Restore Full Functionality to Your GM Vehicle
Are you battling bizarre and frustrating electrical problems in your GMC Savana, Chevy Express, or other compatible GM vehicle? Issues like malfunctioning power windows, erratic dashboard lights, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, part number 15880684, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We had a 2011 Savana 2500 work van come into the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome lights wouldn’t work, and the power locks were completely unresponsive. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a costly trip to the dealer for a new module and programming fees, we installed one of our VIN-programmed units. The van was back to normal in under an hour, saving the owner significant downtime and expense.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ Headlights, taillights, or interior lights behaving erratically.
- ✔ Key fob not working or vehicle security system faults.
- ✔ Radio or climate control system malfunctions.
- ✔ Vehicle failing to start due to anti-theft system engagement.
The Plug-and-Programmed Solution for Your Savana 2500 Body Control Module
Replacing a BCM used to mean a trip to the dealership for expensive parts and labor-intensive programming. Our process simplifies this repair. When you purchase this module, you provide us with your vehicle’s VIN. We then flash the BCM with the latest official GM software specific to your vehicle’s configuration. This ensures that when you receive the part, it’s ready for installation with minimal post-install steps. This is a direct-fit replacement for a wide array of GM vehicles, solving complex electrical issues without the dealership hassle. This Savana 2500 Body Control Module is your key to a reliable and straightforward repair.
Post-Installation Requirements
While our VIN programming handles the majority of the setup, some vehicles may require additional steps after installation. These are simple procedures for any qualified technician with a professional scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn 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 guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that manages and controls many of the electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
Is this part truly plug-and-play?
It’s as close as it gets. We program the module to your VIN before shipping, which handles the most critical software setup. However, as noted, some vehicles may require minor additional relearn procedures (like for the airbag or brake pedal sensor) with a scan tool after installation.
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 the module until we receive and program it with your VIN.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is a core component of the vehicle’s anti-theft system. A faulty BCM is a very common cause of security system errors and no-start conditions.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
