Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a storm of strange electrical problems in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? From flickering lights and malfunctioning power windows to a persistent airbag warning light, these issues often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create frustrating and difficult-to-diagnose symptoms. This genuine GM Body Control Module, part number 22860591, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM is the likely cause. Replacing it with our pre-programmed unit can resolve these issues:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Airbag warning light illuminated, often with DTC B1001.
- ✔ Security system malfunctions, causing no-start or stalling conditions.
- ✔ Wipers behaving erratically or not working at all.
- ✔ Communication errors with other vehicle modules.
Why Choose a VIN-Programmed 2007-2011 Escalade Body Control Module?
This isn’t just a replacement part; it’s a complete solution. We program the module with the latest GM software updates using your vehicle’s VIN before it ships. This critical step ensures that the BCM communicates flawlessly with your truck’s existing systems, including the engine computer, transmission module, and security system. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column, making physical installation straightforward. However, after installation, some vehicles may require additional electronic procedures:
- Airbag System Sync: If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and traction control function.
There is no core charge for this module. You can keep your old part without the hassle of returning it.
Frequently Asked Questions
