Are you chasing down bizarre electrical gremlins in your GM truck or SUV? One minute the power locks don’t work, the next the radio is acting up, or worse, the security light is preventing your vehicle from starting. As a technician with over two decades of experience, I’ve seen these exact frustrations countless times. The culprit is almost always a failing Body Control Module (BCM), the central computer for your vehicle’s comfort and convenience features. Stop throwing parts at the problem. This is the direct, reliable solution you’ve been looking for.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM BCM and flash it with the very latest, most stable software from General Motors, specifically programmed to your vehicle’s unique VIN. This means you skip the expensive trip to the dealership for programming. You get a module that is truly plug-and-play, designed to restore full functionality and eliminate those frustrating electrical issues for good. Simply provide your VIN at checkout, and we handle the rest, shipping you a part that’s ready for installation right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2013 Silverado 2500 that came into my shop with a complaint that would drive any owner crazy: intermittent no-start. The security light on the dash would flash, and the truck would be dead in the water. After 10 minutes, it might start right up. The owner had already replaced the battery and ignition switch. After connecting my scanner, I found a slew of U-codes (communication errors) pointing to the BCM. The module was intermittently failing, dropping communication with the key and the engine computer. We installed a pre-programmed GM Truck Body Control Module, and the problem was solved instantly. It’s a classic failure mode for these vehicles.
Is Your Truck or SUV Showing These Symptoms?
A failing BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is on, or the vehicle won’t start (anti-theft issue).
- ✔ Key fob not responding or working intermittently.
- ✔ Warning lights on the dashboard for ABS, Airbag, or Traction Control.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or B1001.
- ✔ Radio or infotainment system malfunctions.
A Straightforward Guide to Your BCM Installation
Replacing your GM Truck Body Control Module is a manageable job for a confident DIYer. It’s typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10-15 minutes to allow all modules to power down completely.
- Access the Module: You will likely need to remove the lower dash panel or knee bolster below the steering wheel to gain access to the BCM.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Reconnect all the electrical connectors, ensuring they click securely into place.
- Final Steps: Reinstall the dash panel you removed. Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, locks, windows, radio, etc.
Important Post-Installation Information
Because this GM Truck Body Control Module is pre-programmed, most vehicles will not require any further steps. However, in some cases, a simple relearn procedure may be needed to sync the new module with other systems in your vehicle.
- ✔ Airbag System Sync: If your 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 module.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation. This can also be done with a capable bidirectional scan tool.
- ✔ No Core Charge: We make it simple. There is no core charge on this part, so you don’t have to worry about the cost or hassle of sending your old, faulty module back to us.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a certified technician if you are unsure about any part of the installation or relearn process.

Frequently Asked Questions
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s VIN before we ship it. It arrives ready to install, saving you hundreds in dealership programming fees.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the BCM correctly for your specific vehicle and options.
Is this hard to install myself?
For someone with basic mechanical skills, it’s a very manageable job. The module is located under the dash and typically involves removing a panel and a few bolts. The key is that no special programming tools are needed.
What is a core charge? Do I have to send my old part back?
A core charge is a deposit you pay until you return your old part. We have NO CORE CHARGE on this module. You can keep your old part, which simplifies the process for you.
Will this fix my ‘Service StabiliTrak’ or ‘Service Traction Control’ message?
A failing BCM can sometimes cause these warnings due to communication issues with the brake system. While this module can be the cause, these warnings can also be triggered by other parts like wheel speed sensors. A proper diagnosis is always recommended.
