Restore Full Electrical Function to Your GM Truck or SUV
Is your GMC Yukon XL 2500, Chevrolet Silverado, or Cadillac Escalade plagued by frustrating electrical issues? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of unpredictable problems. This genuine GM BCM, part number 22860591, is the definitive solution to restore your vehicle’s functionality and reliability.
Symptoms of a Failing Body Control Module
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC system failures, such as the blower motor not working or temperature controls being inoperative.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions or random alarm activation.
- ✔ Intermittent stalling, misfires, or other strange electrical behavior due to grounding problems within the module.
- ✔ A variety of communication DTCs stored in the vehicle’s computer system.
From the Diagnostic Bay
We had a 2009 Silverado 2500 come into the shop with a classic case of BCM failure. The customer complained that his air conditioning would only work on high, his driver-side window wouldn’t roll down, and his key fob worked intermittently. After confirming power and grounds were good, we scanned the system and found multiple communication loss codes with the BCM. Instead of a costly trip to the dealership for programming, we installed one of our pre-programmed modules. In under 10 minutes, all functions were restored. The customer was thrilled to have his truck back to normal without the dealership hassle and expense.
The Plug-and-Play Solution: Your 2007-2011 Yukon XL BCM
The biggest hurdle in replacing a BCM has always been the need for expensive, dealer-specific programming. We eliminate that step entirely. Each module is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it integrates seamlessly with your truck’s existing systems right out of the box. There’s no need for a trip to the dealership or special scan tools for setup. This is a true plug-and-play repair that saves you time and money.
Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the driver-side dash, near the steering column. The physical swap takes only a few minutes. While our VIN programming handles the primary setup, some vehicles may require a couple of simple relearn procedures:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is a quick sync that ensures the new BCM communicates correctly with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper brake light and traction control operation.
This module is a direct replacement for a wide range of part numbers, including 25844480, 25835966, 15943678, 20939137, and 22860591. Best of all, there is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
Do I need to take my vehicle to the dealership for programming?
No. This Body Control Module comes pre-programmed to your vehicle’s VIN. It is designed for a direct, plug-and-play installation, saving you the time and expense of a dealership visit.
What tools are required for installation?
Basic hand tools are all that’s needed for the physical installation, which typically takes less than 15 minutes. In some cases where an airbag light persists, a professional-grade scan tool will be required to perform the SDM key sync procedure.
Is this compatible with my 2008 Chevrolet Silverado 1500?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. It directly replaces part numbers 25844480, 22860591, and many others listed in the description.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We do not have a core charge on this BCM, so you can keep your original module without any extra fees or hassle.
What happens if my airbag light stays on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure, which can be completed by a qualified technician with an advanced scan tool.
