Restore Your Vehicle’s Electrical System with a Plug-and-Programmed BCM
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant frustration. Are you dealing with flickering dashboard lights, power windows with a mind of their own, or a security system that prevents your car from starting? These aren’t just annoyances; they’re classic signs that your vehicle’s central command center—the BCM—is failing. This module is the solution, arriving at your door already programmed with the latest GM software specifically for your vehicle’s VIN.
A Technician’s Notebook: The Ghost in the 2009 Impala
A customer brought in a 2009 Chevy Impala with a laundry list of bizarre electrical issues. The radio would turn on and off, the interior lights would flicker, and sometimes the car just wouldn’t start, showing only a security light. They had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a slew of ‘U’ codes, indicating a loss of communication between modules. This pointed directly to the BCM. Instead of a costly dealer repair, we installed a VIN-programmed BCM like this one. The communication faults vanished, and all electrical functions returned to normal. It’s a common failure, and this is the most straightforward, reliable fix.
Common Signs of a Failing GM BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. Replacing it with our Programmed GM Body Control Module can resolve these issues and restore proper function.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from dashboard gauges or interior/exterior lighting.
- ✔ The security light stays on, often causing a no-start condition.
- ✔ Horn sounding randomly or not working at all.
- ✔ Problems with the climate control system.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0100, U0140, or other ‘U’ codes.
A Straightforward Guide to BCM Installation
Installing your new BCM is a manageable job for a DIYer or a quick task for a professional. Since we handle the programming, you can skip the expensive trip to the dealership for software flashing.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: The BCM is typically found under the driver’s side or passenger’s side of the dashboard, or in the center console area. Your service manual can confirm the exact location for your model.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Firmly reconnect all electrical connectors, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns (If Necessary): Start the vehicle. In some cases, you may need to perform additional procedures as outlined below.
Important Post-Installation Information
While this Programmed GM Body Control Module is designed for a simple installation, some vehicle systems may require recalibration to recognize the new part. Please be aware of the following potential steps:
- ✔ 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: Some models may require a brake pedal position sensor relearn to ensure correct brake light and traction control operation.
- ✔ No Core Charge: You are not required to send your old module back. There is no core charge or deposit associated with this purchase.
Disclaimer: Vehicle systems and required procedures can vary. We always recommend consulting a factory service manual or a certified technician for model-specific instructions.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready for installation.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information for programming.
What tools are needed for the post-installation relearn procedures?
The Airbag System Sync and Brake Pedal Position Relearn typically require a bi-directional professional diagnostic tool, such as those used by automotive repair shops. Basic code readers cannot perform these functions.
Is this BCM a guaranteed fix for my electrical problems?
This module corrects issues directly caused by a failed BCM. While the symptoms listed are very common for BCM failure, it’s essential to ensure your vehicle has been properly diagnosed. Other issues, like poor grounds or faulty wiring, can sometimes mimic BCM problems.
What if my original part number isn’t 10382479 but is on the list?
That’s perfectly fine. The extensive list of part numbers are all interchangeable. As long as your original part number is on our list, this module will work for your vehicle once programmed to your VIN.
Do I have to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
