Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your Chevrolet Suburban, Silverado, or GMC Sierra? Flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and disruptive problems. This genuine OEM-quality Body Control Module, interchangeable with part number 15940214 and 25844480, is the definitive solution to restore your vehicle’s performance and reliability.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights failing to turn on or off correctly.
- ✔ HVAC and climate control functions are unresponsive or the blower motor is erratic.
- ✔ The security system is malfunctioning, causing no-start conditions or false alarms.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Multiple diagnostic trouble codes (DTCs) related to body electronic systems.
The Plug-and-Play Solution for Your Suburban 2500 Body Control Module
Forget expensive dealership visits and programming fees. We pre-program this module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This ensures that it integrates seamlessly with your truck’s existing systems right out of the box. Loaded with the latest GM software updates, it communicates flawlessly with the Powertrain Control Module (PCM), anti-lock brake system, and other critical components, resolving common communication DTCs and restoring full functionality without any additional setup required.
Installation and Post-Install Procedures
Installation is a straightforward process for any DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. In most cases, it’s a simple swap that takes less than 15 minutes. However, please be aware of potential post-installation requirements:
- Airbag System Sync: If the airbag warning light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. 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 traction control operation.
This replacement Suburban 2500 Body Control Module is the most reliable and cost-effective way to solve your vehicle’s electrical gremlins and get back on the road with confidence. It is also a direct replacement for a wide range of GM vehicles including the Cadillac Escalade, Chevrolet Avalanche, Tahoe, and GMC Yukon models from 2007-2013.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, door locks, lighting, wipers, security system, and climate controls.
Do I need to have this module programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. This makes the installation plug-and-play, saving you the time and expense of a dealership visit.
Where is the BCM located on my 2008 Suburban 2500?
On most 2007-2013 GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
What if the airbag light stays on after I install the new BCM?
This indicates that the BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to clear the light.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any obligation to return it.
