Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Is your 2010 GMC Yukon or other GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a frustrating no-start condition can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it goes bad, it can create a cascade of confusing and inconvenient problems. Don’t let a faulty module keep you off the road. This replacement BCM is the reliable, straightforward solution you need.
This isn’t just a generic part off the shelf. We take the guesswork and dealer expense out of the equation. Before this module ships, we will program it with the latest GM software updates specifically for your vehicle using the VIN you provide. This means it arrives at your door ready for installation, saving you the time, cost, and hassle of a trip to the dealership for expensive programming. It’s a direct-fit replacement designed to restore full functionality to your vehicle’s essential features.
From the Diagnostic Bay
We had a 2010 Tahoe come in that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and sometimes the power locks wouldn’t respond to the key fob. They had already replaced the battery and checked fuses, but the gremlins persisted. After hooking up our diagnostic tool, we saw communication errors pointing directly to the BCM. Instead of a costly dealer replacement and programming session, we installed one of our VIN-programmed modules. The installation was straightforward, and instantly, all the strange electrical issues were gone. The customer was thrilled to have their truck back to normal without a massive repair bill.
Solving Problems with Your 2010 Yukon BCM
A failing BCM doesn’t just cause minor annoyances; it can impact vehicle safety and security. This module is the core component that manages everything from your interior lights and power accessories to the anti-theft system. By replacing a faulty unit with our pre-programmed module, you are directly addressing the root cause of these issues and ensuring all related systems communicate and function as the factory intended.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The vehicle’s security or anti-theft system engaging randomly or preventing the engine from starting.
- ✔ Intermittent issues with the radio, climate controls, or other dashboard functions.
- ✔ Warning lights appearing on the dash without a clear cause.
- ✔ Complete loss of power to multiple accessory systems simultaneously.
- ✔ Battery drain while the vehicle is parked.
Installation and Post-Install Considerations
This module is a direct replacement for part number 20815898 and a wide range of other interchangeable part numbers listed in the fitment guide. After the physical installation, some vehicles may require additional syncing procedures for specific systems. For instance, if you see an airbag warning light, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control operation. These are standard procedures for this type of repair, and we always recommend consulting a factory service manual or a qualified technician for guidance.
This part is a direct fit for a wide range of GM vehicles, including models of the Acadia, Escalade, Avalanche, Tahoe, Suburban, Yukon, Impala, Express, Savana, and more. Please verify your part number against our extensive cross-reference list to ensure compatibility.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, locks, lights, wipers, the security system, and climate controls. It acts as a central hub for these electronic features.
Is this BCM ready to install out of the box?
Yes, for most functions. We program the BCM to your vehicle’s specific VIN before shipping, which handles the most critical part of the setup. This allows the vehicle to start and run. In some cases, minor relearn procedures, like for the airbag system or brake pedal sensor, may be needed after installation using a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for it to work in your vehicle.
What happens if my airbag light is on after installation?
If the airbag light is illuminated after installing the new BCM, it means the BCM and the airbag system’s SDM (Sensing and Diagnostic Module) need to be synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve the light.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep your original module without any additional fees or hassle.
