Programmed 2008-2012 Savana 1500 BCM | Body Control Module 15921352

Restore Your Van’s Electrical Functions with a Reliable, Pre-Programmed BCM

If your 2008-2012 Savana 1500 Van is acting possessed—with flickering lights, malfunctioning power locks and windows, or a security system that has a mind of its own—you’re likely dealing with a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can cause some of the most frustrating and hard-to-diagnose electrical issues. It’s the central command center for your vehicle’s comfort and security features, and when it goes, it can feel like everything is breaking at once.

Forget the expensive trip to the dealership and the hassle of coordinating programming. We offer a straightforward solution: a high-quality BCM that arrives at your door already programmed to your van’s specific Vehicle Identification Number (VIN). Simply provide your VIN at checkout, and our experts will flash the module with the latest GM software updates. This ensures it communicates perfectly with your vehicle’s other systems right out of the box, saving you significant time and money.

Common Signs of a Failing BCM

A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your likely solution:

• ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights).
• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ The security system acting up, causing alarm issues or no-start conditions (common U-codes like U0100, U0140).
• ✔ Instrument cluster gauges behaving strangely or warning lights staying on.
• ✔ The radio or HVAC controls are unresponsive.
• ✔ A parasitic battery drain that kills your battery overnight.

A Straightforward Guide to Installation

Installing your new 2008-2012 Savana 1500 BCM is a manageable job for a confident DIYer or any professional mechanic. In most Savana and Express vans, the BCM is located in the center dash area.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Access the Module: You will likely need to remove some dash trim panels around the center console or glove box area to gain access to the BCM.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. 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.
5. Reconnect Power: Reattach the negative battery terminal.
6. Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform additional procedures as noted below. For many, the vehicle will function correctly immediately.

Important Post-Installation Notes

While our VIN programming handles the critical setup, some vehicle systems may require a ‘handshake’ with the new BCM. These procedures typically require a bi-directional scan tool.

• Airbag System Sync: If your airbag warning light is on after installation, a professional will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
• 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.

Disclaimer: We always recommend consulting a factory service manual for your specific vehicle. No core charge is required; you can keep your old part.
