Programmed 2008-2012 Express 1500 BCM 25934762 | Body Control Module

Restore Your Van’s Electrical System with a Reliable Solution

Is your 2008-2012 Chevy Express 1500 acting possessed? Flickering lights, malfunctioning power windows or locks, a security system that won’t cooperate, or even a frustrating no-start condition can often be traced back to one component: a failing Body Control Module (BCM). As the central command for your van’s body electronics, when the BCM goes down, it can create a cascade of baffling and intermittent problems. In my 20+ years of diagnostics, I’ve seen how a faulty BCM can turn a dependable workhorse into a source of constant headaches. This isn’t just an inconvenience; for a work van, downtime means lost income.

This replacement Body Control Module is the definitive fix for those issues. We take the guesswork and hassle out of the repair by pre-programming the module specifically for your vehicle. Simply provide your VIN during checkout, and our technicians will flash the unit with the latest GM software updates. This ensures that when the part arrives, it’s ready for a straightforward installation, getting your Express van back on the road and working as hard as you do.

Diagnosing a Faulty Body Control Module

• ✔ Power windows or door locks operating erratically or not at all.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ The security system or keyless entry failing to work correctly.
• ✔ Warning lights on the dash illuminating for no reason (e.g., ABS, Airbag).
• ✔ The vehicle failing to start, accompanied by a security light.
• ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
• ✔ Wipers or the horn activating unexpectedly.

Your Straightforward BCM Installation Guide

1. ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
2. ✔ Locate the BCM: On the 2008-2012 Express Van, the Body Control Module is typically located in the center dash area, often accessible by removing lower dash panels.
3. ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
4. ✔ Install the New Module: Mount the new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, making sure they click into place.
5. ✔ Reconnect Power: Reattach the negative battery terminal.
6. ✔ Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note that some vehicles may require additional relearn procedures as outlined in our post-install notes.

Post-Installation Procedures: What to Expect

While we program the BCM to your VIN for a near plug-and-play experience, some vehicle systems may require a final handshake. Be aware of the following potential procedures:

• Airbag System Sync: If the airbag light is on 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 recalibration might be necessary to ensure brake lights and stability control function correctly.
• 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. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.
