Programmed 2015 Sierra 3500 BCM Body Control Module 13506936

Is Your Truck Experiencing Strange Electrical Problems?

If your 2015 GMC Sierra 3500 is suddenly acting possessed – with flickering lights, malfunctioning power windows, erratic dashboard warnings, or even a no-start condition – the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, managing everything from the interior lights and door locks to the security system and power accessories. When it fails, it can create a cascade of frustrating and seemingly unrelated issues.

The Dealership-Free Solution for Your 2015 Sierra 3500 BCM

Replacing a BCM isn’t as simple as swapping the part. A new module from the dealership is a blank slate and requires expensive, specialized programming to learn your vehicle’s specific VIN, security keys, and optional features. This means a costly part, a tow to the dealer, and hours of labor charges. We eliminate that entire process. Our service provides you with a fully programmed replacement BCM that is a true plug-and-play solution.

Here’s how our simple and effective cloning service works:

1. You purchase this BCM service.
2. We will contact you with clear instructions for shipping your original BCM to our facility.
3. Our expert technicians will professionally transfer all the critical data from your original module to this replacement unit. This includes your VIN, key information, and all factory settings.
4. We ship the programmed replacement BCM back to you, typically within 24-48 hours of receiving your original.
5. You install the module, and your truck’s electronics are restored to full functionality. No dealer visit required.

Common Symptoms of a Failing BCM

• ✔ Intermittent or non-working power windows, door locks, or mirrors.
• ✔ Horn honking unexpectedly or not working at all.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ False warnings on the instrument cluster (e.g., “Service Theft System”).
• ✔ Key fob not being recognized or working sporadically.
• ✔ Radio or infotainment system malfunctioning.
• ✔ Complete no-start condition where the engine won’t crank.

Installation and Post-Install Notes

Installation is straightforward. The BCM is typically located under the steering column on the driver’s side. Disconnect the negative battery terminal before you begin. Carefully unplug the electrical connectors from the old BCM, unbolt it, and install the replacement in its place. Reconnect the connectors and the battery terminal.

In some cases, minor follow-up procedures may be necessary:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system. This is only required if the light is on.
• Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and traction control function.

Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
