Programmed GM BCM 15872388 | VIN Flashed Body Control Module

Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution

Are you tired of chasing electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or a dashboard lit up with warning messages can be incredibly frustrating. These aren’t just annoyances; they’re often symptoms of a failing Body Control Module (BCM), the central computer responsible for managing your car’s body electronics. Driving with a faulty BCM can be unpredictable and compromise your vehicle’s features and comfort. Instead of facing a costly trip to the dealership for diagnostics and programming, get the definitive, ready-to-install solution right here.

This is a reliable replacement Body Control Module, a direct fit for a wide range of GM cars, trucks, and SUVs. The most significant benefit? We flash it with the latest GM software updates and program it specifically to your vehicle’s VIN before it ships. This means you get a component that’s truly ready for installation, eliminating the need for expensive scan tools or dealership appointments for programming. This is the most efficient way to get your vehicle back to 100% functionality.

Is Your Vehicle Showing These Telltale Signs?

A failing BCM can manifest in numerous ways. As the hub for your vehicle’s comfort and convenience features, its failure can disrupt many systems at once. Here are some of the most common indicators I’ve seen in my 20+ years of diagnostic work:

• ✔ Erratic power windows, door locks, or interior/exterior lights.
• ✔ Horn honking unexpectedly or not working at all.
• ✔ Dashboard warning lights (like the security or airbag light) staying on.
• ✔ Remote keyless entry (fob) failing to work consistently.
• ✔ Intermittent no-start conditions related to the vehicle’s anti-theft system.
• ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0151, or other B-series codes.

Your Straightforward BCM Installation Guide

Replacing your BCM is a manageable task for a confident DIYer. With our pre-programmed module, you skip the hardest part. Always consult your vehicle’s specific service manual, but here is a general guide to the process:

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. Locate the BCM: The location varies by model (see fitment list below). It’s typically found under the driver’s side or passenger’s side of the dashboard, or behind the center console.
3. Remove Trim Panels: Carefully remove any plastic trim or dash panels necessary to access the module. Keep track of all screws and clips.
4. Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it.
5. Install the New BCM: Mount your new, pre-programmed BCM in place and securely reconnect all the electrical harnesses. Ensure they click into place.
6. Reassemble and Reconnect: Reinstall any trim panels you removed and, finally, reconnect the negative battery terminal.
7. Perform Relearns (If Needed): Start the vehicle. If any warning lights appear (like the airbag light) or certain functions aren’t correct, proceed to the post-installation procedures noted below.

Important Post-Installation Information

While our Programmed GM BCM is designed for a simple swap, some vehicle systems may require recalibration to recognize the new module. This is normal. Key procedures include:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
• No Core Charge: You are not required to return your old module. This saves you the time, cost, and hassle of a core return.

Disclaimer: Vehicle systems are complex. For the safest and most effective repair, always refer to a factory service manual or consult with a qualified automotive technician.
