Restore Full Electrical Function to Your GM Truck or SUV
Are you experiencing a host of frustrating electrical problems in your GMC Yukon XL 2500, Chevrolet Silverado, or Cadillac Escalade? Issues like flickering lights, a dead HVAC system, malfunctioning power windows, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it malfunctions, it can make your truck feel unreliable and difficult to diagnose. This OEM-quality GM BCM, part number 15901388 (interchangeable with 25844480), is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation without the need for an expensive trip to the dealership.
Common Symptoms of a Failing 2007-2011 Yukon XL 2500 BCM
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s highly likely your Body Control Module is the culprit:
- ✔ Non-functional or erratic power windows, door locks, and interior/exterior lights.
- ✔ The HVAC blower motor or climate controls stop working completely or operate intermittently.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, causing no-start conditions, stalling, or misfires.
- ✔ Unresponsive remote keyless entry (RKE) fobs.
- ✔ A wide range of communication-related DTCs stored in the vehicle’s memory.
Plug-and-Play Installation and Post-Install Notes
This module is engineered for a straightforward installation. Located under the driver’s side dashboard, it can typically be swapped out in minutes. Because we program it to your VIN before shipping, it’s ready to go right out of the box. However, please be aware of a potential post-installation procedure. If the airbag light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” function using a professional-grade scan tool. This syncs the new BCM with the airbag system. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and traction control operation. This module requires no core return, so you can keep your old part without any hassle.
Frequently Asked Questions
What does the BCM do on a 2007-2011 GMC Yukon XL 2500?
The Body Control Module (BCM) is a computer that manages and controls the majority of your Yukon’s non-engine related electronic systems. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate controls.
Is this BCM truly plug-and-play?
Yes, it is. We pre-program the module to your vehicle’s specific VIN before it ships. This ensures it communicates correctly with your truck’s other systems, eliminating the need for dealership programming.
Where is the BCM located on my truck?
On most 2007-2013 GM trucks and SUVs like the Yukon, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
Will this fix my airbag light with a B1001 code?
A faulty BCM is a very common cause of an airbag light with code B1001. Replacing the BCM will fix the root cause, but you may need to perform an “SDM Primary Key Setup” with a professional scan tool to sync the new module and clear the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module without any extra fees or hassle.
