Programmed 2008-2012 Express 2500 BCM | Replaces Part 15093910

Restore Your Van’s Electrical Sanity

Are you dealing with a cascade of bizarre electrical issues in your Chevy Express or GMC Savana van? One moment the power locks don’t work, the next the interior lights are flickering, and then the security light prevents it from starting. As a technician with over 20 years of experience, I’ve seen this exact scenario hundreds of times. The culprit is almost always a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics.

This isn’t just a replacement part; it’s a complete, hassle-free solution. We take the biggest headache out of the repair by programming this module specifically to your vehicle’s VIN before it ever leaves our facility. This means it arrives at your door with the latest GM software updates, ready for installation. You get to skip the expensive trip to the dealership for programming, saving you significant time and money. This is the reliable fix you need to get your workhorse van back in service.

Is Your Express Van Showing These BCM Failure Signs?

A failing BCM can cause a wide range of confusing symptoms. If your van is experiencing any of the following, a faulty module is the likely cause:

• ✔ Power windows, door locks, or mirrors operating erratically or not at all.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ The anti-theft or security system acting up, causing a no-start condition.
• ✔ Intermittent operation of the radio or climate controls.
• ✔ False warning lights on the instrument cluster (e.g., ABS, Airbag).
• ✔ Diagnostic trouble codes related to communication loss, such as U0140, U0155, or other U-codes.

Your Straightforward BCM Installation Guide

Installing your new 2008-2012 Express 2500 BCM is a manageable job for a DIYer or any professional technician. While the exact location can vary slightly, it’s typically found in the center dash area on Express and Savana vans.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning work on any electronic components.
2. Locate the BCM: On most Express/Savana vans, you’ll need to remove trim panels around the center dash or glove box area to access the module.
3. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
4. Install the New Module: Mount the new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
5. Power Up & Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, etc.
6. Perform Relearn Procedures: As noted below, certain systems like the airbag or brake pedal position sensor may require a recalibration procedure with a capable scan tool if a warning light is present.

Important Notes on Post-Installation Procedures

Because this module communicates with multiple vehicle systems, some additional steps may be required after installation:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used 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 needed to ensure correct brake light and traction control operation.
• No Core Charge: You can keep your old module. There is no core charge and no need to send the original part back to us.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified mechanic for your specific model’s procedures.
