Restore Full Functionality to Your Truck’s Electronics
Are you battling frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or random warning lights on your dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of confusing and unpredictable issues. This VIN-programmed Body Control Module, part number 15136876, is the direct-fit, reliable solution to get your vehicle back in perfect working order.
We had a 2005 Silverado 2500 come into the shop with a list of strange symptoms. The dome light would stay on, the driver’s side power lock was dead, and the radio would randomly shut off. The owner had already replaced the battery and checked fuses with no luck. After connecting our scan tool, we saw multiple communication loss codes pointing to the BCM. Instead of a dozen separate problems, it was one faulty module creating chaos. We installed a VIN-programmed GMC Sierra BCM like this one, and in under an hour, every single issue was resolved. It’s a perfect example of how this single component can restore a vehicle’s comfort and convenience features.
Your Programmed GMC Sierra BCM Solution
Forget expensive trips to the dealership for programming and diagnostics. We take the hassle out of the repair process. When you purchase this module, you simply provide us with your vehicle’s VIN. Our technicians will then flash the unit with the latest, most stable software updates directly from GM, ensuring it is perfectly matched to your truck’s specific options and configuration. This means when the part arrives, it’s ready for a straightforward installation. This module is a direct replacement for a range of part numbers, including 15167329, 15194169, 15747545, 15136224, and more.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior lights (dome, dash) flickering, staying on, or not turning on.
- ✔ Headlights or taillights malfunctioning.
- ✔ Horn sounding randomly or failing to work.
- ✔ Keyless entry remote (fob) not responding.
- ✔ Vehicle’s security or anti-theft system preventing it from starting.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Windshield wipers activating on their own or not working when commanded.
Installation and Post-Install Considerations
This BCM is typically located under the steering column on pickup models and in the center dash area on vans, making it accessible for replacement. Because we program the module before shipping, the process is significantly simplified. However, in some vehicles, additional synchronization procedures may be required after installation.
- Airbag System Sync: If the airbag warning light illuminates 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’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be needed to ensure correct operation of brake lights and stability control systems.
We make it easy with no core charge. You don’t have to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the brain for your vehicle’s non-engine related electronics. It controls functions like power windows, locks, interior and exterior lighting, the security system, wipers, and the horn, ensuring all these comfort and convenience features work together seamlessly.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical replacement is straightforward. It’s typically located under the driver’s side dashboard and involves disconnecting the battery and swapping a few electrical connectors. Since we pre-program it, you avoid the most complex step, which is the software flashing.
Why do you need my Vehicle Identification Number (VIN)?
Your vehicle’s VIN is essential because it allows us to program the BCM with the exact software and settings for your specific model, year, and factory-installed options (like power seats, keyless entry, etc.). This ensures a true plug-and-play experience and proper functionality.
Do I need to send my old module back?
No. This product has no core charge. You are not required to return your original BCM, which saves you time and return shipping costs.
What if my airbag light is on after I install the new GMC Sierra BCM?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
