Code C1702 Ford Description

The parking aid system detects objects behind the vehicle when the vehicle is in REVERSE. The parking aid module does this by calculating the distance to an object by the use of 4 ultrasonic sensors mounted in the rear bumper. The ultrasonic field is emitted in a semicircular area around the rear of the vehicle. The parking aid sensors can detect objects approximately 1.8 m (5.9 ft) to the rear of the vehicle, 46 cm (18 in) to the rear side of the vehicle, and 16 cm (6 in) above ground. A 750 Hz variable warning tone is generated from a parking aid speaker attached to the parking aid module. The parking aid speaker increases its warning tone rate as the vehicle gets closer to an obstacle. When an object is detected within 25 cm (10 in) of the sensors, the warning tone becomes continuous.
The parking aid system is enabled when the ignition switch is in the RUN position and REVERSE is selected. The system can be disabled through the message center RESET switch located in the instrument cluster. The parking aid menu is displayed until the transmission is taken out of REVERSE. While the menu is displayed, pressing the message center RESET switch changes the parking aid system status to OFF.
The parking aid system is disabled if a fault is detected in 1 of the 4 sensors, the parking aid speaker, or the parking aid module. This will be indicated by the parking aid disabled warning CHECK BACKUP AID displayed in the message center. The parking aid module is on the International Standards Organization (ISO) 9141 network and can be diagnosed with a diagnostic tool.
