Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2001 GM truck or SUV? Issues like erratic power windows, flickering lights, malfunctioning door locks, or a security system that acts 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 fails, it can cause a wide range of confusing and intermittent problems. This replacement BCM is the definitive solution to restore your vehicle’s electronic functions to factory-perfect condition.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and dealership hassle out of the equation. Before we ship your module, our experts will program it with the latest GM software, precisely matched to your vehicle using the VIN you provide. This ensures a seamless installation process, getting you back on the road without the need for expensive dealership programming.
Diagnosing a Faulty 2001 GM Truck BCM
A failing BCM can manifest in numerous ways, often making you think multiple components have failed at once. If you’re experiencing several of the following symptoms, your BCM is the most likely culprit.
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ The radio or climate controls behaving erratically.
- ✔ Warning lights on the dashboard appearing for no reason.
- ✔ Inconsistent or non-functional remote keyless entry.
Simple Installation and Post-Install Notes
Your new BCM arrives programmed and ready for installation. Simply locate your old BCM (typically found under the driver’s side of the dashboard), disconnect the battery, swap the modules, and reconnect the battery. While our programming handles the majority of the setup, some vehicles may require additional syncing procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
This module is a direct fit for part numbers: 09375899, 9392990, 09370249, and 19180223.
Frequently Asked Questions
What is the process after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We use this to load the correct, vehicle-specific software onto the BCM before shipping it to you. This makes the installation process as simple as possible.
Where is the BCM located on my 2001 truck?
The Body Control Module is typically located on the driver’s side, up under the dashboard, often near the steering column or emergency brake pedal.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many systems, a ‘Service 4WD’ light is more commonly related to the Transfer Case Control Module (TCCM) or a sensor/actuator in the 4WD system itself. It’s best to have the codes scanned to confirm the source of the fault.
What if the 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’s computer (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
