Are you battling frustrating and unpredictable electrical problems in your GM truck, van, or SUV? When power windows, door locks, security systems, or interior lights start acting on their own, a failing Body Control Module (BCM) is often the culprit. Instead of facing a costly trip to the dealership for diagnostics and programming, get the definitive solution delivered to your door. This is a direct-replacement BCM, professionally programmed to your vehicle’s specific VIN, ensuring a straightforward installation and restoring the reliable performance you depend on.
Common Symptoms of a Failing BCM & Your Direct Solution
A faulty BCM can create a cascade of issues that make your vehicle unreliable. If you’re experiencing any of the following, this module is the solution you need:
- Erratic or non-functional power windows, door locks, and mirrors.
- The security or anti-theft light is flashing, preventing the engine from starting (Passlock/Passkey issues).
- Interior dome lights or dashboard lights staying on or not working at all.
- Inaccurate or dead gauges on the instrument cluster.
- Communication error codes (U-codes) stored in the diagnostic system.
Our service eliminates the guesswork. By providing us with your VIN, you receive a fully compatible Programmed 2002 GM Truck Body Control Module that is ready for installation right out of the box, flashed with the latest stable software from GM for optimal function.

An Expert’s Note: As a technician with over 20 years on the floor, I remember the days when replacing a BCM was a major job that always ended at the dealership’s programming station. You’d do the hard work of diagnosing and replacing the part, only to have the vehicle be a paperweight until it was programmed. This VIN-programming service changes the game for both DIYers and independent shops. It puts the power back in your hands, turning a complex electronic repair into a manageable, plug-in job that gets these reliable workhorses back on the road fast.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is the central computer for your vehicle’s body electronics. It controls non-engine-related functions like power windows, door locks, the security system, interior and exterior lighting, and the instrument cluster gauges. When it fails, these systems can become erratic or stop working completely.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest GM software specific to your vehicle’s build. We then flash this software onto the BCM, so it’s ready to communicate with all the other modules in your vehicle upon installation.
Is this a difficult part to install?
For most models, the BCM is located under the driver’s side of the dashboard and is accessible with basic hand tools. The physical replacement is a simple plug-and-play process. However, as noted, some vehicles may require a post-installation ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ with a professional scan tool to clear warning lights or ensure all systems function correctly.
Will this fix my specific security system problem?
A failing BCM is one of the most common causes of Passlock or Passkey security system issues in these GM vehicles, often resulting in a no-start condition. A new Programmed 2002 GM Truck Body Control Module is the correct repair for this issue when the BCM itself is the point of failure.
How can I be sure this fits my vehicle?
This module replaces a wide range of original part numbers, including 15063578, 15081796, 15095334, and DPNU. Please review the detailed fitment list on this page. The most important step is providing your VIN, which allows us to guarantee it is programmed correctly for your exact make, model, and year.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, saving you time and money on return shipping.
