Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2007-2009 Cadillac SRX? Maybe the power windows have a mind of their own, the interior lights flicker, or you’re seeing strange warnings on the dash. These are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, a faulty BCM can turn your driving experience into a frustrating guessing game. In my 20+ years of automotive diagnostics, I’ve seen how a failing BCM can mimic a dozen other problems, leading to expensive and unnecessary repairs.
This replacement Body Control Module, part number 25910474, is the definitive solution. It’s not just a part in a box; it’s a complete service designed to get you back on the road with minimal downtime. We handle the critical programming for you through our professional cloning service. Simply send us your original BCM, and we will transfer all the vital, vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module, eliminating the need for a costly trip to the dealership for programming.
A Technician’s Notebook: The SRX with a Ghost
A customer brought in their ’08 SRX with a list of complaints that sounded like a haunting: the radio would turn off randomly, the security light was on, and the driver’s side window wouldn’t go down. They’d already replaced the window switch and the battery. Diagnostics showed a flurry of communication error codes, specifically U0140 (Lost Communication with BCM). Instead of chasing each symptom, we went straight to the source. The BCM’s internal circuits were failing. By providing a cloned 2007-2009 SRX Body Control Module, we had the vehicle fixed in an afternoon. The customer avoided hundreds in dealership programming fees and the headache of further misdiagnosis. This is a perfect example of how targeting the core problem with the right part saves time and money.
Common Signs of a Failing BCM
If your vehicle is exhibiting these symptoms, a faulty Body Control Module is a very likely culprit. A failing BCM often won’t store its own specific fault codes, but it will cause communication codes with other modules.
- âś” Erratic or non-functional power windows, door locks, and mirrors.
- âś” Interior or exterior lights staying on, flickering, or not working at all.
- âś” The security system acting up, causing no-start conditions or false alarms.
- âś” Horn sounding unexpectedly or not working when pressed.
- âś” Inaccurate or dead gauges on the instrument cluster.
- âś” Diagnostic trouble codes like U0140, U0155, or B1001.
Your Straightforward BCM Installation Guide
Installing your replacement BCM is a manageable job for a DIY enthusiast. For the 2007-2009 SRX, the BCM is typically located on the left-hand (driver’s) side of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work. Wait a few minutes to allow all modules to power down completely.
- Locate the BCM: On the SRX, you will likely need to remove the lower dash panel beneath the steering column to gain access. It’s a black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all wiring harnesses 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. Securely reconnect all wiring harnesses, making sure each one clicks into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, windows, locks, wipers, etc., to confirm the repair.
- Perform Relearns (If Needed): In some cases, you may need to perform a Brake Pedal Position relearn or an Airbag System sync if warning lights appear. See our FAQ for more details.

Frequently Asked Questions (FAQ)
What is a ‘Cloning Service’?
What is a ‘Cloning Service’?
Cloning is a process where we transfer the exact software and vehicle-specific data (like your VIN, security info, and mileage) from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, allowing for a simple plug-and-play installation without any additional programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the data. After you place your order, we will provide instructions for sending your part to us. We will return your original module along with the newly programmed replacement.
Is this a guaranteed fix for my 2007-2009 SRX Body Control Module issues?
If your vehicle’s symptoms match those of a failed BCM and the module has been professionally diagnosed as the fault, this part will resolve those issues. It restores the factory-intended operation of your vehicle’s body electronics.
What is the ‘Airbag System Sync’ mentioned in the procedures?
The BCM and the Sensing and Diagnostic Module (SDM, or airbag module) communicate. If the airbag warning light is on after installation, it means they need to be re-synced. This ‘Setup SDM Primary Key in BCM’ procedure requires a professional scan tool but is only necessary if the light appears.
Will I have to perform the Brake Pedal Position Relearn?
This procedure may be required on some models to ensure your brake lights and traction control system function correctly. It’s a simple recalibration that can often be done with a capable scan tool. Always consult a service manual for your specific vehicle’s requirements.
