Restore Full Functionality to Your GM Truck’s Electronics
Are you battling bizarre electrical issues in your 2001 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, or a persistent security light are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement BCM is the definitive solution to restore your vehicle’s proper operation.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We program the module with the latest GM software updates using your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures compatibility and a straightforward installation process, getting you back on the road faster.
Direct Replacement 2001 Silverado BCM
This module is a direct-fit replacement for a wide range of 2001 GM trucks and SUVs. Installation is as simple as locating your old BCM (typically found under the driver’s side of the dashboard), disconnecting the electrical harnesses, and plugging in your new, pre-programmed unit. Because we handle the programming, you can avoid a costly trip to the dealership for software flashing.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft system light stays on, preventing the vehicle from starting.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication errors with diagnostic scan tools.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require minor post-installation procedures. If your airbag warning light illuminates after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure proper brake light and traction control operation. These procedures are not always required but are important to be aware of.
This unit is a direct replacement for part numbers: 09375899, 9392990, 09370249, and 19180223.
Best of all, there is no core charge. You can keep your original module.
