Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your 2001 GM truck or SUV? Problems like erratic power windows, door locks that have a mind of their own, a security light that won’t turn off, or strange instrument cluster behavior are often caused by a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and annoying problems. This replacement BCM, part number 9392990, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2001 Sierra 2500 in the shop that was a real head-scratcher. The owner complained of intermittent power lock failure and a battery that would drain overnight. We checked for draws and found the interior lights were staying on faintly, even when the truck was off. After ruling out door switches, we hooked up the scan tool and found multiple communication codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The electrical draw vanished, the locks worked perfectly, and the customer was back on the road the same day for a fraction of the dealership cost.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior lights staying on or not working at all.
- ✔ The security or anti-theft light is illuminated on the dash, possibly preventing the engine from starting.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
- ✔ Horn, wipers, or radio functioning incorrectly.
A Simple, Plug-and-Play Solution for Your 2001 Silverado BCM
Don’t let a faulty BCM keep your truck sidelined. This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program the module with the latest GM-certified software specific to your truck. This ensures perfect compatibility and function right out of the box, eliminating the need for expensive dealership programming.
Installation & Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the driver’s side of the dashboard. After installation, most vehicles will function perfectly. However, depending on your specific model and options, a couple of additional steps may be required:
- 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 your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Good news: There is no core charge for this part. You can keep your original module without needing to send it back.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related electronic functions, such as power windows, locks, interior and exterior lighting, security system, wipers, and the instrument cluster.
Is this part difficult to install?
The physical replacement is relatively simple, usually involving removing a few dash panels and connectors. The main benefit of our service is that the module arrives pre-programmed, which is the most difficult part of the job and typically requires dealer-level tools.
Where do I provide my VIN?
You can enter your 17-digit Vehicle Identification Number (VIN) during the checkout process. We cannot ship your order until we receive your VIN, as it is required for programming.
What if my 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 system (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, must be performed by a repair shop with a professional-grade diagnostic tool.
Do I need to return my old BCM?
No. There is no core charge or deposit associated with this part. You can keep your old module.
