Programmed 2008-2012 Express 1500 BCM Body Control Module 15093910

Restore Command of Your Van’s Electronics

Is your Chevrolet Express van acting possessed? Flickering lights, malfunctioning power windows, a temperamental security system, or strange warning messages on the dash are classic signs that your Body Control Module (BCM) is failing. As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. In my 20+ years of diagnostics, I’ve seen BCM failure turn a reliable workhorse into a source of constant headaches. Communication codes like U0140 are often the first clue a technician sees, pointing directly to a breakdown in this critical component.

This isn’t just a replacement part; it’s a complete solution. We take the guesswork and hassle out of the repair by programming this module specifically for your vehicle using your VIN. This ensures all your factory-installed options work correctly right out of the box. We load the latest GM software, which often includes stability improvements over the original programming. You get a reliable fix that restores your van’s functionality without the expensive trip to the dealership for programming.

Is Your Vehicle Showing These Symptoms?

• ✔️ Power windows, locks, or mirrors work intermittently or not at all.
• ✔️ Interior or exterior lights flicker, stay on, or won’t turn on.
• ✔️ The anti-theft or security system engages randomly, preventing the van from starting.
• ✔️ The instrument cluster displays false warnings or inaccurate readings.
• ✔️ Communication-related Diagnostic Trouble Codes (DTCs) are present, such as U0140, U0155, or other U-codes.
• ✔️ Wipers or the horn activate without input.

Your Straightforward BCM Installation Guide

For the 2008-2012 Express 1500 Van, the BCM is typically located in the center dash area. While the exact position can vary slightly, the replacement is manageable for a DIYer with basic tools.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. Access the Module: You will likely need to remove a few dash panels to get to the BCM. On Express vans, it’s often behind the lower center instrument panel trim.
3. Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt the old BCM and remove it from its mounting bracket.
4. Install the New BCM: Mount your new, pre-programmed module in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, wipers, etc.

Important Post-Installation Notes

While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. Specifically, be aware of the following:

• Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be done with a professional scan tool. This is only necessary if the light appears.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and traction control operation.
• No Core Charge: You are not required to return your old module. This saves you the time and expense of a core return.
