DescriptionINFOID:0000000009464922
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-32, "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 di agnose the CAN communication system.
Diagnosis ProcedureINFOID:0000000009464924
1.PERFORM THE SELF-DIAGNOSIS
1. Turn the ignition switch ON.
2. Turn the MAIN switch of ITS system ON, and then wait for 30 seconds or more.
3. Perform “All DTC Reading” with CONSULT.
4. Check if the “U1000” is detected as the current malfunction in “Self Diagnostic Result” of “AVM”.
Is
“U1000” detected as the current malfunction?
YES >> Refer to DAS-266, "Description".
NO >> Refer to GI-43, "Intermittent Incident"
.

After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.
