Kia Sorento (XM, 2011-2015) Service Manual / Body Electrical System / Rear Parking Assist System / System Overview

RPAS (Rear Parking Assist System) is an electronic driving aid that warns the driver to be cautious while parking or in low speed environments. The sensor uses ultrasonic waves to detect objects within proximity of the vehicle.

RPAS consists of four sensors which are detecting the obstacles and transmit the result separated into three warning levels, the first, second and third to IPM(BCM) by Lin communication. IPM(BCM) decides the alarm level by the transmitted communication message from the slave sensors, then operate the buzzer or transmits the data for display.
