Programmed GM Body Control Module 15819552 | 2008 – 2012

Tired of Your GM’s Electrical Gremlins?

Is your vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or a frustrating no-start condition can often be traced back to one component: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM goes bad, it can create a cascade of confusing and unpredictable problems. This isn’t just an annoyance; it’s a matter of reliability and safety.

This is a direct-fit replacement GM Body Control Module, pre-programmed specifically for your vehicle. We take the guesswork and expensive dealership trips out of the equation. Simply provide your VIN during checkout, and our technicians will flash the module with the latest GM software updates for your exact make and model. This ensures seamless integration and restores your vehicle’s functions to factory-perfect operation.

Is Your Vehicle Showing These Symptoms?

A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need:

• ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all)
• ✔ Power windows, locks, or mirrors operating intermittently or not at all
• ✔ The security system or keyless entry failing to work correctly
• ✔ Instrument cluster warning lights (like the airbag or security light) illuminating for no reason
• ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes (e.g., U0140, U0155)
• ✔ Unexplained battery drain when the vehicle is off
• ✔ Engine not cranking or starting despite a good battery and starter

A Straightforward Guide to Installation

Installing your pre-programmed GM Body Control Module is a manageable job for a confident DIYer. While the exact location varies by model (see fitment list), the process is generally similar.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning.
2. Locate the BCM: On most of these vehicles, the BCM is located under the driver’s side or center of the dashboard. Check your service manual for the precise location.
3. Disconnect and Remove: Carefully 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.
4. Install the New Module: Mount the new, pre-programmed BCM in the same position as the old one. Securely plug in all electrical connectors, ensuring they click into place.
5. Reconnect Power: Reconnect the negative battery terminal.
6. Perform Post-Install Checks: Start the vehicle and test all body functions—lights, wipers, windows, locks, etc. Note that some vehicles may require additional relearn procedures as outlined below.

Important Post-Installation Information

Because this GM Body Control Module is pre-programmed, you will avoid the need for dealer-level flashing. However, depending on your specific vehicle, a couple of simple relearn procedures may be necessary:

• ✔ 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 new BCM with the airbag system.
• ✔ Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
• ✔ No Core Charge: You are not required to return your old module. Keep it, discard it—the choice is yours!

Disclaimer: Always consult a factory service manual or a qualified professional if you are unsure about any step of the process.
