Tired of Electrical Gremlins in Your GM Truck or SUV?
If your 2010 GMC Yukon XL 1500 is acting possessed—with flickering lights, malfunctioning power windows, a security light that won’t turn off, or random warning messages—the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it starts to go, it can create a cascade of frustrating and seemingly unrelated problems. Instead of spending a fortune at the dealership on diagnostics and programming, get the permanent fix right here.
This is a direct-fit BCM, part number 20864767, that we program specifically to your vehicle’s VIN before it ever leaves our shop. This means no extra trips, no expensive scan tools, and no surprise fees. You get a part that’s ready for installation right out of the box, loaded with the latest GM software updates to ensure peak performance and reliability. Restore order to your vehicle’s electronics with a dependable 2010 Yukon XL 1500 BCM.
A Technician’s Notebook: The Intermittent Fault Fiasco
A customer’s 2010 Yukon XL came into my bay last month with a laundry list of complaints: the radio would sometimes not turn on, the driver’s side window worked intermittently, and the anti-theft light would stay on, occasionally preventing the truck from starting. They had already replaced the battery and checked fuses with no luck. These are classic symptoms of a BCM that’s failing internally. The module’s processors get weak, causing data corruption and unpredictable behavior. We swapped in a VIN-programmed BCM like this one, and every single issue was resolved instantly. It’s often the one part that fixes a dozen problems.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lamps staying on or not turning on.
- ✔ The security or anti-theft light is illuminated on the dash, possibly causing a no-start condition.
- ✔ The horn honks randomly or doesn’t work.
- ✔ False warnings on the driver information center (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ The radio or infotainment system is malfunctioning.
A Straightforward Guide to BCM Installation
Installing your new 2010 Yukon XL 1500 BCM is a manageable job for a confident DIYer. The module is typically located under the driver’s side dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Access the Module: Remove the lower dash panel beneath the steering column. It’s usually held in by a few clips or screws.
- Locate the BCM: The BCM is a black plastic box with several large multi-pin electrical connectors. On this model, it’s mounted to a bracket in this area.
- Disconnect and Remove: Carefully press the release tabs on each electrical connector and pull them straight out. Then, unbolt or unclip the old BCM from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- Final Steps: Reinstall the lower dash panel and reconnect the negative battery terminal.
CRITICAL: Post-Installation Procedures
After installing your new BCM, a few final steps are required to ensure all vehicle systems communicate correctly. Do not skip this part!
- Airbag System Reset: To clear the airbag warning light, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level diagnostic tool. This re-establishes the security handshake between the new BCM and the airbag system.
- Brake Pedal Position Sensor Relearn: Some vehicles will require a brake pedal position sensor recalibration. This ensures the StabiliTrak and ABS systems function correctly. This also requires a proper diagnostic tool.
- Consult a Professional: If you are not equipped with the necessary tools for these procedures, a qualified technician can complete them quickly.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. You just need to provide us with your vehicle’s 17-digit VIN during or after checkout. The module will arrive ready to be installed.
Is this a simple plug-and-play installation?
The physical installation is plug-and-play. However, as noted above, you will likely need a professional-grade scan tool to perform the ‘Setup SDM Primary Key’ and ‘Brake Pedal Position Sensor Relearn’ procedures to ensure all systems work correctly and to clear any related warning lights.
Will this fix my ‘Service StabiliTrak’ warning light?
A failing BCM is a very common cause for this warning message on GM vehicles. While other issues can trigger it (like a wheel speed sensor), if you’re also experiencing other electrical symptoms, there’s a strong chance this BCM will resolve the problem.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your specific vehicle, as it contains information about your truck’s options and security system. We will contact you after your purchase to get this information.
Where is the BCM located on my 2010 Yukon XL?
On the 2010 GMC Yukon XL 1500, the Body Control Module is located under the driver’s side of the dashboard, usually attached to a bracket near the steering column and firewall.
