Restore Full Electrical Function to Your GM Truck or Van
Are you battling frustrating electrical gremlins in your GM vehicle? Issues like flickering lights, malfunctioning power windows, erratic gauges, or a security system that prevents your truck from starting are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module, part number 15116065, is the definitive solution to restore your vehicle’s proper operation and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would stay on, and occasionally the power locks wouldn’t respond. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of hours of complex wiring diagnostics, we installed a VIN-programmed BCM. The problems vanished instantly. It’s a classic case where replacing the central ‘brain’ is the most direct and effective repair.
Is Your GM Truck or Van Showing These Symptoms?
- ✔ Erratic power windows, mirrors, or door locks that work intermittently.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) that won’t turn on or off.
- ✔ Instrument cluster gauges behaving strangely or not working at all.
- ✔ Vehicle security system faults, causing a no-start condition.
- ✔ A ‘Service Electrical System’ message appearing on your driver information center.
- ✔ False warnings for doors being ajar or other systems.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with other modules.
The Plug-and-Play Solution: A Pre-Programmed GM BCM 15116065
Don’t waste time and money at the dealership. We simplify the repair process by pre-programming this BCM to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, loaded with the latest software updates from GM to ensure optimal performance and longevity. This eliminates the need for expensive programming tools or a trip to a mechanic for software flashing. Simply provide your VIN at checkout, and we handle the rest.
Installation and Post-Install Notes
Installation is straightforward for a DIYer with basic tools. The BCM is typically located under the steering column on trucks or in the center dash area on vans. After installation, please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installing the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure your brake lights and traction control system function correctly.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, the security system, and instrument cluster functions.
Is this BCM truly plug-and-play?
Yes, because we program it to your VIN before shipping, it is ready to be installed without needing further programming from a dealer. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
What if my airbag light is on after installation?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Will this fix my specific electrical problem?
This BCM is a common solution for a wide array of electrical issues. If your vehicle is exhibiting multiple symptoms from the list above, a faulty BCM is the most likely cause. Proper vehicle diagnostics are always recommended.
