Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that randomly activates? These frustrating and unpredictable electrical issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to the instrument cluster and anti-theft system. When it starts to fail, it can create a cascade of bizarre problems that are difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ Instrument cluster gauges behaving strangely or warning lights appearing for no reason.
- ✔ The anti-theft or security system preventing the vehicle from starting.
- ✔ Non-responsive keyless entry remote fobs.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ Horn honking unexpectedly or not working at all.
Your Direct-Fit Solution: The 2000 Suburban Body Control Module
Don’t let a faulty module keep your truck off the road. This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic functions to factory specifications. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door flashed with the latest GM software updates, tailored specifically for your truck’s options and configuration. This critical programming step ensures seamless integration and proper communication with your vehicle’s other electronic systems.
Simple Process, Lasting Results
Our process is designed to be straightforward for both DIY mechanics and professional technicians:
- Place Your Order: Purchase the module for your vehicle.
- Provide Your VIN: After checkout, simply send us your 17-digit VIN. This is crucial for the programming service.
- We Program & Ship: Our technicians will flash the module with the correct software and ship it directly to you.
- Install the Module: The BCM is typically located on the left-hand (driver’s) side of the dashboard. Once installed, some vehicles may require additional procedures.
Post-Installation Procedures
While our VIN programming handles the majority of the setup, some GM vehicles of this era may require a ‘relearn’ or ‘sync’ procedure after installation for certain systems. These may include:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a recalibration of the brake pedal position sensor may be necessary to ensure correct brake light and traction control operation.
Please consult a factory service manual or a qualified technician for specific guidance, as procedures can vary by exact model and options.
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 body functions not related to the engine. This includes power windows, locks, lights, wipers, the security system, and more.
Do I need to provide my VIN?
Yes, providing your vehicle’s 17-digit VIN is mandatory. We use it to program the module with the correct software and settings for your specific vehicle, which is essential for proper function and compatibility.
Is this part difficult to install?
The physical installation is typically straightforward for someone with moderate mechanical skill, as the BCM is usually accessible under the driver’s side dashboard. However, be aware that post-installation electronic procedures, like an airbag system sync, may require a professional-grade diagnostic tool.
What if my original part number isn’t 9371990?
This module is a direct replacement for several service numbers, including 19208539, 9371990, and 9385236. As long as your vehicle is on the compatibility list and your original module has one of these numbers, this part will work.
Is there a core charge?
No, there is no core charge for this module. You can keep your original part without needing to send it back to us.
