Is Your 2001 GM Truck Experiencing Bizarre Electrical Problems?
If your 2001 GMC Sierra, Chevy Silverado, Tahoe, or Yukon is suffering from strange and unpredictable electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to the interior lights and security system. When it starts to fail, it can create a host of frustrating problems that seem to have no logical cause.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security or anti-theft light is illuminated, potentially causing a no-start condition.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument panel.
- ✔ HVAC (heater and A/C) controls are unresponsive.

Installation & Required Procedures
Physically installing the BCM is straightforward. It is typically located under the driver’s side of the dashboard. While our programming handles the most critical step, some vehicles may require one or two simple relearn procedures after installation to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Where is the BCM located on my 2001 Sierra or Silverado?
The Body Control Module is typically found on the driver’s side, mounted under or behind the dashboard.
What if my airbag light comes on after I install this part?
