Restore Full Electronic Control to Your 2001 GM Truck or SUV
Are you battling bizarre electrical gremlins in your truck? Flickering lights, malfunctioning power windows, a security system with a mind of its own, or random warning messages on your dash are all classic signs of a failing Body Control Module (BCM). 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 and unpredictable problems. This replacement BCM is the definitive solution to restore your vehicle’s factory functions and get you back on the road with confidence.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost out of the repair process by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means you get a BCM loaded with the latest GM software updates, tailored specifically for your truck’s options and features, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2001 Sierra 2500 come into the shop with a complaint that was driving the owner crazy: the windshield wipers would turn on by themselves and wouldn’t shut off, even with the truck turned off! He had already replaced the wiper switch and the motor to no avail. After a quick diagnostic scan, we traced the fault to the BCM. It was sending a constant ‘on’ signal to the wiper circuit. We installed a VIN-programmed BCM, and the problem was solved instantly. It’s a perfect example of how a faulty BCM can create symptoms that seem completely unrelated.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Horn, radio, or windshield wipers activating unexpectedly.
- ✔ False warning lights or ‘Service Vehicle’ messages appearing on the instrument cluster.
- ✔ Inconsistent or failed communication with diagnostic scan tools.

Important Post-Installation Information
While this module is designed for a straightforward installation, some 2001 GM vehicles may require one or two simple recalibration procedures after the new BCM is installed. This is normal and ensures all related systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function properly.
Please note: No core charge is required. You can keep your original module.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories not related to the engine, such as power windows, locks, lights, wipers, the security system, and instrument panel gauges.
Is this a simple plug-and-play installation?
Because we pre-program the module to your VIN, it is nearly plug-and-play. You simply disconnect the old BCM and connect the new one. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems, which may require a diagnostic tool.
How do I provide my VIN for programming?
After you place your order, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
What happens if my airbag light is on after installation?
If the airbag light appears, it means the new BCM needs to be synchronized with your vehicle’s Sensing and Diagnostic Module (SDM). A qualified technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this BCM fix my specific electrical problem?
This part corrects issues directly caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of your problem before ordering.
