BCM(PAS) is a parking assistant system. It has a supersonic sensor which radiates supersonic to front and rear side of the vehicle to detect supersonic reflected from an obstacle. It calculates distances between vehicle and obstacle if it detects reflected supersonic. 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 BCM(PAS), Sensor and Wire when error is detected at PAS of Front Right Side Sensor.
