Programmed GM Body Control Module 10382479 | 2006-2013 Models

Restore Your Vehicle’s Electrical System with a Reliable BCM

If you’re dealing with a frustrating array of electrical problems in your GM vehicle—like flickering lights, malfunctioning power windows, a dead battery for no reason, or warning lights that won’t turn off—the culprit is often a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can wreak havoc, making your car or truck feel unreliable and unsafe. In my 20+ years of diagnostics, I’ve seen countless owners replace batteries and alternators, only to find the real issue was the BCM all along.

This isn’t just a replacement part; it’s a direct solution. We take the guesswork and dealership hassle out of the equation. Each GM Body Control Module is meticulously programmed to your specific vehicle using your VIN. This ensures that when it arrives, it’s ready to integrate seamlessly with your car’s existing systems. We load the latest GM software updates, which can often resolve issues that were present even in the original factory programming. Stop chasing electrical gremlins and get a part that’s designed to work right out of the box.

Common Signs of a Failing GM BCM

• ✔ Intermittent or non-working power windows, door locks, or mirrors.
• ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights (like ABS or Airbag) staying on.
• ✔ Headlights, taillights, or interior lights that flicker, stay on, or don’t work at all.
• ✔ Security system randomly activating or preventing the vehicle from starting (often showing a security light).
• ✔ Unexplained battery drain that leads to a no-start condition.
• ✔ Communication loss codes with other modules, such as U0140 (Lost Communication With Body Control Module).
• ✔ Malfunctioning HVAC controls or blower motor.

A Straightforward Guide to BCM Installation

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. ✔ Locate the BCM: The location varies by model. Common spots are under the driver’s side dash near the steering column, behind the center dash console, or on the passenger side kick panel. Your owner’s manual or a quick search for your specific model will confirm its location.
3. ✔ Remove Trim Panels: Carefully remove any plastic trim or dash panels necessary to access the module. Use a trim removal tool to avoid scratching or breaking clips.
4. ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
5. ✔ Install the New BCM: Mount your new, pre-programmed BCM into the bracket and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
6. ✔ Post-Installation Steps: Reconnect the battery terminal. Start the vehicle and check for proper function of all body electronics. In some cases, as detailed below, additional relearn procedures may be necessary for systems like the airbags or brakes.

Important Post-Installation Information

While this GM Body Control Module comes programmed for your VIN, some vehicle systems require a ‘handshake’ with the new module after installation. This may require a professional scan tool.

• Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is a security measure and is only required if the light appears.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
• No Core Charge: You are not required to return your old module. This saves you the hassle and cost of a core return.
