Restore Your Yukon’s Electrical Functions and Get Back on the Road
Are you dealing with baffling electrical issues in your 2010 GMC Yukon XL 1500? Erratic power windows, flickering lights, or a security system that has a mind of its own can be incredibly frustrating. These aren’t just annoyances; they’re often symptoms of a failing Body Control Module (BCM), the central command center for your truck’s comfort and convenience features. This replacement BCM is your direct-fit, reliable solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
A Technician’s Notebook: The Case of the Haunted SUV
I remember a 2010 Yukon XL that came into my bay with a list of complaints that sounded like it was possessed. The owner said the radio would switch off, the dome lights would flicker while driving, and sometimes the power locks wouldn’t respond to the key fob. He’d already replaced the battery. My initial checks on grounds and wiring came back clean. The scan tool, however, showed multiple ‘loss of communication’ codes with the BCM. After seeing hundreds of these GMT900-platform vehicles, I knew the signs. Internal solder joints and relays within the original BCM can fail over time, causing these exact kinds of intermittent, maddening problems. A VIN-programmed replacement BCM resolved every single issue, restoring the vehicle’s functions and the owner’s peace of mind.
Is Your Yukon Showing These Signs of BCM Failure?
A faulty BCM can cause a wide range of problems. If you’re experiencing any of the following, a failing Body Control Module is the likely culprit. This is especially true if you’re getting communication-related Diagnostic Trouble Codes (DTCs) like U0140.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights behaving erratically (flickering, staying on after the vehicle is off).
- ✔ “Service Theft Deterrent System” message appearing on the driver information center.
- ✔ A no-start condition where the engine doesn’t crank, even with a good battery and starter.
- ✔ Key fob or remote start functions are unresponsive.
- ✔ Wipers or horn activating unexpectedly.

A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- ✔ Access the Module: On the 2010 Yukon XL, the BCM is located under the driver’s side dashboard, typically to the left of the steering column. You will likely need to remove the lower dash cover for access.
- ✔ Unplug and Remove: Carefully disconnect the multiple electrical connectors from the old BCM. These connectors have locking tabs that must be depressed to release them. Once unplugged, unbolt the module from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Power Up: Reinstall any trim panels you removed and reconnect the negative battery terminal.
Important Post-Installation Steps
While this module is programmed for your vehicle, certain security and safety systems may require a ‘handshake’ with the new BCM. These procedures require a professional-grade bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, the “Setup SDM Primary Key in BCM” procedure is required to sync the systems. This is a critical safety step.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No! We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you the time, cost, and hassle of a dealership appointment.
What is a core charge?
A core charge is a refundable deposit paid for your old part. We have a no-hassle policy and require no core charge. You can keep or recycle your old module as you see fit.
What information do you need from me for programming?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This ensures we load the exact correct software for your truck’s specific options.
The airbag light is on after I installed the part. Is it defective?
No, this is an expected security handshake. A procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade scan tool to sync the new BCM with the airbag module and turn off the light.
Will this BCM fix all my electrical problems?
This module will correct any issues caused by an internal failure of the original BCM. However, it’s essential to perform proper diagnostics first to rule out other potential causes like bad wiring, faulty grounds, or failing sensors.
