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.
Refer to troubleshooting of each system if DTCs regarding the CAN communication system are not output.

CHECK AND CLEAR DTCs
1. NEXT : Go to next step.
CHECK FOR INSTALLED SYSTEMS (ECUS & SENSORS) THAT ADOPT CAN COMMUNICATION)
1. Check which of the following is adopted: dynamic radar/laser cruise control and vehicle stability control.
1. NEXT : Go to next step.
CHECK CAN BUS LINE
1. NEXT : Go to next step.
CHECK HAND-HELD TESTER VIA CAN VIM
1. Select "BUS CHECK" (see CHECK CAN BUS LINE )
  Standard: All ECUs and sensors connected to the CAN communication system are displayed.
  NOTE:
  - The systems (ECUs, sensors) that adopt CAN communication vary depending on the vehicle and option settings. Check which systems (ECUs, sensors) are installed on the vehicle (see PROBLEM SYMPTOMS TABLE ).
  - Non-installed ECUs or sensors are not displayed. Do not mistake them for being in the communication stop mode.
1. NO : COMMUNICATION STOP MODE TABLE (SEE PROBLEM SYMPTOMS TABLE )
2. YES : Go o next step.
DTC COMBINATION TABLE (SEE PROBLEM SYMPTOMS 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 hand-held tester's "BUS CHECK" screen via the CAN VIM.
