This OEM-quality replacement, equivalent to part number 15263363, is the definitive solution to restore your vehicle’s functionality and peace of mind.
This module comes pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and programming fees. It’s a true plug-and-play solution designed for both professional mechanics and DIY enthusiasts. By installing our VIN-programmed 2007-2011 Yukon XL 1500 BCM, you’re not just replacing a part; you’re ensuring all integrated systems communicate correctly, from the security system to the climate controls.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in his ’09 Yukon XL last month, completely fed up. His dashboard lights would flicker randomly, the radio would cut out, and the power locks had a mind of their own. He’d already replaced the battery and checked the main grounds, convinced he had a phantom wiring short. After a quick scan, I saw a handful of communication codes pointing to the BCM. In my 20 years of experience, these symptoms are classic signs of an internal BCM failure. We swapped in a VIN-programmed module, and within 10 minutes, every single issue was resolved. It’s a reminder that sometimes the most complex-seeming electrical problems have a straightforward solution.
Is Your Yukon Exhibiting These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC system failures, including an unresponsive blower motor or erratic temperature control.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Malfunctioning security system, leading to no-start conditions or random alarm activation.
- ✔ Unpredictable interior or exterior lighting behavior.
- ✔ A host of communication-related DTCs stored in the vehicle’s memory.
A Straightforward Guide to BCM Installation
Replacing your 2007-2011 Yukon XL 1500 BCM is a job most owners can handle in their own driveway. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: The BCM is typically found under the driver’s side 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 need to be depressed. Once disconnected, remove the module from its mounting bracket.
- Install the New BCM: Mount the new, pre-programmed module in place and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Post-Installation Procedures: While the module is plug-and-play for most functions, you must perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the airbag light. Some vehicles may also require a brake pedal position sensor recalibration.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic systems. This includes power windows, locks, lights, wipers, the security system, and the HVAC climate control system.
Do I really need to have this module programmed?
Yes, programming is essential. The BCM needs your vehicle’s specific VIN to communicate correctly with other modules. We handle this for you before shipping, so it arrives ready to install without any need for a trip to the dealer.
Can I install this part myself?
Absolutely. The physical installation is a simple plug-and-play process that takes just a few minutes. However, be aware that post-installation steps, like resetting the airbag light, require a diagnostic scan tool with specific capabilities.
What happens if I don’t perform the ‘Setup SDM Primary Key’ procedure?
If you skip this step, the airbag warning light will remain illuminated on your dashboard, and the supplemental restraint system (SRS) may not function correctly in an accident. This is a critical safety step.
Will this fix the DTC B1001 code?
Yes, a faulty BCM is a very common cause of the B1001 code. Replacing the module and then performing the SDM key setup procedure is the correct repair to clear this code permanently.
Is there a core charge for this part?
No, there is no core charge. You can keep your old part without any hassle or need to return it.
