B128E-11-PTS SENSOR 1 - CIRCUIT SHORT TO GROUND

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

THEORY OF OPERATION

The Park Assist Sensors are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the Park Assist Module 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. Since Chrysler Group vehicles use only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.

WHEN MONITORED

Vehicle in reverse.

During the self-test while vehicle is in drive between 11 mph (18 km/h) and 25 mph (40 km/h).

SET CONDITION

The Park Assist Module detects a short to ground on the Park Assist Sensor Signal circuit.

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

The Park Assist Sensors are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the Park Assist Module 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. Since Chrysler Group vehicles use only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

The Park Assist Sensors are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the Park Assist Module 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. Since Chrysler Group vehicles use only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

The Park Assist Sensors are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the Park Assist Module using a dedicated serial bus communication circuit.

The Park Assist Sensors are ultrasonic transceivers that are completely controlled by the Park Assist Module. The sensors transmit and receive ultrasonic signals. Each sensor has a voltage, signal, and return circuit to the module. The sensors communicate with the Park Assist Module 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. Since Chrysler Group vehicles use only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.
