Restore Your GM’s Electrical Systems with a Plug-and-Play BCM

Are you battling frustrating electrical gremlins in your 2010 Cadillac STS or another GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or random warning messages on the dash are classic signs of a failing Body Control Module (BCM). As the central command for your car’s comfort and convenience features, a faulty BCM can make driving a nightmare. In my 20+ years of diagnostics, I’ve seen how a single failing module can cause a cascade of seemingly unrelated problems, often leading to expensive and incorrect repairs.

This isn’t just a replacement part; it’s a complete, hassle-free solution. We take a genuine GM Body Control Module and program it specifically to your vehicle’s Vehicle Identification Number (VIN) before it ever leaves our facility. This means it arrives with the latest GM software updates, ready for installation. You get to skip the expensive trip to the dealership for programming, saving you time and hundreds of dollars. Restore your vehicle’s functionality and your peace of mind with a reliable, pre-programmed 2010 STS Body Control Module.

Is Your Vehicle Showing These Signs of BCM Failure?

A failing BCM can cause a wide range of symptoms. If you’re experiencing any of the following, your BCM is the likely culprit:

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, door locks, or mirrors not working correctly.
• ✔ The security system or keyless entry fails intermittently.
• ✔ Instrument cluster warnings (like the airbag or ABS light) appearing for no reason.
• ✔ Communication error codes, especially U-codes (e.g., U0140 – Lost Communication With Body Control Module).
• ✔ Climate control system behaving unpredictably.
• ✔ The vehicle may not start due to security system immobilization.

A Straightforward Guide to Your BCM Installation

Installing your pre-programmed BCM is a manageable job for a confident DIYer. While the exact location varies by model (see fitment list), it’s typically found under the driver’s or passenger’s side dashboard.

1. Safety First: 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: Remove any necessary trim panels to access the module. Its location is noted in our fitment list (e.g., ‘LH dash’, ‘center dash’).
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt the old BCM and remove it from the vehicle.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
5. Reconnect Battery: Re-attach the negative battery terminal.
6. Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. In most cases, the job is done. However, be aware of potential relearn procedures noted below.

Important Post-Install Note: Depending on your vehicle, you may need a professional scan tool for two potential procedures. An Airbag System Sync is needed if the airbag light stays on, and a Brake Pedal Position Relearn may be required for proper brake light and traction control function. Always consult a factory service manual for detailed instructions.
