Are you battling frustrating electrical problems in your 2002 GMC Yukon, Chevy Silverado, or another compatible GM vehicle? Issues like erratic power windows, flickering interior lights, a malfunctioning security system, or random warning messages on your dash are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement BCM is your direct, reliable solution to restore full functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program this module to your vehicle’s specific VIN before shipping. This critical step ensures that the BCM communicates correctly with your truck’s other systems, like the engine computer and instrument cluster, right out of the box. You get the benefit of the latest GM software updates without the hassle or expense of a trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system light is illuminated, or the vehicle won’t start due to a false security trigger.
- ✔ Inoperative radio or climate control functions.
- ✔ False warning messages on the instrument cluster.
- ✔ Communication errors when scanning with a diagnostic tool.
Simple Installation and Post-Install Notes
Replacing the BCM is typically a straightforward process. It’s located under the steering column or in the center dash, depending on your model. Simply disconnect the battery, remove the old module, plug in your new VIN-programmed unit, and reconnect the battery. While this is a plug-and-play solution for most functions, some vehicles may require a simple relearn procedure after installation.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
This module is a direct replacement for part numbers: 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU. Restore your vehicle’s electrical system to factory-perfect operation with this reliable, pre-programmed 2002 Yukon BCM.
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 various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these body-related functions.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the specific software and settings for your vehicle’s exact configuration. This ensures it works correctly with all your truck’s features and avoids a costly trip to the dealer for programming.
Is this BCM difficult to install?
For most DIY mechanics, the installation is straightforward. It involves disconnecting the battery, accessing the module (usually under the dash), and swapping the electrical connectors. However, as noted, some vehicles may require a post-install relearn procedure with a scan tool.
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 if my airbag light is on after I install the new BCM?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
