Is Your Savana Van Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a frustrating no-start condition, the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your van’s body electronics, and when it starts to fail, it can create a cascade of confusing and intermittent problems. This replacement Body Control Module, part number 25847589, is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We had a 2011 Savana 1500 work van come in that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and sometimes the power door locks wouldn’t respond. He had already replaced the battery and checked fuses, but the problems persisted. After a quick scan, we saw multiple communication errors pointing towards the BCM. Instead of spending hours trying to isolate a single wire, we installed a VIN-programmed BCM. The van was back to normal in under an hour, all electrical functions restored. It’s a classic case where replacing the central component saves time, money, and immense frustration.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Instrument cluster gauges behaving erratically or warning lights staying on.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ The vehicle failing to start, even with a good battery and starter.

Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require minor post-installation procedures for full system synchronization:
- Airbag System Sync: If your airbag warning light is illuminated 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 relearn may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a hub for these functions.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the specific software and settings for your van’s exact options. This makes the module plug-and-play and avoids a costly trip to the dealership for programming.
Is this BCM difficult to install?
For the Savana van, the BCM is typically located in the center dash area. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It is a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual.
Will this fix my ‘Service Airbag’ light?
If the light is caused by a faulty BCM, yes. However, after installation, the airbag system may need to be synced to the new BCM using a professional scan tool, as mentioned in the post-installation procedures.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
