Are you experiencing frustrating electrical issues with your 2001 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, or a security system that prevents your vehicle from starting are all common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement BCM is the reliable, straightforward solution to restore your vehicle’s proper function.
This module arrives at your door pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical programming step ensures compatibility with your vehicle’s existing systems and options, saving you a trip to the dealership and expensive programming fees. Simply provide us with your VIN after your purchase, and our technicians will flash the module with the latest GM software updates before shipping it directly to you.

Important Post-Installation Information
While this module is programmed for your VIN to ensure core functionality, some vehicle systems may require a ‘handshake’ with the new BCM after installation. These are simple procedures that can be performed with a capable bi-directional scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is necessary to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Please Note: There is no core charge for this part. You can keep your old module, saving you the time and hassle of a core return.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, the security system, wipers, and climate controls.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Is this part difficult to install?
The BCM is typically located under the driver’s side of the dashboard. Installation involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. It is a manageable job for a DIYer with basic tools.
Will this fix my ‘Security’ light and no-start problem?
Yes, a failing BCM is one of the most common causes of Passlock security system issues in these GM trucks. Replacing it with a correctly programmed module will often resolve these starting problems.
Do I need a mechanic to perform the post-installation procedures?
The Airbag Sync and Brake Pedal Relearn procedures require a professional-grade diagnostic scan tool. While the physical installation is DIY-friendly, you may need to visit a local repair shop to complete these final steps if the warning lights appear.
