Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
The side blind zone alert system uses two modules: The side object sensor module - left and the side object sensor module - right. The side object sensor module - left is the master and communicates with other control modules in the vehicle via the vehicle-wide serial data bus. The side object sensor module - left communicates with the side object sensor module - right on a private serial data bus. Internal fault detection is performed within the side object sensor module - left. No external circuit diagnosis is involved.
