Is your 2001 Chevy Tahoe or GMC truck experiencing bizarre electrical issues?
If you’re dealing with flickering lights, malfunctioning power windows or locks, or a security system that acts up randomly, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating problems that are often difficult to diagnose. Don’t waste time and money replacing individual switches and motors. Address the root cause with our pre-programmed BCM.
From the Diagnostic Bay
We had a 2001 Silverado in the shop that was driving the owner crazy. The dome lights would stay on, the radio presets would disappear, and the power door locks worked intermittently. The owner had already replaced the driver’s door lock actuator and the headlight switch with no luck. After connecting our scan tool, we saw multiple communication loss codes with various accessory modules. This pointed directly to the central hub – the BCM. Once we installed a VIN-programmed BCM, all the strange electrical gremlins vanished instantly. It’s a classic case of the BCM failing and creating a chain reaction of seemingly unrelated issues.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks not working correctly.
- ✔ Vehicle security system faults or alarm sounding for no reason.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights illuminating without a clear cause.
- ✔ Communication issues between different electronic modules.
- ✔ Key fob not responding or intermittent operation.

Important Post-Installation Information
While this module is pre-programmed for your vehicle, some models may require additional relearn procedures after installation to ensure full functionality. These are simple procedures for a qualified technician with a professional diagnostic tool.
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required 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 for guidance.
Frequently Asked Questions
What does this BCM do?
The Body Control Module, or BCM, acts as the main computer for your vehicle’s comfort and convenience features. It controls functions like power windows, power locks, interior and exterior lighting, the security system, and the horn.
Is this part truly plug-and-play?
This BCM is pre-programmed to your vehicle’s VIN, which handles the most complex part of the installation. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be done by a mechanic with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to program the module specifically for your truck before we ship it.
What if my airbag light turns on after I install it?
If the airbag light illuminates, it simply means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A technician can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. This product has no core charge, so you are not required to return your original module.
Will this fit my 2001 GMC Sierra?
Yes, this BCM is compatible with the 2001 GMC Sierra, as well as the Yukon, Silverado, Suburban, and Tahoe models listed in the fitment details. It replaces several original part numbers.
