Restore Full Control Over Your Yukon’s Electronics
If you’re dealing with a frustrating array of electrical problems in your 2010 GMC Yukon—from flickering lights and malfunctioning power windows to a persistent ‘Service Theft System’ warning—the Body Control Module (BCM) is the most likely culprit. As the central command center for your truck’s comfort and security features, a failing BCM can make your reliable Yukon feel unpredictable. This isn’t just an annoyance; it can affect vehicle safety and security. We offer a dependable solution: a replacement BCM, part number 15276271, that arrives at your door fully programmed to your vehicle’s specific VIN.
From the Diagnostic Bay: The Case of the Haunted Yukon
I remember a customer bringing in his 2010 Yukon, completely fed up. He said, “It’s like my truck is possessed.” The dome lights would stay on, the radio would shut off randomly, and the power locks had a mind of their own. He’d already replaced the battery and checked fuses. After connecting my scan tool, I saw a slew of communication error codes (U-codes) pointing to a network issue. In my 20+ years of experience, these ghost-in-the-machine symptoms almost always lead back to one component: a failing BCM. The internal circuits and relays wear out over time, causing intermittent and confusing failures. Replacing it with a properly programmed unit solved every single one of his issues in one go.
Is Your Yukon Exhibiting These Strange Electrical Issues?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or the ‘Service Theft System’ message appearing on the dash.
- ✔ The radio or infotainment system shutting down unexpectedly.
- ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other U-codes stored in the system.
- ✔ Inconsistent instrument panel gauge behavior.
Your Straightforward BCM Installation Guide
Replacing the 2010 Yukon BCM is a manageable job for a confident DIYer. Our pre-programming service eliminates the most difficult step—the need for dealership tools. Follow these general steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes before beginning work.
- Locate the BCM: On the 2010 Yukon, the BCM is typically found under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the new BCM in the same location and securely reconnect all electrical harnesses. You’ll hear a click as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Steps: Start the vehicle and check for proper function of all body electronics. As noted below, some vehicles may require additional relearn procedures.
Important Post-Installation Information
While our goal is a plug-and-play experience, certain vehicle systems may require recalibration after a new 2010 Yukon BCM is installed. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure correct brake light operation and to prevent issues with the traction control system.
We provide this module with NO CORE CHARGE. You can keep your old part.

Frequently Asked Questions
What does a BCM do on a 2010 GMC Yukon?
The Body Control Module, or BCM, acts as the brain for your Yukon’s non-engine related electronics. It manages functions like your power windows and locks, interior and exterior lighting, security system, and instrument panel warnings.
Is this BCM really plug-and-play?
Yes, for most functions. We program the module to your vehicle’s VIN before shipping, which handles the most critical step. This allows you to install it without needing a trip to the dealer for initial programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN, as the programming is specific to your exact vehicle.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my ‘Service Theft System’ message?
In the vast majority of cases, yes. The anti-theft system is a core function managed by the BCM. A failing BCM is the most common cause of this warning message, and a new, properly programmed module will resolve it.
Do I have to return my old BCM?
No. We do not require you to send back your original module. There is no core charge associated with this purchase.
