Are you tired of chasing electrical gremlins in your truck? A flickering dash, unpredictable power windows, or a climate control system with a mind of its own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating issues. This VIN-programmed Body Control Module, compatible with part number 15901388, is the direct-fit, reliable solution for your 2007-2013 GM truck or SUV, designed to restore full functionality without a trip to the dealership.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2013 Silverado 3500 that rolled into my bay with the strangest collection of symptoms. The owner said the radio would randomly change stations, the airbag light was on, and the wipers wouldn’t park correctly. He’d already replaced the battery and checked all the fuses. A scan showed a B1001 code and a network communication error. After confirming the main grounds were solid, all evidence pointed to an internal BCM failure. These modules manage so many circuits that when they start to fail, the symptoms seem unrelated. Installing a VIN-programmed BCM fixed every single issue in under 10 minutes. It’s the definitive fix for these specific electrical nightmares.
Why Choose Our Pre-Programmed 2013 Silverado 3500 BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the complex part for you. By programming the module to your vehicle’s specific VIN before shipping, we eliminate the need for expensive scan tools or dealership appointments. It arrives at your door ready to be installed, ensuring all factory options your truck was built with work correctly from the moment you plug it in. This process restores communication between critical systems, resolving common Diagnostic Trouble Codes (DTCs) and getting your workhorse back to peak reliability.
Is Your Truck Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or security system acting up.
- ✔ HVAC controls are unresponsive or the blower motor works intermittently.
- ✔ An active airbag warning light, often with DTC B1001.
- ✔ Strange electrical behavior, potential stalling, or communication codes with other modules.
- ✔ Problems with the vehicle’s anti-theft system or remote keyless entry.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electronic components.
- ✔ Locate the BCM: On most GM trucks from this era, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unclip or unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, wipers, windows, locks, and HVAC to ensure everything is working as it should.
Post-Installation Note: In some cases, particularly if you had an airbag light, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ function to clear the light. A Brake Pedal Position relearn might also be required on certain models.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. It arrives ready for a plug-and-play installation, saving you time and money.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We have a ‘no core charge’ policy, so you can keep your old module without any hassle.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of this code. Replacing it will likely solve the root problem, but you may need to perform an ‘SDM Key Setup’ with a compatible scan tool to sync the new BCM with the airbag system and turn off the light.
How difficult is the installation?
For most DIYers with basic tools, the installation is straightforward and takes less than 30 minutes. The BCM is typically located under the driver-side dash and is held in by simple clips or bolts.
Is there a warranty on this part?
Yes, this Body Control Module comes with our standard one-year warranty, giving you peace of mind and confidence in your repair.
