Are you battling frustrating electrical gremlins in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security light that won’t turn off are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We program the module to your vehicle’s specific VIN before it ships, loading it with the latest software updates directly from GM. This critical step ensures compatibility and proper operation, saving you from expensive programming fees and a mandatory trip to the dealership. Simply provide your VIN at checkout, and we handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light stays illuminated, preventing the vehicle from starting.
- ✔ The radio or climate control system behaves unpredictably.
- ✔ The horn honks randomly or doesn’t work.
- ✔ False warnings or messages on the instrument cluster.
Installation and Setup for Your 2002 Silverado Body Control Module
Because this module arrives programmed to your VIN, the physical installation is straightforward for many models. It’s designed to be a direct replacement for the original unit. However, depending on your vehicle’s specific configuration, a couple of simple post-installation procedures may be necessary.
- Airbag System Sync: If the airbag warning light appears after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
This unit is a direct replacement for part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU. Plus, there is no core charge, so you can keep your original module without any extra hassle or cost.
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, security system, and the radio.
Is this BCM ready to install out of the box?
Yes! This BCM is programmed to your vehicle’s VIN before we ship it. This makes the installation process much simpler and helps you avoid a trip to the dealership for programming. Some minor relearn procedures may be needed after installation.
Where do I provide my vehicle’s VIN?
You will be prompted to provide your VIN during the checkout process. Please ensure it is accurate, as we use it to program the module specifically for your vehicle.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any additional fees or need to return it.
