2007-2009 SRX Body Control Module 15837419 | Cloning Service

Restore Full Electrical Function to Your Cadillac SRX

If you’re dealing with baffling electrical issues in your 2007-2009 Cadillac SRX—like power windows with a mind of their own, flickering dash lights, or accessories that work intermittently—you’re likely facing 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 luxury vehicle into a source of daily frustration. The BCM is the central command for your car’s body electronics, and when it fails, it creates chaos. This isn’t just an inconvenience; it can affect safety systems and your vehicle’s security.

We offer a straightforward, reliable solution. This replacement BCM is meticulously prepared for your specific vehicle. By providing your VIN during checkout, you receive a module that is programmed with the latest GM software, ensuring seamless communication with your SRX’s other systems. This eliminates the need for a costly trip to the dealership for programming, saving you both time and money. For those who want to retain every specific setting from their original unit, our Cloning Service transfers the exact data from your old module to the new one, making the swap as simple as possible.

Is Your Cadillac Showing These Symptoms?

• ✔ Power windows or door locks operating erratically or not at all.
• ✔ Interior or exterior lights flickering, staying on, or not turning on.
• ✔ The security system acting up or preventing the car from starting.
• ✔ Dashboard warning lights appearing for no clear reason.
• ✔ Communication error codes stored, such as U0140, U0155, or other U-codes.
• ✔ Wipers, radio, or climate control functions behaving unpredictably.

A Straightforward Guide to Installation

1. ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. ✔ Locate the BCM: On the 2007-2009 SRX, the Body Control Module is typically found on the driver’s side, under 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 pressed to release. 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. Securely plug in all the electrical connectors, ensuring they click into place.
5. ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition on and test all body functions—windows, locks, lights, wipers, etc.—to confirm proper operation.
6. ✔ Perform Relearn Procedures: If necessary, perform the post-installation procedures detailed below, such as the Airbag System Sync, to clear any remaining warning lights.

Post-Installation Steps & Considerations

After installing your new BCM, some vehicle systems may require recalibration. This is a normal part of the process. The most common procedures are:

• Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM and the Sensing and Diagnostic Module (SDM) need to be electronically introduced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
• Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure the brake lights and traction control system function correctly.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.
