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 nervous system for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of confusing and seemingly unrelated problems. Don’t replace individual switches and motors until you’ve checked the source. This direct-fit BCM is your reliable, permanent solution.
From the Diagnostic Bay
We had a 2001 Tahoe come in where the owner had spent hundreds chasing electrical gremlins. His power locks worked intermittently, the dome light would stay on, and the radio would sometimes refuse to turn off after he left the truck. He had already replaced two window switches and the headlight switch to no avail. After a quick scan, we saw multiple communication codes pointing to the BCM. We installed a VIN-programmed BCM, and instantly, every single one of his electrical issues was resolved. It’s a reminder that a single faulty module can make an entire vehicle seem like it’s falling apart.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors not working or operating erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Instrument panel gauges behaving erratically or displaying warning lights.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Installation and Post-Install Information
Installation is straightforward, as the BCM is typically located under the driver’s side of the dashboard. After installing your new module, please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated 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. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
We have a no-hassle core policy. You are not required to return your original module.

Frequently Asked Questions
What does the BCM actually do?
The Body Control Module is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and interior accessories.
Is this part difficult to install?
The BCM is located on the driver’s side, under the dashboard. For someone with basic mechanical skills, swapping the module is a simple unbolt-and-unplug process. The key benefit here is that our pre-programming eliminates the need for dealer-level computer work after installation.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module without it.
Do I have to return my old BCM?
No. There is no core charge associated with this part. You can keep your original module.
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. A repair shop with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
