Road speed signal • BCM (body control module) - Reverse gear engaged signal, vehicle configuration parameters, carmode and powermode • Transmission control unit - Gear selector position (automatic transmission) • Trailer module - Trailer connection status The parking aid module carries out self-check routines and when the parking aid is active and checks the parking aid sensor wiring for short or open circuits If a concern is detected, a diagnostic trouble code (DTC) is stored in a memory in the parking aid module and the rear parking aid sensors will be disabled until the DTC is cleared and the ignition cycled DTCs can be read using the Ford approved diagnostic tool through the data link connector (DLC) For additional information, refer to: Parking Aid Module (413-13 Parking Aid, Removal and Installation) Parking Aid Camera The wide angle lens camera is fixed in the in the rear Ford badge, on the tailgate It is connected to the rear view mirror It is not necessary to programme the camera after changing it 2011.50 Ranger G1449946en Parking Aid 413-13-4 413-13-4 DESCRIPTION AND OPERATION Rear parking aid sensors Rear outer parking aid sensor holder(s) body wiring harness Three pins provide for power supply, ground and signal lines to and from the parking aid module Rear outer parking aid sensor(s) Each parking aid sensor consists of the following: Rear inner parking aid sensor holder(s) Rear inner parking aid sensor(s) • a plastic housing • an aluminium membrane which contains a piezo electric disc • inner and outer clips to hold the sensor in the bumper assembly • a printed circuit board assembly Item Description The parking aid sensor consists of a sensor and a holder The holder makes sure that each parking aid sensor is correctly orientated in relation to its location in the rear bumper Each parking aid sensor has a three pin connector which connects with the front bumper wiring harness, which in turn is connected to the main 2011.50 Ranger The disc resonates at a frequency of ca 50kHz, producing the ultrasonic output The disc also receives the reflected echo signal from any objects within range G1449946en 413-13-5 Parking Aid 413-13-5 DESCRIPTION AND OPERATION Distance calculation Rear parking aid sensors The maximum detection range for the rear parking aid sensors is 1800 mm (70 inches) for the central 2011.50 Ranger parking aid sensors and 600 mm (23.5 inches) for the corner parking aid sensors G1449946en 413-13-6 Parking Aid 413-13-6 DESCRIPTION AND OPERATION Vehicles with parking aid 2011.50 Ranger G1449946en Parking Aid 413-13-7 413-13-7 DESCRIPTION AND OPERATION Item Description Parking aid module Body Control Module (BCM) Reverse gear switch Instrument cluster ABS sensor assembly ABS Trailer relay Rear parking aid sensor Rear parking aid sensor 10 Rear parking aid sensor 11 Rear parking aid sensor System Operation Parking Aid Camera CAUTIONS: sharp objects, fat solvents, wax or organic media Only use a damp cloth for cleaning If a high-pressure cleaner is used to wash the vehicle, the jet must only be aimed at the reversing camera briefly at a distance of at least 20 cm The reversing camera is sensitive to pressure The position and angle of the camera can be changed with increased pressure It is not necessary to programme the camera after changing it The reversing camera system essentially consists of a camera built into the rear Ford badge, which is linked to a display in the rear view mirror When the ignition is switched on and reverse gear is selected, the driver sees a video image of the area behind the vehicle on the rear view mirror display Guides integrated in the camera images show the distances to obstacles shown in the display The camera view is automatically disabled seconds after disengaging reverse gear Always keep the reversing camera free from dirt, ice and snow Do not clean with 2011.50 Ranger G1449946en 413-13-8 Parking Aid 413-13-8 REMOVAL AND INSTALLATION Parking Aid Module Removal NOTE: Removal steps in this procedure may contain installation details Passenger side Installation To install, reverse the removal procedure Refer to: Front Seat (501-10 Seating, Removal and Installation) Torque: 10 Nm 2011.50 Ranger G1449953en 413-13-9 Parking Aid 413-13-9 REMOVAL AND INSTALLATION Parking Aid Camera Removal NOTE: Removal steps in this procedure may contain installation details Installation To install, reverse the removal procedure 2011.50 Ranger G1449954en
