Restore Command of Your Vehicle’s Electronics
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering dashboard lights, power windows with a mind of their own, a security system that won’t cooperate, or even a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central nervous system for your car’s body electronics, a faulty BCM can cause chaos. This isn’t just an annoyance; it can be a significant safety and reliability issue. This GM Body Control Module is the definitive, reliable solution to restore order and get your vehicle functioning correctly again.
A Technician’s Notebook
Just last week, a 2009 Chevy Impala was towed into my bay with a classic case of BCM failure. The customer complained of a battery that would die overnight and intermittent non-starting issues. A quick parasitic draw test showed a significant drain, but it was erratic. After isolating circuits, we traced the draw back to the BCM, which wasn’t letting other modules go to ‘sleep.’ Instead of a costly diagnostic and programming session at the dealership, we installed one of these pre-programmed BCMs. The draw vanished, and the car started reliably every time. This is a common scenario I’ve seen hundreds of times on vehicles from the Impala to the Tahoe, and a correctly programmed BCM is the only proper fix.
The Smart, Simple Solution: Pre-Programmed for You
Forget expensive dealership visits and the hassle of finding a shop with the right programming tools. We take the complexity out of the repair. When you purchase this BCM, you simply provide us with your vehicle’s VIN. Our certified technicians will then flash the module with the latest, most stable GM software specific to your car’s exact configuration. It arrives at your door ready for installation, saving you hundreds in programming fees and vehicle downtime. This is the most efficient way to replace your failing GM Body Control Module.
Is Your Vehicle Showing These Telltale Signs?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ A security system that engages randomly or prevents the car from starting (Security light on).
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or lights flickering.
- ✔ Communication error codes with other modules (U-codes).
- ✔ Horn, wipers, or other accessories not working as they should.
Your Straightforward Installation Guide
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: The location varies by model (see fitment list below). It’s typically found under the driver’s side dash, near the steering column, or in the center console area.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- CRITICAL Post-Installation Steps: Your vehicle will likely require two final procedures. An airbag warning light will be on until a ‘Setup SDM Primary Key in BCM’ procedure is done with a professional scan tool. Additionally, a Brake Pedal Position Sensor recalibration may be necessary to ensure proper brake light function and ABS performance.

Frequently Asked Questions
What do I need to do after I purchase this GM Body Control Module?
After you complete your order, please send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. We will flash the unit with the latest GM software matched to your vehicle’s specific options.
Is this a plug-and-play part?
Yes, this BCM is programmed before shipment, making the physical installation plug-and-play. However, as noted in the installation guide, you will need a professional scan tool to perform the ‘Setup SDM Primary Key’ and potentially a ‘Brake Pedal Position Relearn’ to clear warning lights and ensure full functionality.
Will this fix my parasitic battery drain?
In many cases, yes. A faulty BCM is a very common cause of parasitic battery drains on these GM vehicles because it fails to shut down properly, keeping other systems awake. If your diagnostics have pointed to the BCM, this part is the correct solution.
What if my original part number isn’t listed?
GM uses many different part numbers for the same component over the years. The list provided is extensive but may not be complete. The best way to ensure compatibility is to provide us with your VIN. We can verify the correct module for your vehicle.
Do I need any special tools for the installation?
For the physical replacement, you will only need basic hand tools like a socket set and screwdrivers to access the module. For the required post-installation procedures (like the airbag key setup), a bi-directional professional scan tool is necessary.
