Is Your Savana Van Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable issues. Don’t let a faulty module keep your workhorse van off the road. This is the direct-fit, simple solution you need.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ Erratic dashboard gauges or warning lights (like the security or airbag light).
- ✔ The horn sounding unexpectedly or not working at all.
- ✔ Remote keyless entry failure.
- ✔ A no-start or no-crank condition where the engine won’t turn over.
- ✔ Communication errors when scanning with a diagnostic tool.
From the Diagnostic Bay
We had a 2011 Savana 2500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome lights would flicker while driving, and occasionally, it just wouldn’t start. The owner had already replaced the battery and checked the alternator. After hooking up our scanner, we saw multiple communication loss codes with various modules. All signs pointed to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The van started right up, and every single electrical gremlin was gone. It’s a textbook example of how a single failing module can wreak havoc on the entire vehicle.

Post-Installation Information
While this BCM is designed for a simple installation, some vehicles may require additional steps to ensure all systems function correctly. These are not programming steps but rather relearn or synchronization procedures that may be needed after the new module is connected.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary for correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does the Body Control Module do on my Savana Van?
The BCM is a computer that manages and controls many of your van’s non-engine related electronic functions. This includes power windows, power locks, the security system, interior and exterior lighting, wipers, and the horn.
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 part until we receive this information, as the programming is specific to your exact vehicle.
Is this part difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located in the center dash area. The main benefit of our service is that the complex programming is already done, making it a plug-and-play part.
Will I need to pay a core charge?
No. There is no core charge for this part. You can keep your original module.
What if my airbag light turns on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be synchronized with your vehicle’s existing airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a compatible high-end diagnostic scan tool.
