado, GMC Sierra, Tahoe, and Cadillac Escalade.
Diagnosing a Faulty 2013 Sierra Denali BCM
A failing BCM doesn’t always present itself in the same way. It can be a slow decline or a sudden failure. If you’re experiencing any of the following issues, your BCM is the most likely culprit. This module is the direct replacement you need to get your vehicle back to 100% functionality.
Common Symptoms of BCM Failure
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC controls that are unresponsive or a blower motor that won’t turn on.
- ✔ The security system light flashing, preventing the engine from starting.
- ✔ Headlights, taillights, or interior lights behaving erratically.
- ✔ An airbag warning light on the dash, often with a DTC B1001.
- ✔ False warnings on the driver information center (DIC).
- ✔ Communication issues with other vehicle modules, leading to various DTCs.
Plug-and-Play Solution with VIN Programming
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide your vehicle’s VIN during checkout, and we will program the module with the latest GM software specific to your truck. This ensures that it works correctly right out of the box. No special tools, no dealer appointments, and no hidden fees. Plus, with no core charge, you can keep your old part without hassle.
Post-Installation Notes
While installation is a simple plug-in process, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on. This is not a reprogramming but a sync procedure that can be performed with most professional-grade diagnostic tools. Similarly, a Brake Pedal Position Relearn might be needed. Always consult your vehicle’s service manual or a certified technician if you are unsure about these final steps.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like power windows, locks, lights, wipers, security system, and the HVAC system, ensuring they all work together seamlessly.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and configuration onto the BCM. Without it, the module won’t know how to communicate with your truck’s other systems, leading to features not working or the vehicle not starting at all. Our pre-programming makes it a true plug-and-play part.
Will I need to go to the dealership after installing this module?
No. Our VIN programming service eliminates the need for any additional dealership programming. In some cases, a simple relearn or sync procedure may be required for the airbag system, which can be done by most independent repair shops.
What if my airbag light is on after installation?
If the airbag light is illuminated, you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool. This syncs the new BCM with your vehicle’s existing airbag system (SDM) to clear the warning light.
Is this part compatible with other part numbers?
Yes, this BCM is a direct replacement for a wide range of part numbers, including 25844480, 25835966, 15943678, 20939137, 22860591, and many more. It is designed to fit a broad selection of 2007-2013 GM trucks and SUVs.
