An Expert’s Note for the Savana Owner
We know your Savana is your livelihood. We recently helped a plumbing contractor whose 2011 van was having intermittent starting issues and flickering headlights, making him late for jobs. The dealer quoted him over a thousand dollars and a two-day wait. We sent him this pre-programmed BCM overnight. He installed it himself in under an hour the next morning and was back on the road, serving his customers. That’s the difference this solution makes—it minimizes downtime and gets your essential tool back in service, saving you time and money.
Installation & Post-Install Notes
While installation is straightforward, some vehicles may require simple post-installation relearn procedures to sync with other vehicle systems. These can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine-related functions. This includes power windows, power locks, interior and exterior lighting, security system, wipers, and climate controls. When it fails, you experience a wide range of strange electrical issues.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the module to work in your specific van.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the physical replacement is typically straightforward. The BCM is usually located under the dashboard. The main benefit of our service is that the complex and dealer-required programming is already done, making the electronic side of the installation plug-and-play.
What if my airbag light is on after I install it?
This is a common occurrence. The new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with a professional-grade diagnostic tool.
Do I need to send my old BCM back?
No. This purchase has no core charge. You can keep, recycle, or dispose of your original module at your convenience, saving you time and return shipping costs.
