Are you experiencing frustrating electrical issues with your GM truck or SUV? Problems like flickering interior lights, malfunctioning power windows and locks, a security light that won’t turn off, or even a no-start condition can often be traced back to 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 the definitive solution to restore full functionality and reliability to your vehicle.
This is not just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense out of the repair process by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means you get a part loaded with the latest GM software updates, ensuring optimal performance and compatibility. Simply provide your VIN after purchase, and we’ll handle the complex programming, saving you a costly trip to the dealership. This makes the installation process as straightforward as possible.
Common Symptoms of a Failing GM 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 engine from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ The radio or climate control system turns on and off by itself.
- ✔ ‘Service 4WD’ or other warning messages appearing on the dash.
- ✔ The vehicle’s battery drains overnight due to a module not ‘sleeping’.
Solving Electrical Problems with a Programmed 2002 Yukon Body Control Module
Replacing your faulty BCM with this pre-programmed unit is the most effective way to solve these persistent electrical problems. Designed to be a direct replacement for part number 15063578 and its interchanges, this module restores the critical communication pathways between your vehicle’s switches and electronic components. Because we flash it with your VIN, it correctly recognizes all the specific options your vehicle was built with, from the trim level to the drivetrain configuration. This is a crucial step that generic, non-programmed modules cannot offer.
Installation and Post-Install Considerations
Installation is typically straightforward, as the BCM is often located under the steering column or behind the center dash panel. Once the new module is connected, most functions should be immediately restored. However, in some cases, additional steps may be required:
- 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 certain models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your old module without the hassle of returning it.
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 various electronic accessories not related to the engine. This includes power windows, locks, lights, wipers, the security system, and the instrument panel.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options from the GM database. This ensures the module works perfectly with your truck’s features right out of the box, eliminating the need for dealership programming.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is generally simple. The BCM is usually located under the driver’s side dashboard and is held in by a few bolts or clips. Since we pre-program it, the most difficult part of the job is already done for you.
Will this fix my ‘Security’ light issue?
Yes, a faulty BCM is a very common cause of an illuminated security light and a no-start condition in these GM vehicles. Replacing it with this VIN-programmed module is a primary solution for that specific problem.
What if my original part number is different?
This module is a direct replacement for several part numbers, including 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU. As long as your original module matches one of these numbers, this part will be a perfect fit.
