Programmed 2007-2012 Acadia BCM 25847589 | Body Control Module

Restore Full Electrical Control to Your GM Vehicle

Are you battling a storm of bizarre electrical issues in your 2007-2012 GMC Acadia? Flickering dash lights, power windows with a mind of their own, or a security system that randomly immobilizes your vehicle are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. In my 20+ years of diagnostics, I’ve seen how a single failing module can mimic a dozen different problems, leading owners down a rabbit hole of expensive, unnecessary repairs.

This isn’t just a replacement part; it’s a direct solution. We take the biggest headache out of the repair process: programming. Simply provide your vehicle’s VIN at checkout, and our technicians will flash this BCM with the latest GM software specific to your Acadia. It arrives at your door ready to be installed, saving you a costly trip to the dealership and the hassle of specialized programming tools. This is the most efficient way to get your vehicle back to 100% functionality.

Is Your Vehicle Showing These Symptoms?

• ✔ Intermittent or non-working power windows, door locks, or mirrors.
• ✔ Dashboard lights flickering or warning messages appearing randomly (e.g., “Service Stabilitrak,” “Service Airbag”).
• ✔ The anti-theft or security system preventing the engine from starting.
• ✔ Erratic behavior from interior or exterior lighting.
• ✔ Climate control functions not responding correctly.
• ✔ Communication error codes (U-codes) stored when scanned.

A Straightforward Guide to BCM Installation

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
2. Locate the BCM: On the 2007-2012 Acadia, the BCM is typically located under the driver’s side of the dashboard, to the left of the steering column. You may need to remove a lower dash panel for access.
3. 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.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
5. Reconnect Power: Re-attach the negative battery terminal.
6. Critical Final Steps: Proceed immediately to the post-installation procedures noted below. The vehicle may not operate correctly until these are completed.

Important Post-Installation Requirements

After installing your new BCM, a few final steps are essential for safety and proper operation. These procedures sync the new module with your vehicle’s other critical systems. You will need a bi-directional scan tool or to visit a qualified mechanic to perform these functions.

• Airbag System Sync: To clear the airbag warning light and ensure the system is active, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This is a non-negotiable safety step.
• Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position Sensor to be recalibrated. This ensures the brake lights and stability control system receive accurate input.
