Circuit/System Description

The parking assist system is enabled and disabled through the parking assist switch. When enabled, the parking assist indicator will illuminate.

The switch and indicator are connected to the parking assist control module. The parking assist control module supplies a reference voltage to the parking assist switch. When the switch is pressed, the signal circuit is grounded. The parking assist control module can control the park assist indicator by grounding the control circuit to illuminate the LED which indicates that the system is enabled.

The parking assist control module supplies a reference voltage and a low reference to the object sensors. The sensors will return a signal based on the reflections from objects within range of the sensors.

When an object is detected, the parking assist control module will send serial data to the radio and memory seat module to provide either an audible alert or haptic feedback through the active safety seat. The driver can select between audible or haptic alerts in the vehicle personalization menu.
