Restore Full Electrical Function to Your GM Truck or SUV
Is your 2007-2011 GMC Yukon XL 2500, Chevrolet Silverado, or Cadillac Escalade suffering from bizarre electrical issues? Intermittent power windows, a malfunctioning climate control system, or a persistent airbag light can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of frustrating and difficult-to-diagnose problems. This genuine OEM-quality GM 25844480 BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
Diagnosing a Faulty Yukon XL 2500 BCM
A failing BCM doesn’t always trigger a check engine light, making it tricky to pinpoint. Instead, it manifests as a collection of seemingly unrelated electrical gremlins. If you’re experiencing several of the following symptoms, your BCM is the most likely cause.
Common Symptoms of BCM Failure
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) staying on or not turning on.
- ✔ HVAC and climate control functions are unresponsive, or the blower motor works intermittently.
- ✔ The vehicle’s security system malfunctions, causing false alarms or no-start conditions.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001 stored.
- ✔ Wipers behaving erratically, either not working or activating on their own.
- ✔ Communication errors between various electronic modules, leading to multiple diagnostic trouble codes (DTCs).
The Plug-and-Play Solution
The biggest hurdle in replacing a BCM has always been the need for expensive programming at a dealership. Our modules eliminate this step entirely. We flash the unit with the latest GM software and program it directly to your vehicle’s VIN before it ships. This ensures that all your vehicle’s original features and options are recognized and function correctly right out of the box. No dealer visit, no expensive scan tools, no hassle.
This module is a direct replacement for a wide range of original part numbers, including: 25835966, 15263363, 15263497, 15878753, 15284816, 15943678, 15926094, 15940214, 25790508, 25790509, 25823558, 25823559, 25835965, 25844479, 25971916, 25971917, 15901388, 20939137, 20939138, and 22860591.
Installation and Post-Install Notes
Physical installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. It involves disconnecting the negative battery terminal and carefully swapping a few electrical connectors. While the module is plug-and-play for most functions, please be aware of two potential post-installation procedures that may be required:
- 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: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Order this pre-programmed BCM today and confidently restore your vehicle’s electronic systems to perfect working order.
Frequently Asked Questions
What does the Body Control Module do on my 2008 GMC Sierra?
The BCM is a computer that controls most of your truck’s non-engine related electronics. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and HVAC climate controls.
Is this BCM ready to install right out of the box?
Yes. We pre-program the module to your vehicle’s specific VIN before shipping. This makes it a true plug-and-play part, eliminating the need for a costly trip to the dealership for programming.
Why is my airbag light on after installing the new BCM?
This is a common security feature. The new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional scan tool to turn off the light.
Where is the BCM located on a 2010 Chevy Tahoe?
On most GM trucks and SUVs from this era, including the Tahoe, the BCM is located under the driver’s side dashboard, typically to the left of the steering column.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module without any extra fees.
