Are you experiencing bizarre electrical problems in your GMC Yukon XL or other compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose symptoms.
This is a direct replacement Body Control Module, part number 20839063, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load the latest software updates from GM, ensuring optimal performance and compatibility. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
From the Diagnostic Bay
We had a 2010 GMC Yukon XL 1500 come into the shop with a classic case of electronic chaos. The customer reported the dome lights would stay on, the radio would randomly shut off, and the ‘Service StabiliTrak’ message would appear intermittently. After hours of checking wiring and grounds, we isolated the issue to an internal fault in the BCM. Instead of a costly dealer replacement, we installed a VIN-programmed module just like this one. The installation was straightforward, and once connected, all the strange electrical gremlins were gone. The customer was back on the road the same day, problem solved.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Security system faults or the vehicle failing to recognize the key fob.
- ✔ Warning lights on the dashboard for various systems (ABS, Airbag, Traction Control).
- ✔ The engine cranks but will not start due to a security system immobilizer issue.
- ✔ Horn, wipers, or radio behaving unpredictably.

Post-Installation Information
While this 2010 Yukon XL BCM is delivered ready for installation, some vehicles may require a simple component relearn procedure after the new module is installed. These are not programming steps but rather synchronization steps that can sometimes be necessary.
- Airbag System Sync: If your 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 the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic functions not related to the engine, such as power windows, locks, lights, security system, wipers, and more. It acts as a central hub for these systems.
How do I know my BCM is the problem?
Diagnosing a BCM can be tricky as its symptoms can mimic other issues. However, if you’re experiencing multiple, unrelated electrical problems simultaneously (like power locks and interior lights failing together), it’s a strong indicator of a faulty BCM. A professional diagnostic scan can confirm the fault.
What information do you need to program the BCM?
After you place your order, we will need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the exact software and settings for your vehicle’s specific configuration.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s side. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors to the new module. No programming is required on your end.
What if my airbag light comes on after installation?
This is not a sign of a defective part. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a high-level diagnostic tool, which can be done by most automotive repair shops.
