Are you battling frustrating electrical gremlins in your 2001 GM truck? Intermittent power windows, flickering lights, a malfunctioning security system, or strange instrument cluster behavior are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of confusing and unpredictable problems. This module is the direct-fit, reliable solution to restore full functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair process. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program the module with the latest GM software specific to your truck. This means no costly trip to the dealership for programming. It arrives at your door ready for installation, making the process as simple as possible.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system light stays on, or the vehicle won’t start due to a security fault.
- ✔ Inconsistent or incorrect readings on the instrument panel gauges.
- ✔ Radio or climate control systems behaving erratically.
- ✔ Communication errors with other vehicle modules when using a diagnostic scan tool.
Installation Notes for your 2001 Yukon Body Control Module
This BCM is located on the left-hand (driver’s) side of the dashboard. While installation is straightforward, please be aware of potential post-installation procedures that may be required for your specific vehicle. In many cases, the module is plug-and-play, but some systems may need to be re-synced.
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure the brake lights and traction control system function correctly.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that manages and controls many of the non-engine related electronic functions. This includes power windows, locks, interior and exterior lighting, security system, wipers, and more.
Does this BCM need to be programmed?
No, you do not need to take it to a dealer for programming. We handle that for you! We will program the module to your vehicle’s specific VIN before we ship it, making it a ready-to-install part.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, must be performed with a professional scan tool.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module without needing to send it back.
Will this fix my ‘Service 4WD’ message?
While the BCM communicates with many systems, a ‘Service 4WD’ message is typically caused by the Transfer Case Control Module (TCCM) or a component in the 4×4 system itself, not the BCM.
