PTS Sensor 3 - Signal Shape Waveform Failure

Description

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.
