Restore Full Electrical Control to Your GM Truck or Van
Are you battling bizarre electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or random warning lights on your dash are all 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 starts to fail, it can cause a wide range of frustrating and unpredictable issues. This replacement BCM, part number 15747545, is the definitive solution to restore your vehicle’s proper function and reliability.
Why Choose Our Pre-Programmed 2003-2007 Savana BCM?
Getting back on the road shouldn’t be complicated. Unlike a standard replacement from a dealer, this BCM arrives at your door pre-programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming. Simply provide us with your VIN after purchase, and we handle the complex part, ensuring a smoother installation process for you or your mechanic.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors not working correctly.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False warnings on the instrument cluster (e.g., ‘Service 4WD’ light).
- ✔ Radio or infotainment system issues.
- ✔ Horn honking unexpectedly or not working at all.
Installation and Post-Install Procedures
Installation is straightforward for a DIYer with moderate experience or any professional technician. After the new module is installed, some vehicles may require simple relearn procedures to sync the new BCM with other vehicle systems. These may include:
- Airbag System Sync: If the airbag light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control function, a brake pedal position sensor recalibration might be necessary.
There is no core charge for this part. You can keep your old module.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the instrument cluster.
How does the VIN programming work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this information to load the correct software and vehicle-specific settings onto the BCM before we ship it to you.
Is this a plug-and-play part?
Because it comes pre-programmed to your VIN, it is designed to be as close to plug-and-play as possible. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brakes, which can be performed by a qualified technician with a scan tool.
