CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication
line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H, CAN-L) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-28, "
CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
ITS communication is a multiplex communication system . This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with 2 communication lines.
ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

NOTE:
If “U1000” is detected, first diagnose the CAN communication system.
ADAS CONTROL UNIT : Diagnosis ProcedureINFOID:0000000006228147
1.PERFORM THE SELF-DIAGNOSIS
1. Turn the ignition switch ON.
2. Turn the DCA system ON, and then wait for 30 seconds or more.
3. Perform “All DTC Reading” with CONSULT-III.
4. Check if the “U1000” is detected as the current ma lfunction in “Self Diagnostic Result” of “ICC/ADAS”.
Is
“U1000” detected as the current malfunction?
YES >> Refer to LAN-18, "Trouble Diagnosis Flow Chart".
NO >> Refer to GI-40, "
Intermittent Incident".
