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. IPM 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 RPAS UNIT, Sensor and Wire when error is detected at RPAS of left side sensor.

This is DTC which is related with communication error between IPM and other units.

Body CAN communication Control Units: IPM (Inter Panel Module), CLU (Cluster), SMK (Smart Key), HU (Head Unit).

*1 CAN (Controller Area Network): CAN is serial bus communication type which links not only communication system but also control units each other.

*2 LIN (Local Interconnect Network): LIN is serial communication type which is used in electrical control system. (This is less expensive.)

Scheme 21

Scheme 21: General Description

This is DTC which is related with communication error between IPM and other units.

( Control Units: IPM (Inter Panel Module), CLU (Cluster), SMK (Smart Key), HU (Head Unit).

Case 1: After short between CAN Low Line and High Line, short to ground together.

Case 2: After short between CAN Low Line and High Line, short to power together.

This code is occurred when It is not possible to transmit data by CAN Line in those way of Software and Hardware. But, It is possible to receive data by CAN Line.

This code reports BUS OFF status when data transmit error count number is over 255. The purpose is to verify the status of CAN controller and CAN communication line when error is detected.

According to operation condition, some of module which are connected to CAN line may not detect B1603.

Also, B1602 coincides with B1603 at all times.

CAUTIONDifference between CAN ERROR and CAN BUS ERROR CAN Error: MIL On, CAN Bus Error: No MIL
