Programmed 2007-2012 Acadia BCM Body Control Module | Part #25847589

Tired of Bizarre Electrical Problems in Your GMC Acadia?

If you’re dealing with a 2007-2012 GMC Acadia that seems to have a mind of its own, you’re not alone. Power windows that won’t go up, interior lights that stay on, a security system that randomly activates, or a key fob that works intermittently are all classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable SUV into a source of constant frustration. It’s the central command center for all your vehicle’s comfort and convenience features, and when it starts to fail, chaos ensues.

Don’t let a faulty module dictate your driving experience. This isn’t just about annoyance; a failing BCM can also affect security and communication between other vital modules. The typical solution involves a costly trip to the dealership, a tow bill, and several hours of labor for diagnostics and programming. We offer a better, more direct solution.

Is Your Acadia Showing These BCM Failure Signs?

A failing BCM can cause a wide range of symptoms that may seem unrelated. If you’re experiencing any of the following, your BCM is the likely culprit:

• ✔ Erratic or non-functional power windows, locks, and mirrors.
• ✔ Interior or exterior lights that won’t turn on or off.
• ✔ The security system or alarm activating for no reason.
• ✔ Key fobs not being recognized or working intermittently.
• ✔ Warning messages on the dash like “Service StabiliTrak” or “Service Airbag.”
• ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
• ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.

A Straightforward Guide to Installation

Installing your new BCM is a manageable task for a confident DIYer. Since the programming is done, you just need basic tools and about an hour. The BCM in the 2007-2012 Acadia is typically located on the left-hand (driver’s) side of the dash, often behind the lower trim panel near the steering column.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all modules to power down completely.
2. Access the BCM: Remove the necessary lower dash panels and trim to gain clear access to the Body Control Module.
3. Disconnect the Old Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed to release them. Note their orientation.
4. Swap the Modules: Unbolt or unclip the old BCM from its mounting bracket and install the new, pre-programmed module in its place.
5. Reconnect Everything: Securely plug all the electrical harnesses back into the new BCM. You should hear a click as they lock into place. Reassemble the dash panels.
6. Final Steps & Re-sync: Reconnect the negative battery terminal. Your vehicle is now ready, but you must perform the critical post-installation procedures noted below.

Critical Post-Installation Procedures

After installing your new 2007-2012 Acadia BCM, a couple of final steps are required to ensure all systems operate correctly. These procedures ensure safety systems are properly initialized.

• Airbag System Reset: The airbag warning light will likely be on. You must use a compatible high-end diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes the security handshake between the new BCM and the airbag module (SDM).
• Brake Pedal Position Sensor Relearn: Some vehicles may require the Brake Pedal Position (BPP) Sensor to be recalibrated. This is also done with a diagnostic tool and ensures the brake lights and stability control systems function correctly.

Note: If you are not comfortable performing these relearn procedures, a local professional mechanic can typically complete them for you quickly.
