What is a Theft Detection System in the Chevy Cruze?

Just like the name sounds, the theft detection system is there to detect and prevent theft or breaking into your Chevy Cruze. It is a combination of internal and external sensors that detect when your car is being broken into or moved.

What Triggers Theft Detection System Errors?

The main culprit of a false trigger of the service theft deterrent erroneously appearing is a faulty or dead battery. When your battery charge gets too low, it will trigger the error message to appear.

When you see this, the first thing you will need to check is the battery. In other cases, it may have to do with the key being faulty.

Another simpler way is to do a manual reset. It can be argued that this step should actually go first. For this process, you will need to be in the driver’s seat of your car.

With the door closed, press the unlock button on the driver’s side door. Next, open the door and step out of your vehicle, and with the door still closed, press the lock button on the driver-side door and close it. This simple process should reset the error message.
