2007-2012 Acadia BCM 15948439 Body Control Module | Cloning Service

Restore Full Electrical Function to Your 2007-2012 GMC Acadia

If your 2007-2012 GMC Acadia is plagued by bizarre electrical issues, a failing Body Control Module (BCM) is the likely culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect vehicle security and safety. We offer a reliable, straightforward solution: a professionally prepared BCM with your vehicle’s data cloned to it, ensuring a seamless and effective repair.

This is not just a part in a box. It’s a comprehensive service. After your purchase, you’ll send us your original BCM. Our technicians will extract the critical vehicle-specific data—including key programming, security information, and optional feature settings—and transfer it directly onto this replacement module. The result is a true plug-and-play component, saving you from the time, cost, and hassle of a dealership visit for programming.

Common Signs of a Failing Acadia BCM

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ The security system or keyless entry malfunctioning, or the alarm sounding randomly.
• ✔ The instrument cluster displaying incorrect information or warning lights that won’t turn off.
• ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in other modules.
• ✔ In severe cases, a no-start condition where the BCM fails to recognize the key.

A Straightforward Guide to BCM Installation

1. ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. ✔ Locate the BCM: In the 2007-2012 GMC Acadia, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
3. ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. ✔ Install the New Module: Seat your new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
5. ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions: lights, locks, windows, radio, etc., to confirm the repair.

Important Post-Installation Information

While our cloning service makes this a plug-and-play repair, some vehicle systems may require a final handshake to fully integrate the new module. Please be aware of the following:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade diagnostic tool. This is only necessary if the light appears.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
• Professional Guidance: Always refer to a factory service manual or consult a qualified technician if you are unsure about any step. Your original module will be returned with the replacement unit; we do not keep cores.
