Is your 2002 GM truck or SUV suffering from bizarre electrical issues?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a no-start condition, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We had a 2002 GMC Yukon come in that would randomly refuse to start. The owner had already replaced the battery and starter to no avail. The security light was flashing intermittently on the dash, which was our first clue. After connecting our diagnostic tool, we found communication errors with the BCM. Instead of more guesswork, we installed a VIN-programmed BCM. The truck started perfectly every time, and all the strange electrical gremlins disappeared. It’s a classic case where the central computer, not the mechanical parts, was the root of the problem.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system light stays on, or the vehicle won’t start due to a false security alert.
- ✔ Inconsistent or non-working dashboard gauges.
- ✔ Key fob not responding correctly.
- ✔ Unexplained battery drain when the vehicle is off.
A True Plug-and-Play Solution for Your 2002 Suburban 1500 BCM
Don’t waste time and money at the dealership. This Body Control Module is a direct-fit replacement for your original unit. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that all factory settings and options are correctly configured for your truck or SUV. We flash it with the latest GM software updates, so you’re getting a module that performs as well as, or better than, the original. Simply provide your VIN after purchase, and we’ll ship a module that’s ready for installation.
Installation and Post-Install Notes
Installation is straightforward, but in some cases, additional steps may be required to sync the new module with other systems in your vehicle. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional bi-directional scan tool to complete and will sync the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
There is no core charge for this module. You can keep your old part.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions like power windows, power locks, interior and exterior lighting, the security system, and dashboard warning lights.
Is this module difficult to install?
The physical installation is typically simple, involving unplugging the old module and plugging in the new one. It’s usually located under the steering column or in the center dash. Since we program it to your VIN, no initial programming is needed on your end, making it a plug-and-play process.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. This allows us to program the module with the correct software and vehicle-specific options before we ship it.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many systems, a ‘Service 4WD’ light is more commonly caused by the Transfer Case Control Module (TCCM) or a faulty encoder motor or switch. It’s best to have the codes scanned to pinpoint the exact cause before ordering.
What if my original part number isn’t 19208537?
This module is a direct replacement for several part numbers, including 15063578, 15081796, 15095334, DKAK, and DPNU. As long as your vehicle is listed in the fitment guide, this module will work.
