Restore Full Control of Your Yukon’s Electronics
Are you dealing with baffling electrical issues in your GMC Yukon? One moment the power windows work, the next they don’t. The A/C blower motor has a mind of its own, and a persistent airbag light is on your dash. These aren’t just minor annoyances; they’re classic signs of a failing Body Control Module (BCM). This VIN-programmed BCM, compatible with part number 15943678, is the definitive, dealership-free solution to restore your vehicle’s functionality and your peace of mind.
As the central command for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating problems. Our replacement 2007-2011 Yukon BCM arrives pre-programmed to your vehicle’s specific VIN. This crucial step ensures that the module communicates flawlessly with your truck’s existing systems right out of the box. You get a reliable, plug-and-play repair without the expensive trip to a dealership for programming.
Case Study: A Tricky Diagnosis
A customer brought in a 2009 Sierra with a list of complaints: intermittent radio, flickering dome lights, and a security light that would occasionally prevent the truck from starting. They had already replaced the battery and checked the main grounds. In my 20+ years of experience, I’ve seen these exact symptoms hundreds of times. While poor grounds on the GMT900 platform are common, the combination of security, lighting, and accessory faults pointed directly to the BCM. The internal logic was failing, causing unpredictable commands. We installed a VIN-programmed BCM, and all issues were resolved in under 15 minutes. It’s a reminder that what looks like multiple separate problems is often one central failure.
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 highly likely your BCM is the culprit. This 2007-2011 Yukon BCM is designed to solve these exact problems.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system malfunctions, causing no-start conditions or false alarms.
- ✔ An airbag warning light is illuminated on the dashboard, often with DTC B1001.
- ✔ Headlights, taillights, or interior lights flicker or fail to turn on/off correctly.
- ✔ Windshield wipers behaving erratically.
A Straightforward Guide to Installation
One of the best features of our pre-programmed modules is the simple installation. You don’t need to be a master mechanic to get your truck back in order. The entire process typically takes less than 15 minutes.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most 2007-2011 Yukon and similar GM models, the BCM is located under the driver’s side dashboard, to the left of the steering column.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Do not force them.
- Swap the Module: Unclip or unbolt the old BCM and remove it. Mount the new module in its place.
- Reconnect Everything: Plug the electrical connectors firmly into your new BCM. Reconnect the negative battery terminal.
- Post-Install Check: Start the vehicle and test all functions (windows, locks, HVAC, lights). If the airbag light remains on, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool. A brake pedal position relearn may also be required for some models.

Frequently Asked Questions
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for a plug-and-play installation, saving you time and money.
What if my airbag light is on after installation?
This is a common security feature. If the airbag light persists (often with code B1001), a technician must use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
Is there a core charge for my old part?
No, there is no core charge. You can keep or dispose of your old module without the hassle of sending it back.
Will this fix my ‘Service 4WD’ message?
While the BCM communicates with many systems, a ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM), a sensor, or the encoder motor. It’s best to diagnose that issue separately.
