Normal Operation
The parking aid system is enabled when the ignition switch is in the RUN position and REVERSE (R) gear is selected. The parking aid module calculates the distance to an object by the use of 4 ultrasonic sensors mounted in the rear bumper. The parking aid sensors can detect obstructions in the path behind the vehicle. A 750 Hz variable warning tone is generated from a parking aid speaker. The parking aid speaker increases the warning tone rate as the vehicle gets closer to an obstacle. If no objects are present, the parking aid distance PIDs should read 255 cm (100 in).

DTC C1701 - is a continuous and on-demand DTC that sets if the parking aid module senses an internal failure in the left rear outer sensor.

DTC C1704 - is a continuous and on-demand DTC that sets if the parking aid module senses an internal failure in the right rear outer sensor.

DTC C1707 - is a continuous and on-demand DTC that sets if the parking aid module senses an internal failure in the left rear inner sensor.

DTC C1710 - is a continuous and on-demand DTC that sets if the parking aid module senses an internal failure in the right rear inner sensor.
