Is Your GM Vehicle Plagued by Electrical Gremlins?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and even communication between other critical modules. When the BCM starts to fail, it can cause a cascade of confusing and unpredictable problems that can be difficult to diagnose. This replacement Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We recently had a 2010 GMC Yukon XL 1500 in the shop with a list of bizarre symptoms. The owner reported that the radio would randomly shut off, the driver’s side power window worked only intermittently, and the ‘Service StabiliTrak’ warning light would flash on the dash. They had already replaced the battery with no success. A full diagnostic scan revealed multiple communication loss codes with various systems, all pointing back to a faulty BCM. By installing a VIN-programmed BCM like this one, we were able to resolve all the electrical issues in a single repair, saving the customer from costly and unnecessary component replacements.
Common Symptoms of a Failing 2010 Yukon XL BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic instrument cluster behavior or false warning lights.
- ✔ Malfunctioning interior or exterior lights that flicker or won’t turn on/off.
- ✔ Vehicle security system faults, including anti-theft activation or no-start conditions.
- ✔ Key fob or remote start system not responding.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ ‘Service Airbag’ or ‘Service StabiliTrak’ messages appearing on the dash.
Plug & Play Solution with VIN Programming
Don’t waste time and money at the dealership with expensive programming fees. We take the hassle out of the repair. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program this module with the latest GM software specific to your vehicle’s configuration. This ensures a seamless installation process. While the module is designed for a direct fit, some vehicles may require simple post-installation relearn procedures.
Post-Installation Requirements
After installing your new BCM, certain systems may need to be re-synchronized. This is a normal part of the process. The most common procedures are:
- Airbag System Sync: If the airbag warning light is 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 your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic accessories, such as lights, windows, security, door locks, and wipers.
Do I need to get this BCM programmed?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready for installation.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
Is this part difficult to install?
For someone with moderate mechanical skill, the physical installation is straightforward. It typically involves removing a few dash panels to access the module, which is often located under the steering column or in the center dash area. The most important part is our pre-programming, which eliminates the need for specialized dealer tools.
What if the airbag light comes on after I install it?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
