Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your 2001 GM truck? Flickering lights, malfunctioning power windows, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can make your reliable truck feel unpredictable. I’ve seen it countless times in the shop: owners chase down wiring issues or replace individual switches, only to find the root cause was the BCM all along. This isn’t just an annoyance; it can affect vehicle security and safety systems.
This is the direct, reliable fix you’ve been looking for. We offer a genuine replacement BCM, part number 9370249, that arrives at your door pre-programmed to your truck’s specific Vehicle Identification Number (VIN). This critical step ensures seamless communication with your truck’s other modules right out of the box. We handle the complex programming using the latest GM software updates, saving you a costly trip to the dealership and hours of diagnostic headaches. By installing our 2001 Silverado BCM, you’re not just replacing a part; you’re restoring the core functionality and reliability of your vehicle’s electronics.
A Technician’s Notebook
A customer’s 2001 Silverado 1500 came in last month with a bizarre list of complaints: the radio would turn on by itself, the dome light wouldn’t shut off, and the power locks worked intermittently. He had already replaced the battery and checked all the fuses. A quick scan with a professional tool showed multiple communication loss codes with the BCM. These ghost-like issues are textbook symptoms of internal BCM failure. We installed one of our pre-programmed modules, and within an hour, every single issue was resolved. It’s a common failure on these GMT800 platforms, but thankfully, it’s a straightforward fix with the right part.
Is Your Truck Showing These Symptoms?
A failing BCM can cause a wide range of issues. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that flicker, stay on, or won’t turn on.
- ✔ The security system or anti-theft light acting up, preventing the truck from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ The radio or other accessories turning on and off randomly.
- ✔ False warning lights appearing on the dashboard.
A Straightforward Guide to BCM Installation
Replacing the BCM is a manageable job for a DIYer with basic tools. The module is typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your truck’s battery before working on any electrical components.
- Locate the BCM: On most 2001 GM trucks, it’s found on the left side of the steering column, often attached to a metal bracket. You may need to remove a lower dash panel for access.
- Disconnect the Connectors: Carefully unplug the multiple wiring harnesses connected to the old BCM. They have locking tabs that need to be pressed to release them. Do not force them.
- Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the wiring harnesses.
- Reconnect the Battery: Once the new module is installed, reconnect the negative battery terminal.
- Perform Final Procedures: Follow the post-installation steps below to ensure all systems, like the airbags and brakes, are properly calibrated.
Important Final Steps After Installation
After you install your new 2001 Silverado BCM, a couple of final procedures are necessary to guarantee full functionality and safety. These steps require a professional-grade diagnostic scan tool.
- Airbag System Reset: To clear the airbag warning light, you must perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes the security handshake between the new BCM and the airbag’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Relearn: Some vehicles require a recalibration of the brake pedal position sensor. This ensures the brake lights and stability control systems receive accurate input from the pedal.
Note: If you are not comfortable performing these steps or do not have the required tools, we strongly recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to do any programming myself?
No. This BCM comes fully programmed to your vehicle’s VIN. Just provide us with your VIN during checkout, and we handle all the programming before shipping it to you.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your truck that controls functions not related to the engine, such as power windows, locks, lights, security system, and interior accessories.
Will this fix my truck’s no-start issue?
If your no-start problem is caused by the anti-theft or security system being triggered by a faulty BCM, then yes, this part will resolve it. The security light will typically be flashing or on solid if this is the case.
What tools are needed for the final airbag and brake procedures?
You will need a bi-directional diagnostic scan tool, such as a GM Tech 2, Snap-on, Autel, or a similar professional-grade device that can perform specific module setup procedures.
Is this a brand new part?
This is a high-quality, tested replacement part that has been expertly programmed with the latest GM software for your specific vehicle, ensuring reliable performance.
How do I find my current BCM part number?
The part number is printed on a sticker on the BCM itself. You will need to access the module, which is typically located under the driver’s side dashboard, to read the label.
