Are you battling frustrating electrical gremlins in your 2001 GM truck or SUV? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement BCM, part number 09375899, is the definitive solution to restore your vehicle’s functionality and your peace of mind.
From the Diagnostic Bay
We once had a 2001 Silverado in the shop where the owner had spent hundreds replacing the driver’s side window motor and switch, but the window still wouldn’t work. He was convinced the wiring was bad. After a quick scan, we found fault codes pointing directly to the BCM. The module’s internal driver for that window had failed. We installed a VIN-programmed BCM, and the original window motor and switch worked perfectly. It’s a classic case of treating the cause, not just the symptom.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ The horn sounding unexpectedly or not at all.
- ✔ Warning lights on the dash with no apparent cause.
- ✔ Wipers behaving erratically or not parking in the correct position.
Why Choose Our Programmed 2001 Sierra 1500 BCM?
Getting your truck back on the road shouldn’t be a hassle. That’s why we offer a simple, effective solution. Unlike a generic module from a parts store or salvage yard, this BCM is professionally programmed specifically for your vehicle before it ships. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and we handle the rest. We load the latest GM-certified software, ensuring optimal performance and compatibility. This process eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Simple Installation Process
This BCM is located on the driver’s side, under the dashboard. While installation is a direct replacement, some vehicles may require additional steps after the new module is connected. These are known as ‘relearn’ procedures and can sometimes be necessary to sync the new BCM with other modules in your vehicle.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure your brake lights and traction control system function as intended.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you a trip to the dealership.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, and the security system.
Where is the BCM located on my 2001 GM truck?
The BCM is typically located under the driver’s side of the dashboard, to the left of the steering column.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is this part truly plug-and-play?
For many vehicles, yes. However, due to variations in vehicle systems, some models may require the post-installation relearn procedures mentioned above for the airbag or brake pedal position sensor.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
