Restore Full Functionality to Your GM Vehicle
Are you dealing with frustrating and unpredictable electrical problems in your 2010 GMC Yukon? One moment the power windows work, the next they don’t. Maybe the radio is acting possessed, the security light is flashing for no reason, or worse, you’re facing an intermittent no-start condition that leaves you stranded. As a technician with over two decades of experience, I’ve seen these exact issues hundreds of times, and the culprit is almost always a failing Body Control Module (BCM).
The BCM is the central command center for your vehicle’s body electronics. It manages everything from your interior lights and power locks to the instrument cluster and security system. When it starts to fail, it can create a cascade of bizarre symptoms that are often misdiagnosed. Don’t waste time and money chasing electrical gremlins. This replacement 2010 Yukon Body Control Module is the direct, reliable solution to get your truck back to 100%.
A Technician’s Notebook: The Case of the Haunted SUV
Just last month, a 2010 Tahoe (which shares the same platform as the Yukon) was towed into my bay. The owner was at his wit’s end. The gauges would randomly sweep, the door locks would cycle on their own while driving, and the battery would be dead every few mornings. He’d already replaced the battery and alternator to no avail. After connecting my diagnostic scanner, I found a flurry of U-codes, specifically a U0140 (Lost Communication With Body Control Module). This pointed directly to a BCM failure. Water intrusion from a leaky windshield seal had corroded the BCM’s internal circuits. By installing a pre-programmed BCM like this one, we had him back on the road the same day with all electrical functions restored, saving him a costly trip to the dealership.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system light flashing, preventing the engine from starting (anti-theft fault).
- ✔ Instrument panel gauges behaving erratically or going dark.
- ✔ The radio or climate control system turning on and off randomly.
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or B1001.
- ✔ Unexplained battery drain that kills the battery overnight.
A Straightforward Guide to Your BCM Swap
Replacing the BCM in your Yukon is a manageable job for a DIYer with basic tools. The module is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most 2010 Yukons, it’s mounted to the left of the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the multiple electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed BCM into place. Firmly reconnect all electrical connectors, ensuring each one clicks securely into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Final Steps: Proceed with the mandatory post-installation procedures outlined below to ensure safety and full functionality.
CRITICAL: Post-Installation Procedures Required
After installing your new 2010 Yukon Body Control Module, you MUST perform these steps. Failure to do so can result in warning lights and compromised safety systems.
- Airbag System Reset: The airbag warning light will be on. You must use a compatible high-level diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the new BCM and the airbag module.
- Brake Pedal Position Sensor Relearn: Some vehicles require a brake pedal position sensor relearn procedure. This ensures the brake lights and stability control system function correctly. This is also performed with a diagnostic tool.
Note: If you are not comfortable with these procedures or do not have the required tools, we strongly recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN at checkout, and the module will arrive loaded with the latest GM software specific to your vehicle, ready for installation.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact factory software and configuration options for your specific 2010 Yukon, ensuring perfect compatibility with features like power seats, sunroof, and specific lighting options.
Will this fix my ‘Service StabiliTrak’ message?
While a failing BCM can contribute to various warning messages, the StabiliTrak system is complex. This module may resolve the issue if it’s caused by a BCM communication fault, but other components like wheel speed sensors or the steering angle sensor could also be the cause. A proper diagnosis is always recommended.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. The main challenge is ensuring the post-installation electronic procedures (airbag key setup, brake relearn) are performed correctly with a proper scan tool.
What happens if I don’t perform the post-installation procedures?
Your vehicle will likely run, but you will have a persistent airbag warning light on the dash, meaning the supplemental restraint system is inactive. You may also have incorrect brake light operation, which is a significant safety hazard.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been professionally programmed to function like new, providing a reliable and cost-effective solution.
