Restore Your Van’s Electrical System with a Plug-and-Play Solution
If you’re dealing with baffling electrical issues in your GM van—flickering lights, a dead instrument cluster, or a security system that has a mind of its own—you’re not alone. As a technician with over two decades of experience, I’ve seen these exact problems hundreds of times. The culprit is almost always a failing Body Control Module (BCM). It’s the central hub for your vehicle’s body electronics, and when it goes, it can create a cascade of frustrating, hard-to-diagnose symptoms. This isn’t just an inconvenience; it can affect safety systems and leave you stranded.
Forget the expensive trip to the dealership and the hassle of programming. We offer a reliable, straightforward fix. This Body Control Module, compatible with part number 15093910, arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This ensures seamless integration and restores your van’s original functionality right out of the box.
A Technician’s Notebook
I remember a 2011 Savana work van that came into my shop. The owner was at his wit’s end. The van would randomly not start, the radio would cut out, and the interior lights would pulse. He’d already replaced the battery and checked the alternator. After connecting my scan tool, I saw multiple communication loss codes (U-codes) pointing to the BCM. We installed one of our VIN-programmed modules, and in under an hour, every single ghost in that machine was gone. It’s a common failure, but thankfully, it’s a simple fix with the right part.
Common Signs of a Failing BCM
A faulty BCM can manifest in numerous ways. If your van is showing any of these signs, a replacement is likely the solution:
- ✔ Unpredictable power windows, door locks, or interior/exterior lighting.
- ✔ The security or anti-theft system preventing the engine from starting.
- ✔ Horn honking or alarm sounding randomly.
- ✔ Inaccurate or non-functional gauges on the instrument panel.
- ✔ Warning lights for the airbag (SRS) or anti-lock brakes (ABS) staying on.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
- ✔ A/C system not functioning correctly.
A Straightforward Guide to BCM Installation
Installing your new 2008-2012 Savana 1500 BCM is a manageable job for a confident DIYer or any professional mechanic. For the Savana, it’s typically located behind the center dash panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Access the Module: Carefully remove the necessary dash trim panels to gain access to the BCM. In most Savana and Express vans, this involves removing sections of the center dash or glove box area.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test functions like lights, windows, and locks to confirm operation.
Important Post-Installation Steps
While our programming handles the heavy lifting, some GM vehicles require a final handshake between modules after installation. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag 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 required to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to return your old BCM. There is no core charge or fee associated with this purchase.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for specific instructions related to your model.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the module. Simply provide your vehicle’s 17-digit VIN during or after checkout, and we will flash the BCM with the latest GM software for your specific vehicle. It arrives ready for installation.
Is this a simple plug-and-play installation?
For most vehicles, yes. Once you install the module, your vehicle should start and run with all body functions restored. In some cases, as noted above, minor relearn procedures for the airbag or brake systems may be required using a professional scan tool.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, the airbag system (SDM) may need to be synced with the new BCM using a scan tool to turn the light off. This is a standard security procedure on GM vehicles.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module or dispose of it responsibly.
How do I provide my VIN?
You can enter your VIN in the notes section during checkout or send it to us in a message after you place your order. We cannot program and ship your BCM without it.
