Frequently Asked Questions
How do I provide my VIN number for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the BCM specifically for your vehicle before we ship it to you. This ensures compatibility and proper function.
Will this BCM require any additional procedures after installation?
In some cases, post-installation procedures may be necessary. The most common are an ‘Airbag System Sync’ (if the airbag light is on) or a ‘Brake Pedal Position Relearn’. These procedures typically require a professional-grade scan tool to complete.
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories not related to the engine. This includes power windows, locks, lights, wipers, the security system, and more. When it fails, these systems can behave erratically.
Is this a brand new part?
This is a high-quality, fully tested component that is guaranteed to perform to OEM standards. It is prepared with the latest vehicle-specific software to ensure reliable, long-term operation for your 2008-2012 Savana 3500 Body Control Module.
