Tired of Electrical Gremlins in Your GM Truck?
Is your 2015 GMC Sierra or Chevy Silverado suddenly acting possessed? Flickering lights, windows with a mind of their own, or random warning messages on the dash are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. Dealerships will often quote you a fortune for a new module plus expensive programming fees. We offer a smarter, more affordable solution.
This is a comprehensive programming service for a replacement 2015 Sierra BCM. You simply send us your original module, and we transfer all of its critical data—VIN, mileage, security info, and vehicle options—to this fully tested replacement unit. It arrives back at your door, ready for a true plug-and-play installation. No dealer visits, no extra programming, no hassle.
From the Diagnostic Bay
I remember a 2015 Sierra 1500 that came into my shop with a laundry list of bizarre issues. The owner was frustrated with the dome lights flickering, the radio cutting out, and the “Service 4WD” message popping up for no reason. A quick scan revealed multiple communication loss codes (U-codes), all pointing back to the BCM. After confirming the module had good power and ground, we knew it was failing internally. Instead of a new BCM and a day lost at the dealer for programming, we used a cloned unit. The physical swap took under 30 minutes, and every single electrical issue was gone. This is the exact, reliable fix we provide with our service.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, a faulty Body Control Module is the likely culprit:
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ Interior or exterior lights flicker, stay on constantly, or won’t turn on.
- ✔ The vehicle’s anti-theft or security system malfunctions, potentially causing a no-start condition.
- ✔ The radio, infotainment screen, or instrument cluster gauges behave erratically.
- ✔ You see false warning messages on the driver information center (DIC).
- ✔ Your scan tool shows communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other B-codes.
Our Simple Mail-In and Installation Process
We’ve designed our process to be as straightforward as possible for both DIYers and professional shops.
- Purchase & Ship: After placing your order, we will promptly contact you with clear, simple instructions for shipping your original BCM to our facility.
- Expert Programming: Once we receive your module, our experienced technicians will professionally transfer all critical data to this replacement unit, ensuring a perfect match.
- Receive & Install: We ship the programmed BCM back to you, typically within one business day. It’s ready for installation right out of the box. And with no core charge, you can keep your old part.
- Safety First: Before you begin, always disconnect the negative terminal from your vehicle’s battery.
- Locate & Replace: On most 2015 Sierra and Silverado models, the BCM is located under the driver-side dashboard, near the steering column. Carefully unplug the electrical connectors and remove the module. Install the replacement BCM and secure it.
- Reconnect & Test: Plug in the electrical connectors and reconnect the negative battery terminal. Start the truck and thoroughly test all body functions (lights, locks, windows, radio, etc.) to confirm a successful repair.
Important Post-Installation Notes
While our programming makes this a plug-and-play part, some vehicle systems may require a quick sync procedure after the BCM is replaced. Always consult a factory service manual for your specific vehicle.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the systems and turns off the light. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
