Are you battling frustrating electrical issues in your 2001 GM truck or SUV? Flickering lights, malfunctioning power windows, a dead radio, or a security light that won’t turn off are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This pre-programmed BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
We take the guesswork and high dealership costs out of the equation. Simply provide your vehicle’s VIN during checkout, and our experts will program this module with the latest GM software specific to your truck. This ensures a seamless installation process and restores all factory operations. This is not a simple repair service; it’s a fully prepared replacement module, ready to be installed upon arrival.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system light stays on, preventing the vehicle from starting.
- ✔ The radio or climate control system behaves erratically or doesn’t power on.
- ✔ False warning lights appearing on the instrument cluster.
- ✔ Diagnostic trouble codes (DTCs) indicating a loss of communication with the BCM.
Why Choose Our 2001 Sierra Body Control Module?
This isn’t just a part; it’s a complete solution. Each 2001 Sierra Body Control Module is meticulously prepared and programmed to your specific vehicle using your VIN. This critical step ensures that the module communicates correctly with your truck’s other electronic systems, like the engine computer and instrument cluster, right out of the box. You get a reliable part with the newest software updates from GM, without the need for an expensive dealership visit for programming.
Installation and Post-Install Considerations
Installation is typically straightforward, as the BCM is located under the driver’s side of the dashboard. While the module is delivered ready for your vehicle, some models may require simple post-installation relearn procedures. These do not require the original programming tool but may need a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure correct brake light operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle responsible for managing and controlling electronic accessories that are not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM difficult to install?
For someone with basic mechanical skills, the physical installation is relatively simple. It’s usually located under the driver’s side dash and involves unplugging the old module and plugging in the new one. The key benefit of our product is that the complex programming is already done for you.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as we use it to program the BCM specifically for your truck.
Will I need a special scan tool after installation?
In some cases, yes. While the main programming is done, certain systems like the airbag (SRS) or brake position sensor may require a ‘relearn’ or ‘sync’ procedure with a professional-grade scan tool to clear warning lights and ensure full functionality.
How do I know this part will fit my truck?
Please check the part number on your original BCM. If it matches one of the numbers listed (09375899, 9392990, 09370249, 19180223), this module is the correct replacement for your vehicle.
