Programmed 2008-2012 Savana 1500 Van BCM 15880684 | Body Control Module

Restore Your Van’s Electrical System with a Reliable, Programmed BCM

As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a dependable workhorse like a 2008-2012 Savana 1500 Van into a source of constant frustration. Are you dealing with flickering lights, power windows and locks with a mind of their own, or a security light that won’t turn off? These aren’t just annoyances; they’re classic signs that your vehicle’s electronic nerve center is failing. The BCM is responsible for managing a huge range of your van’s comfort and security features, and when it goes, the symptoms can be baffling.

This isn’t just a replacement part; it’s a complete solution. We take the guesswork and extra cost out of the repair by programming this BCM specifically for your vehicle using your VIN. This means it arrives at your door with the latest GM software updates already installed, ready for a straightforward installation. You get to skip the expensive trip to the dealership for programming, saving you both time and money.

Is Your Vehicle Showing These Symptoms?

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

• ✔ Intermittent or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights behaving erratically (staying on or not turning on).
• ✔ The security or anti-theft light is illuminated on the dash, possibly causing a no-start condition.
• ✔ Inaccurate or dead gauges on the instrument cluster.
• ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
• ✔ Key fobs that have stopped working.

A Straightforward Guide to BCM Installation

Replacing the BCM in most of these GM vans and SUVs is a manageable job for a confident DIYer. While the exact location varies slightly by model, the process is generally similar.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
2. Locate the BCM: On the Savana/Express vans, the BCM is typically found in the center dash area. On other models like the Tahoe or Acadia, it’s often on the left side of the dash or under the steering column. A quick search for your specific model will confirm its location.
3. Access the Module: You may need to remove a few plastic trim panels to gain clear access to the BCM. A simple trim removal tool and a screwdriver are usually all that’s needed.
4. 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.
5. Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a ‘click’ when they are properly seated.
6. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.

Important Post-Installation Notes

Because this BCM is pre-programmed, most functions should work immediately. However, depending on your vehicle’s specific configuration, a couple of simple relearn procedures may be necessary. These are not signs of a faulty part but are standard security handshakes between modules.

• Airbag System Sync: If your airbag warning 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 relearn may be required to ensure correct brake light operation and traction control function.

Our Promise: This module requires no core charge! You can keep your old part without any extra fees or the hassle of shipping it back.
