Installation and Post-Install Notes
While this Savana 3500 Body Control Module is designed for straightforward installation, some vehicles may require additional steps after the new part is connected. In some cases, an ‘Airbag System Sync’ may be needed if the airbag warning light appears. This procedure, known as ‘Setup SDM Primary Key in BCM,’ requires a professional-grade scan tool. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control operation. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and instrument panel gauges.
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN during checkout, and it will arrive ready to be installed, saving you time and money.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
What if the airbag light is on after I install the BCM?
If the airbag light illuminates, it means the BCM needs to be synced with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional diagnostic tool.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
