Is Your GM Truck Experiencing Strange Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, or a security system that has a mind of its own, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, coordinating everything from the interior dome lights to the horn. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose.
This replacement Body Control Module, part number 09385236, is the definitive solution for restoring your vehicle’s electronic systems to factory-perfect operation. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that all of your truck’s original features and options are recognized and function correctly right out of the box, saving you a costly trip to the dealership for programming.
From the Diagnostic Bay
We had a 2000 Silverado 1500 come into the shop that was driving the owner crazy. The radio would randomly turn off, the power locks would cycle while driving, and the battery would be dead every few mornings. The owner had already replaced the battery and alternator. We checked for parasitic draws and found a significant one, but it was intermittent. After digging into the wiring diagrams and running network diagnostics, we saw communication dropouts from the BCM. It was failing internally and keeping other modules awake, draining the battery. Installing a VIN-programmed BCM like this one solved every single issue at once. It’s a classic case of one component causing multiple ‘ghost’ problems.
Diagnosing a Faulty 2000 Suburban Body Control Module
A failing BCM can manifest in many ways. If you’re noticing several of the symptoms below, it’s a strong indicator that your Body Control Module needs replacement. This module is a direct solution for these common failures.
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system or alarm malfunctioning or preventing the vehicle from starting.
- ✔ Instrument panel gauges behaving erratically or warning lights appearing for no reason.
- ✔ The radio or climate control system not functioning correctly.
- ✔ Communication errors with other modules when checked with a diagnostic scan tool (e.g., U-codes).
- ✔ Intermittent no-start conditions related to the Passlock security system.
Plug-and-Play Installation Process
Our goal is to make your repair as simple as possible. By providing us with your VIN during checkout, we flash the module with the latest GM software updates specific to your truck. This means the module arrives ready for installation without the need for additional dealer tools. While the physical installation is straightforward for a DIY mechanic, some vehicles may require simple post-installation relearn procedures.
Post-Installation Requirements
After installing your new 2000 Suburban Body Control Module, you may need to perform one of the following procedures. These are standard for this type of repair and can often be completed with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system. This is a safety measure and requires a professional scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and traction control system.
Please note: Specific procedures can vary by exact make and model. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you time and money.
Where is the BCM located on my 2000 GM truck?
On most models like the Suburban, Tahoe, Silverado, and Sierra, the BCM is located under the driver’s side of the dashboard, to the left of the steering column. On S10/Blazer models, it is often found in the center dash area.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit serial number. It contains information about the manufacturer, model, and specific options your vehicle was built with. We use it to load the correct software onto the BCM so that all of your vehicle’s features work perfectly.
Is this compatible with part number 9371990?
Yes, this module is a direct replacement for service numbers 09385236, 19208539, and 9371990, ensuring wide compatibility across many GM models.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
