Restore Full Electrical Function to Your GM Truck or SUV
Are you experiencing strange and frustrating electrical issues in your 2002 Chevrolet Silverado, GMC Sierra, or other compatible GM vehicle? Symptoms like flickering lights, unresponsive power windows and locks, or a security system that prevents your truck from starting are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of problems. This replacement BCM is the definitive, hassle-free solution to get your truck running reliably again.
This isn’t just a part in a box. It’s a complete solution. We program this module with the latest GM software updates specifically for your vehicle using the VIN you provide. This critical step ensures that the module communicates perfectly with your truck’s other systems right out of the box, saving you a costly and time-consuming trip to the dealership for programming.
From the Diagnostic Bay
We had a 2002 Sierra 1500 in the shop that was driving the owner mad. The horn would honk randomly, the dome light would flicker while driving, and sometimes the power locks wouldn’t respond at all. We checked all the wiring and grounds, which were solid. After connecting our diagnostic tool, we saw multiple communication error codes pointing straight to the BCM. We installed a VIN-programmed module just like this one, and it was like giving the truck a new brain. All the electrical gremlins vanished instantly. It’s a common failure point on these trucks, but thankfully, it’s a straightforward fix with the right part.
Is Your BCM Failing? Check for These Symptoms:
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lighting (flickering, staying on, or not turning on at all).
- ✔ The security or anti-theft system activating incorrectly, preventing the vehicle from starting.
- ✔ Inaccurate or completely dead gauges on the instrument panel.
- ✔ The radio or climate control system behaving unpredictably or not working.
- ✔ False warning lights, like the airbag light, appearing on the dashboard.

Installation and Post-Install Information
Installation is generally straightforward, with the BCM located under the steering column or in the center dash. While our VIN programming makes this a near plug-and-play repair, some vehicles may require a simple relearn procedure to sync specific systems. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control operation.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and climate controls.
What is VIN programming and why do I need it?
VIN programming loads your vehicle’s specific software and options onto the BCM. It’s essential for the module to work correctly with your truck’s unique features. We handle this for you before shipping.
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 cannot ship your order until we receive it.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is typically simple. The BCM is usually held in by a few bolts or clips under the dashboard. However, be aware that post-installation procedures may require a professional scan tool.
Will this fix my ‘Service 4WD’ message?
While a faulty BCM can cause a variety of issues, a ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM) or the 4WD selector switch. Please diagnose your vehicle properly before ordering.
Is there a core charge?
No. We do not require you to send your old BCM back. There is no core charge associated with this purchase.
