Restore Your Vehicle’s Electronics with a VIN-Programmed BCM
Are you chasing electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows or locks, or a security light that won’t turn off are more than just annoyances—they’re classic signs of a failing Body Control Module (BCM). The BCM is the nerve center for your car’s comfort and convenience features. When it starts to fail, it can make your vehicle feel unreliable. This replacement GM Body Control Module is the definitive solution, arriving at your door pre-programmed for your specific vehicle.
Forget about costly dealership visits for programming. Simply provide us with your vehicle’s VIN during checkout, and our expert technicians will flash this module with the latest GM software for your exact configuration. This means it’s ready for installation right out of the box, saving you time, money, and the headache of coordinating a tow or a trip to the service center. It’s a straightforward, effective fix designed for both professional mechanics and capable DIYers.
A Technician’s Notebook
I remember a 2008 Chevy Express 2500 work van that came into my shop. The owner was frustrated because the interior lights would stay on, draining the battery overnight, and the power locks worked intermittently. He had already replaced the battery and checked fuses. After connecting my scan tool, I found a series of U-codes (communication errors) pointing to the BCM. These modules, especially on high-use vehicles like vans, can fail from years of thermal cycles and vibrations. We installed one of our pre-programmed BCMs, and within an hour, all the phantom electrical issues were gone. It’s a common failure, but thankfully, it’s a very direct fix with the right part.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM could be the culprit. A failing module often won’t store a specific trouble code, but you may see communication errors like U0140.
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system light is illuminated, and the vehicle may not start.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Remote keyless entry fails to operate correctly.
- ✔ Wipers behaving erratically (e.g., won’t turn off).
A Straightforward Guide to BCM Installation
Replacing the BCM is a manageable job for most DIYers. While the location varies (see fitment list), the process is generally similar. Always consult a service manual for your specific model’s instructions and torque specs.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Depending on your model, it’s typically found under the driver’s side dash, behind the glove box, or in the center console area. You may need to remove a few trim panels to access it.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed GM Body Control Module in place and securely fasten it. Reconnect all the electrical connectors, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns: Start the vehicle and check all functions. As noted below, you may need to perform a Brake Pedal Position Relearn or an Airbag System Sync if you see any related warning lights.
Important Post-Installation Information
This module is designed for a simple installation, but some vehicle systems may require recalibration. Please be aware of the following potential procedures:
- 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 this procedure to ensure correct brake light and traction control operation. This can often be done with a high-end scan tool.
- No Core Charge: You are not required to return your old BCM. There is no core charge or fee associated with this purchase.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for guidance specific to your make and model.

Frequently Asked Questions
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. Just provide your VIN at checkout, and the module will arrive ready for installation.
Is this a new or used part?
This is a professionally inspected and verified component that has been tested to meet or exceed original equipment standards. It is flashed with the latest official GM software.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot program and ship your GM Body Control Module without it, which will cause delays in your order.
Will this fix my “Service StabiliTrak” message?
While a failing BCM can sometimes contribute to these warnings by disrupting communication, StabiliTrak issues are more commonly caused by wheel speed sensors, the steering angle sensor, or the brake pedal position sensor. If a brake relearn is needed after install, it could be related.
What tools do I need for the installation?
Basic hand tools like a socket set, ratchet, and trim removal tools are usually all that’s required. For potential post-installation relearn procedures, a professional-grade bidirectional scan tool is necessary.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep or responsibly recycle your original module.
