How To Proceed With Troubleshooting

NOTE:

DTCs for the CAN communication system are as follows: U0073, U0100, U0101, U0122, U0123, U0124, U0126, U0132, U0145, U1101, U0104, U0105, U0114, U0121, U0130, U0131, U0146, U1002, U1108, U1109, U1110.
Refer to troubleshooting of each system DTCs regarding the CAN communication system are not output.

CHECK AND CLEAR DTCS
CHECK FOR INSTALLED SYSTEMS (ECUS & SENSORS) THAT USE CAN COMMUNICATION
1. Check which of the following is used: intuitive parking assist (rear view monitor or back guide monitor), intuitive parking assist, dynamic laser cruise control and engine model.
CHECK CAN BUS LINE
1. Check CAN BUS LINE .
CHECK INTELLIGENT TESTER VIA CAN VIM
1. Select "BUS CHECK" (see DIAGNOSIS SYSTEM ).
  Standard:
  
  All ECUs and sensors connected to the CAN communication system are displayed.
  NOTE:
  - The systems (ECUs, sensors) that use CAN communication vary depending on the vehicle and option settings. Check which systems (ECUs, sensor) are installed on the vehicle (see DIAGNOSIS SYSTEM )
  - Non-installed ECUs or sensors are not displayed. Do not mistake them for being in the communication stop mode.
  - If 2 or more ECUs or sensors are not displayed on the intelligent tester via the CAN VIM, perform troubleshooting for communication stop mode for each undisplayed ECU or sensor. (Open in on side of CAN sub bus line.)
NO: COMMUNICATION STOP MOOD TABLE

YES: Go to next step
DTC COMBINATION TABLE
1. Confirm trouble according to the combination of output DTCs regarding the CAN communication system.
  HINT:
  
  Previous CAN communication system DTCs may be the cause if CAN communication system DTCs are output and all ECUs and sensors connected to the CAN communication system are displayed on the intelligent testers "BUS CHECK" screen via the CAN VIM.
