B1296-11






B1296-11-PTS SENSOR 9-CIRCUIT SHORT TO GROUND





For a complete wiring diagram, refer to the Wiring Information.

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:
While the vehicle is in reverse for speeds less than 10 mph (16km/h).

- Set Condition:
Sensor ring down time is too short (700 micro secs).
