Restore Your Truck’s Electrical System with a Plug-and-Play Solution
If you’re dealing with frustrating and unpredictable electrical problems in your 2001 GM truck, you know how quickly it can sideline your vehicle. One minute the power windows work, the next they don’t. The security light flashes for no reason, or worse, the truck won’t start. As a technician with over two decades of experience, I’ve seen these exact issues countless times, and they almost always point to a failing Body Control Module (BCM). The BCM is the central hub for your truck’s body electronics, and when it goes bad, it creates chaos. This isn’t just an annoyance; it’s a reliability issue.
We offer a straightforward, dependable fix: a replacement Body Control Module, part number 09370249, that arrives at your door fully programmed to your truck’s specific VIN. Simply provide us with your Vehicle Identification Number after purchase, and we’ll load the latest GM software onto the module. This means no expensive trips to the dealership for programming—you get a module that’s ready for installation right out of the box, restoring the performance and dependability you expect from your truck.
A Technician’s Notebook: The Case of the Haunted Sierra
A customer brought in his ’01 Sierra 2500 with a list of symptoms that sounded like a ghost was in the machine. The radio would turn on by itself, the dome light would flicker, and the power door locks had a mind of their own. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw several communication error codes (U-codes) pointing to the BCM. Instead of a complex and costly wiring chase, we started with the most likely culprit. Installing a VIN-programmed 2001 Sierra 2500 BCM solved every single issue in under an hour. It’s a classic example of how this single component can cause a cascade of confusing electrical failures.
Is Your Truck Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security or anti-theft light is illuminated, potentially causing a no-start condition.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Communication Diagnostic Trouble Codes (DTCs), particularly U-codes, stored in the system.
- ✔ The radio or other accessories turning on and off by themselves.
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a DIYer with basic tools. It’s typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most of these GM trucks, you’ll find the BCM mounted to the left of the steering column, often behind a lower dash panel.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place of the old one and securely reconnect all electrical harnesses.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Post-Install Checks: Start the vehicle and test all body functions—windows, locks, lights, and radio—to ensure proper operation. Please see the important notes below regarding potential follow-up procedures.
Important Post-Installation Information
While our VIN programming handles the heavy lifting, some vehicles may require a simple relearn procedure to sync all systems perfectly. This is normal. Please be aware of the following:
- 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 recalibration may be needed to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old BCM. There is no core charge or fee associated with this purchase.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the module. Just provide your VIN during checkout, and it will arrive ready to install. This saves you a trip to the dealer.
What tools are required for installation?
Basic hand tools are all that’s typically needed, such as a socket set and a panel removal tool to access the BCM under the dashboard. No special electronic tools are required for the physical installation.
What is a BCM and what does it do?
The Body Control Module (BCM) acts as the central computer for your vehicle’s electronic accessories. It controls functions like power windows, locks, interior/exterior lighting, the security system, and the instrument cluster.
My airbag light came on after I installed the new BCM. Is it defective?
No, this is a normal security feature on some vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool.
How do I find my part number to confirm a match?
Your original BCM will have a sticker with the part number on it. This module is a direct replacement for part numbers 09375899, 9392990, 09370249, and 19180223.
