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 won’t cooperate? These frustrating and seemingly random 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 anti-theft system. When it starts to fail, it can create a cascade of bizarre problems that are difficult to diagnose.
We had a 2001 GMC Jimmy come into the shop with a classic case of BCM failure. The customer complained that his dome lights would stay on, the radio would randomly shut off, and his key fob stopped working. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing toward the BCM. Instead of a costly and time-consuming diagnostic chase, we recommended a VIN-programmed replacement. Once the new module was installed, all the strange electrical issues vanished instantly. It’s a perfect example of how replacing this one component can solve a dozen different problems.
The Direct Solution: A VIN-Programmed 2001 S10 BCM
Don’t let a faulty module keep your truck off the road. This replacement Body Control Module is the definitive solution for your 2001 S10, S15, Sonoma, Blazer, Jimmy, and a wide range of other GM trucks and SUVs from the 2000-2001 model years. The most critical part of the process is that we program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that the BCM communicates correctly with your vehicle’s other computers, retaining all original functions and features without a trip to the dealership for expensive programming.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Intermittent operation of the radio, horn, or windshield wipers.
- ✔ False warnings on the instrument cluster, such as a door ajar light that stays on.
- ✔ Key fob not responding or working intermittently.
- ✔ Communication error codes when scanned with a diagnostic tool.
Simple Installation and Post-Install Considerations
This module is designed for a straightforward installation. Once you provide us with your VIN during checkout, our technicians will handle all the necessary programming. When you receive the part, it’s ready to be installed. In most cases, it’s a plug-and-play process. However, on some vehicles, a couple of simple relearn procedures may be necessary after installation to ensure all systems are perfectly synchronized.
Important Note: While this 2001 S10 BCM is pre-programmed, certain integrated systems may require recalibration. If your airbag warning light appears after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position Relearn might be required to ensure proper brake light and traction control operation. Always consult a factory service manual for your specific model for detailed instructions.
This unit is a direct replacement for service numbers 19208539, 9371990, and 9385236. Plus, there is no core charge, so you can keep your original module without the hassle of sending it back.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior/exterior lights, the security system, wipers, and the horn.
Do I need to get this module programmed?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN at checkout, and the module will arrive ready for installation, configured specifically for your truck or SUV.
Where is the BCM located on my vehicle?
On the 2001 S10/S15/Sonoma, Blazer, and Jimmy, the BCM is typically located in the center of the dash. On larger trucks and SUVs like the Silverado, Sierra, and Tahoe from 2000, it’s usually found on the left-hand side of the dash.
What happens if the airbag light comes on after installation?
This indicates that the new BCM needs to be synchronized with the airbag system’s computer (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade diagnostic scan tool to resolve this.
Is this part compatible with my 2000 Silverado?
Yes, this BCM is compatible with many 2000 model year GM trucks, including the Silverado 1500/2500, Sierra 1500/2500, Tahoe, and Yukon, as long as the original part number is 9371990 or 9385236. Please verify the part number on your original module to ensure a perfect match.
