Restore Full Functionality to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2007-2012 GMC Acadia? Flickering lights, malfunctioning power windows, or a security system that acts on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and unpredictable problems. This isn’t just an annoyance; it can impact your vehicle’s safety and reliability. We offer a direct, dependable solution: a replacement BCM, part number 25847588, that arrives at your door programmed specifically for your vehicle.
Case Study: A Tricky Diagnosis
A customer’s 2011 Acadia came into the shop last month with a laundry list of bizarre symptoms. The radio would turn off randomly, the liftgate wouldn’t open with the remote, and the ‘Service Stabilitrak’ light was on. They had already replaced the battery and checked all the fuses. After connecting my diagnostic scanner, I saw multiple communication loss codes pointing to the BCM. The internal circuitry was failing, causing data corruption on the vehicle’s network. Installing a VIN-programmed 2007-2012 Acadia Body Control Module like this one resolved all issues instantly. It’s a common failure point I’ve seen dozens of times on these platforms.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The anti-theft system preventing the car from starting or the alarm sounding randomly.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Remote keyless entry failing to respond.
- ✔ Warning messages on the dash like ‘Service Airbag’ or ‘Service Stabilitrak’ that can’t be traced to a mechanical fault.
Your Straightforward Installation Guide
Replacing the BCM in your Acadia is a manageable job for a confident DIYer. The key is our VIN programming service, which eliminates the need for expensive dealer tools. Follow these general steps to get your vehicle back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning any electrical work.
- Locate the BCM: On the 2007-2012 Acadia, the Body Control Module is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- Remove Trim Panels: Carefully remove any plastic trim panels necessary to access the module. These are usually held in with clips and a few screws.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Post-Installation Procedures: Reconnect the battery. Crucially, you will need to perform two key procedures. First, the ‘Setup SDM Primary Key in BCM’ procedure is required to clear the airbag warning light. Second, a brake pedal position sensor recalibration may be necessary. Both tasks require a professional-grade diagnostic tool. If you are not equipped for this, a local repair shop can complete these final steps for you.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the brain for your vehicle’s comfort and convenience features. It controls functions not related to the engine, such as power windows, locks, interior/exterior lighting, security system, wipers, and more.
Why do you need my VIN number?
We require your Vehicle Identification Number (VIN) to program the BCM with the latest GM software specific to your vehicle’s factory-installed options. This ensures all features work correctly right out of the box and saves you a trip to the dealer for expensive programming.
Is this a simple plug-and-play installation?
The physical installation is plug-and-play. However, after installation, you must perform a ‘Setup SDM Primary Key’ procedure with a diagnostic tool to sync the BCM with the airbag system. Some vehicles also require a brake pedal sensor recalibration. These are critical safety steps.
Will this fix my ‘Service Airbag’ light?
If the light is caused by a faulty BCM, this part will resolve the root cause. However, you must perform the SDM key setup procedure after installation to turn the light off. The light will not go off on its own.
What happens if I install it without programming?
An unprogrammed BCM will not function correctly. It may cause more issues than it solves, as it won’t know which options your vehicle has (e.g., power liftgate, sunroof, specific lighting). Our pre-programming service is essential for proper operation.
