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)
This code reports an error in LIN line. The purpose is to verify the status of RPAS UNIT, Sensor and Wire when error is detected at RPAS of Rear Center Left Sensor.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Signal output of Rear Center Left Sensor and LIN line checking | 1. TX line of RPAS-CLH(Rear Center Left Sensor) open or poor connection 2. Ground line of RPAS-CLH(Rear Center Left Sensor) open or poor connection 3. Power line of RPAS-CLH(Rear Center Left Sensor) open or poor connection 4. Replace a sensor after checking a wire of RPAS-CLH(Rear Center Left Sensor) |
Enable Conditions |
•
IG KEY ON, Shift lever R | |
Threshold Value |
•
Sensor fault
•
LIN communnication fault
•
Poor connection
•
LIN line open | |
Diagnostic Time |
•
Immediately (1 check lasts 0.3 sec after IG KEY ON) | |
DTC Erasing Time |
•
DTC is erased immediately after trouble fixed |
