Is your 2002 GM truck or SUV suffering from strange electrical issues? You’re not alone.
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. From flickering lights and malfunctioning power windows to a vehicle that won’t start, a faulty BCM can make your reliable truck feel unpredictable. This replacement Body Control Module, compatible with part number DKAK and others, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We take the guesswork and hassle out of the repair. Unlike a generic module from a parts store or salvage yard, this BCM is professionally programmed with the latest GM software specifically for your vehicle using your VIN. This means no expensive trips to the dealership for programming. It arrives ready for installation, designed to get you back on the road quickly and confidently.

Installation and Post-Install Procedures
While this module is designed for a direct-fit installation, some vehicles may require additional steps after the BCM is installed to ensure all systems communicate correctly. These are known as ‘relearn’ or ‘synchronization’ procedures.
- 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-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic functions not related to the engine, such as power windows, locks, lights, wipers, security system, and instrument panel gauges.
Is this BCM truly plug-and-play?
Yes, it is pre-programmed to your VIN, which handles the most critical step. You can install it and the vehicle will start and run. However, as noted, some vehicles may require simple relearn procedures for systems like the airbags or brakes, which can be done with a capable scan tool.
How do I find my part number to confirm fitment?
Your original BCM’s part number is printed on a white label on the module itself. On most of these GM trucks and SUVs, it’s located under the steering column or in the center dash area. This module replaces part numbers 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What information do you need from me to program the module?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This ensures we program the BCM with the correct software and settings for your exact vehicle.
Will this fix my ‘Security’ light and no-start problem?
A faulty BCM is a very common cause of security system issues on these GM vehicles. Replacing it with a correctly programmed module often resolves these no-start conditions.
