Theory Of Operation
The Park Assist Sensors are ultrasonic transceivers that are controlled by the Park Assist Module (PAM). The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the PAM using a dedicated serial bus communication circuit.
NOTE:
The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle.
