Restore Full Control and End Electrical Frustrations in Your GM Vehicle
Are you dealing with baffling electrical issues in your 2010 GMC Yukon XL 1500? Flickering lights, malfunctioning power windows, a dead instrument cluster, or even a vehicle that won’t start can all point to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your reliable truck into a source of constant headaches. This isn’t just an annoyance; it can be a safety concern when critical systems like lighting and security are compromised.
This is a direct-fit replacement BCM, part number 20864768, which we pre-program specifically for your vehicle using our professional cloning service. By providing your Vehicle Identification Number (VIN) at checkout, you receive a module that is ready for installation, loaded with the latest GM software updates. This process eliminates the need for expensive dealership programming, saving you hundreds of dollars and significant downtime.
Case Study: A Tricky Diagnosis
I remember a 2010 Yukon XL that came into my shop with a laundry list of intermittent problems. The owner was frustrated because the power locks would work one day and not the next, the dome lights had a mind of their own, and the security light would stay on, sometimes preventing the engine from starting. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw several communication error codes (U-codes) pointing to the BCM. Instead of a hard failure, the module was failing intermittently due to internal circuit board corrosion—a common issue. We installed a VIN-programmed BCM just like this one, and every single one of his electrical gremlins vanished. It’s a perfect example of how one part can solve a dozen confusing symptoms.
Common Signs of a Failing BCM
If your vehicle is exhibiting these symptoms, a failing BCM is the likely cause. In my 20+ years of experience, these are the most frequent indicators I’ve seen in the service bay:
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, locks, or mirrors not working correctly.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ The horn honking unexpectedly or not at all.
- ✔ Instrument panel gauges or warning lights behaving erratically.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or B1001.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
Your Straightforward BCM Installation Path
Installing your pre-programmed BCM is a manageable job for a confident DIYer or any professional mechanic. For the 2010 Yukon XL 1500, the BCM is typically located under the steering column, to the left of the driver’s side dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On your Yukon, this usually involves removing the lower dash panel beneath the steering wheel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, windows, locks, wipers, etc. Note that some post-install procedures may be required as detailed below.
Important Post-Installation Information
Our cloning service handles the main programming, but due to the complex nature of modern vehicle systems, some additional steps might be necessary:
- Airbag System Sync: If the airbag warning light is illuminated 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 recalibration to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module, or BCM, is a computer that manages many of your vehicle’s non-engine-related functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and the instrument cluster.
Is this module truly ready to install?
Yes. We use a cloning service to program the replacement BCM with your vehicle’s specific VIN and the latest GM software. This means you can avoid a separate, costly trip to the dealer for programming.
Do I need to send my old BCM back?
No, we do not require your old part back. Our policy is simple: we ship you the programmed replacement, and your original module is always returned to you along with the new unit.
Why did my original BCM fail?
BCM failure can happen for several reasons, including voltage spikes, short circuits, or, most commonly, moisture intrusion leading to corrosion on the internal circuit board.
What tools are needed for the post-installation procedures?
Procedures like the Airbag System Sync or Brake Pedal Relearn require a professional-grade bidirectional scan tool (like a Tech 2, Snap-on, or Autel). Most local repair shops have this equipment if you are not equipped for it.
