B1215 Rear Center Left Sensor Fault - General Information

Component Location





General Description

RPAS is a Rear Parking Assistant System. It has a supersonic sensor which radiates supersonic to rear side of the vehicle to detect supersonic reflected from an obstacle. It consist of 4 sensor and calculates distances between vehicle and obstacle if it detects reflected supersonic. BCM receive the signal of calculated distances by LIN communication. It warns being obstacle to drivers through buzzer or displaying on cluster according to distance from obstacle. Warning level is divided into 3 step. (warning level rises progressively according to distance from obstacle)

DTC Description

This code reports an error in LIN line. The purpose is to verify the status of BCM, Sensor and Wire when error is detected at RPAS of Rear Center Left Sensor.
