Installation and Post-Install Notes
Installation is straightforward. On the Savana Van, the BCM is typically located in the center dash area. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. While the module is pre-programmed, some vehicles may require a simple relearn procedure after installation:
- Airbag System Sync: If the airbag light is on after install, 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 recalibration might be needed to ensure correct brake light operation.

Frequently Asked Questions
What does a Body Control Module do on a Savana Van?
The BCM acts as the central computer for your van’s body electronics. It controls non-engine related functions like lights, power windows and locks, wipers, the security system, and the climate controls.
Is this 2004-2007 Savana 3500 BCM truly plug-and-play?
Yes, it is. We pre-program the module to your vehicle’s VIN before shipping. This means you can install it without needing to visit a dealership for additional programming, saving you time and money.
Where is the BCM located on a 2004-2007 Savana 3500?
For the Savana and Express vans, the BCM is typically found behind the center dash panel, making it accessible for replacement.
What happens if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be performed by a technician with a professional-grade scan tool.
Do I need to send my old BCM back?
No, there is absolutely no core charge or return required for this part. You can keep your old module without any penalty.
