Are you battling frustrating electrical issues in your 2001 GM truck or SUV? A failing Body Control Module (BCM) is often the culprit behind problems like erratic power windows, flickering lights, or a malfunctioning security system. This replacement BCM, part number 09375899, is the definitive solution to restore your vehicle’s electronic systems to perfect working order. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific VIN, ensuring a seamless installation process with the latest software updates from GM.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Instrument panel gauges behaving erratically or displaying incorrect information.
- ✔ The radio or climate control system functions improperly.
- ✔ Unexplained battery drain when the vehicle is turned off.
From the Diagnostic Bay
We had a 2001 Silverado 2500 come into the shop that the owner called his ‘ghost truck.’ The dome light would randomly turn on while driving, the horn would honk when he used the turn signal, and the radio would change stations on its own. He had already replaced the battery and checked all the fuses. After a quick scan, we pinpointed a communication fault with the BCM. Instead of a costly trip to the dealer for a new module and programming fees, he ordered one of our VIN-programmed units. He installed it himself in under an hour, and the ‘ghost’ was gone. It’s a perfect example of how a faulty BCM can cause a cascade of bizarre issues.
Why Choose Our Programmed 2001 GM Truck BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. When you order, we use the VIN you provide to flash the module with your vehicle’s exact configuration and the most current GM software available. This eliminates the need for expensive dealer programming or specialized scan tools for the initial setup. This module is a direct-fit replacement for several part numbers, including 09375899, 9392990, 09370249, and 19180223, making it a versatile fix for a wide range of vehicles.
This part will fit the following 2001 models:
- GMC Sierra 1500, 2500, 3500 Pickup
- Chevrolet Silverado 1500, 2500, 3500 Pickup
- GMC Yukon & Yukon XL 1500/2500
- Chevrolet Tahoe
- Chevrolet Suburban 1500/2500
Installation & Post-Install Procedures
Installation is straightforward, as the BCM is typically located on the driver’s side of the dashboard. While our programming handles the majority of the setup, some vehicles may require additional steps after the new module is connected:
- Airbag System Sync: If the airbag warning light is on 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: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that acts as a central hub for its electronic accessories. It controls functions that aren’t related to the engine, such as power windows, locks, lights, wipers, the security system, and the instrument cluster.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to work correctly.
Is this part difficult to install?
For someone with basic mechanical skills, replacing the BCM is generally a simple process. It’s usually located under the driver’s side dashboard and involves disconnecting the battery and swapping a few electrical connectors. However, some vehicles may require additional relearn procedures after installation.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this BCM fit my 2001 Tahoe if my original part number is 9392990?
Yes. This BCM is a direct replacement for part numbers 09375899, 9392990, 09370249, and 19180223. As long as your vehicle is a 2001 model listed in our fitment chart, this module will work perfectly once programmed to your VIN.
