Is Your Truck Experiencing Bizarre Electrical Problems?
The Body Control Module, or BCM, is the central command center for your truck’s body electronics. It’s not just a fuse box; it’s a sophisticated computer that manages everything from your power windows and door locks to the interior lights, security system, and even communication between other vital modules. When the BCM in your 2015 GMC Sierra 1500 begins to fail, it can create a cascade of confusing and frustrating symptoms that seem unrelated, often leading to incorrect diagnoses and expensive, unnecessary repairs.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following issues, a faulty BCM could be the culprit. This module is the key to restoring proper function and getting your truck back to 100%.
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ The anti-theft or security system light is on, preventing the engine from starting.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) flicker, stay on, or won’t turn on.
- ✔ The horn honks randomly or doesn’t work when pressed.
- ✔ Wipers activate on their own or won’t shut off.
- ✔ Warning lights on the dashboard appear for no reason.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.

Important Post-Installation Information
While our programming makes this a plug-and-play installation, certain vehicle systems may require a quick sync-up procedure after the new BCM is installed. These are standard procedures for this type of repair.
- 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 compatible professional scan tool. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module (BCM) acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and more, ensuring all these components work together correctly.
Why do I have to send you my original BCM?
Your original BCM contains your truck’s unique Vehicle Identification Number (VIN), mileage, and settings for its specific options. By cloning this data to the replacement module, we make it a true plug-and-play part, saving you from a costly and time-consuming programming session at a dealership.
Is this installation difficult?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located under the steering column. The main challenge is ensuring the data is correct, which our cloning service handles for you. After swapping the module, you may need a scan tool for minor relearn procedures as noted.
How long does the programming service take?
We pride ourselves on a fast turnaround. Once we receive your original module, the programming process is typically completed and shipped back out within 1-2 business days.
Will this fix my ‘Service Theft Deterrent System’ message?
Yes, a failing BCM is one of the most common causes of a persistent security system error or a no-start condition with a flashing security light. A correctly programmed BCM will resolve these issues.
