Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or random warning lights on your dash, you’re likely facing 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 cascade of frustrating and unpredictable issues. Stop chasing symptoms and address the root cause with our pre-programmed BCM, designed to restore full functionality to your vehicle.
From the Diagnostic Bay
We had a 2013 Silverado 2500 come into the shop with a complaint of a constantly dead battery and interior lights that would flicker randomly, even with the truck turned off. The owner had already replaced the battery and alternator twice. After hooking up our diagnostic scanner, we saw multiple communication codes pointing to the BCM. The module wasn’t allowing the truck’s systems to go to sleep, causing a parasitic drain that killed the battery overnight. Installing a VIN-programmed BCM like this one solved the drain, fixed the flickering lights, and saved the customer from any more wasted money on batteries.
Common Symptoms of a Failing 2012-2014 Yukon BCM
A faulty 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:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service 4WD,” “Service StabiliTrak”).
- ✔ Radio or climate control systems behaving erratically.
- ✔ Unexplained battery drain that leaves you stranded.
- ✔ Communication issues when trying to use a diagnostic scan tool.
The Plug-and-Programmed Solution
Don’t just buy a part; buy a complete solution. Dealerships will sell you a blank module and then charge you hundreds of dollars for programming. We eliminate that hassle and expense. When you purchase from us, you provide your vehicle’s VIN, and we program the module with the latest official GM software specifically for your truck or SUV. This ensures that all the features and options your vehicle came with from the factory will work correctly right out of the box. This is the most efficient and cost-effective way to get your vehicle back on the road and working properly.
Installation and Required Procedures
This BCM is located under the steering column and is typically a straightforward component to replace. However, after installation, some additional steps may be required to ensure all vehicle systems are synchronized.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary. This ensures your brake lights and traction control system function as intended.
Please Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Is this BCM truly plug-and-play?
It is pre-programmed to your VIN, which handles the most complex part of the installation. However, as noted, you may need a professional scan tool to perform an airbag system sync or a brake pedal position relearn to clear certain warning lights and ensure full system integration.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information to program the module correctly.
What tools are needed for the post-installation procedures?
The ‘Setup SDM Primary Key in BCM’ and brake pedal relearn procedures require a high-level, bidirectional diagnostic scan tool, such as a GM Tech 2, MDI, or equivalent professional-grade scanner. Basic OBD-II code readers cannot perform these functions.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module.
Will this fix my check engine light?
A BCM typically controls body functions, not engine or transmission functions. If you have a check engine light, the issue is likely with a different module, such as the Engine Control Module (ECM) or Transmission Control Module (TCM). This BCM will solve issues related to body electronics.
