- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ The instrument cluster displaying incorrect information or warning lights randomly illuminating.
- ✔ The vehicle failing to start, accompanied by a security light on the dash.
- ✔ HVAC (heating and air conditioning) controls being unresponsive.
- ✔ Communication errors when a mechanic tries to scan the vehicle’s computer systems.

Post-Installation Information
While our programming covers the essential functions for a plug-and-play installation, some vehicle systems may require a ‘relearn’ or ‘sync’ procedure after the new BCM is installed. This is a normal part of the process. The most common procedures are:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does a Body Control Module do on my Savana Van?
The BCM acts as the brain for your van’s electronic accessories. It controls functions like power windows, locks, lights, security system, wipers, and the instrument cluster, ensuring they all work together as intended.
Why do you need my VIN number?
Your VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your van’s specific options and features. This ensures the module works correctly right out of the box, eliminating the need for a trip to the dealer.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical installation is typically straightforward. The BCM is usually located under the dashboard. Since we pre-program the unit, the most difficult part of the job is already done for you.
Will this fix my ‘Service Theft System’ message?
A faulty BCM is a very common cause of security system problems, including the ‘Service Theft System’ message and no-start conditions. Replacing it with our programmed module is a very effective way to solve these issues.
What if my airbag light comes on after I install it?
This is not uncommon. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to turn the light off.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
