Restore Full Functionality to Your GM Vehicle

Is your work van or family SUV plagued by bizarre electrical issues? Flickering lights, malfunctioning power locks, a security system that acts up, or an instrument cluster that seems to have a mind of its own? These are classic signs of a failing Body Control Module (BCM). For a hard-working vehicle like a 2008-2012 Savana 2500 Van, this isn’t just an annoyance—it’s a reliability issue that can cost you time and money. This replacement BCM, part number 15872421, is the definitive solution to restore your vehicle’s electronic stability.

The Power of Our Plug-and-Play Cloning Service

Forget about expensive dealership visits and complex programming tools. Our unique cloning service makes this repair straightforward. Here’s how it works: After your purchase, you’ll send us your original, faulty BCM. Our expert technicians will then extract the specific vehicle data—including key information and security protocols—and transfer it directly onto this replacement module. We then ship both your original module and the ready-to-install replacement back to you. The result is a true plug-and-play part, perfectly matched to your vehicle’s VIN and options, with no further programming needed on your end. This is the most efficient way to get a reliable 2008-2012 Savana 2500 BCM replacement.

Is Your Vehicle Showing These Symptoms?

• ✔ Erratic or non-functional interior and exterior lights
• ✔ Power windows, mirrors, or door locks working intermittently or not at all
• ✔ The security system light stays on or the alarm randomly triggers
• ✔ Instrument cluster gauges behaving erratically or going dark
• ✔ Communication error codes (U-codes) stored in the system
• ✔ Intermittent no-start condition where the engine won’t crank

A Straightforward Guide to Installation

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. ✔ Locate the BCM: On most Savana and Express vans, the BCM is located behind the center dash area, often accessible by removing the lower dash panels or glove box.
3. ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. ✔ Install the Replacement: Mount the new, cloned BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
5. ✔ Reconnect Power: Reattach the negative battery terminal.
6. ✔ Final Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. Note that some vehicles may require the post-installation procedures mentioned below.

Important Post-Installation Information

With a cloned module, most vehicles will be ready to go immediately. However, on certain GM models, a couple of quick relearn procedures may be necessary if you notice specific warning lights. These often require a professional bidirectional scan tool.

• Airbag System Sync: If your airbag warning light is on after the swap, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the two modules.
• Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Always consult your vehicle’s service manual or a professional technician if you are unsure about any step of the process.
