Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical problems in your 2001 GM truck or SUV? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it falters, it can cause a cascade of confusing and disruptive problems. This replacement BCM, part number 09392990, is the definitive solution to restore your vehicle’s proper function and reliability.
From the Diagnostic Bay
We had a 2001 Silverado 2500 towed in with a no-start condition. The owner had already replaced the battery and alternator, convinced it was a charging system issue. The dash lights would come on, but the engine wouldn’t crank. After a quick scan, we saw multiple communication errors pointing back to the BCM. The faulty module was preventing the security system from authorizing the ignition sequence. Instead of chasing phantom electrical draws, we installed a VIN-programmed BCM, and the truck fired right up. It’s a common misdiagnosis that costs owners time and money on unnecessary parts.
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 or anti-theft system preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights (like Airbag or ABS) staying on without a clear cause.
- ✔ Problems with the radio or climate control systems.

Don’t let a faulty BCM keep your truck off the road. We make the repair process straightforward. This module is professionally programmed with the latest GM software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This critical step ensures compatibility and proper communication with your vehicle’s other electronic systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, shipping you a part that’s ready for installation.
Installation and Post-Install Notes
This BCM is located on the left-hand (driver’s) side of the dash. While the physical swap is direct, some vehicles may require simple post-installation procedures. In some cases, an airbag warning light may appear; this is resolved with a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool. Additionally, a Brake Pedal Position relearn might be necessary to ensure proper brake light and traction control operation. Always consult a factory service manual for detailed instructions specific to your model.

This module is a direct replacement for the following part numbers: 09375899, 9392990, 09370249, 19180223. Please verify your original part number to ensure a perfect match.
Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes, for most functions. We program the module to your vehicle’s VIN before shipping, which handles the most complex part of the installation. In some cases, minor relearn procedures, like for the airbag or brake pedal position sensor, may be required after installation using a diagnostic tool.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot program and ship your module without it.
Will this fix my specific electrical problem?
This part is designed to correct issues directly caused by a faulty BCM, such as the symptoms listed above. While it solves the most common electrical problems, you should always ensure your vehicle has been properly diagnosed by a qualified technician.
What if my airbag light is on after I install this?
If the airbag light illuminates, it means the new BCM needs to be synced with the airbag system’s SDM. This is done with a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by most automotive repair shops with a professional-grade scan tool.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
