Common Symptoms of a Failing BCM

- ✔ The security system acting up or preventing the vehicle from starting.

Installation and Post-Install Procedures
Replacing the Savana 3500 Body Control Module is a straightforward process. It is designed to be plug-and-play after we program it to your VIN. However, in some cases, additional steps with a professional diagnostic tool may be required to sync related vehicle systems:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific procedures.

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 electronic functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Do I need to get this module programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready for installation.
Where is the BCM located on my Savana Van?
On the 2008-2012 GMC Savana and Chevrolet Express vans, the BCM is typically located in the center of the dash area. Always confirm the location for your specific vehicle before beginning work.
What if my airbag light turns on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
