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 communicati on 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 high 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 syste m. This enables the system to transmit and receive
large quantities of data at high speed by connec ting control units with 2 communication lines.
ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.

1.PERFORM THE SELF-DIAGNOSIS
1. Start the engine.
2. Turn the BSW system ON, and then wait for 2 seconds or more.
3. Perform “All DTC Readi ng” with CONSULT-III.
4. Check if the “U1000” is detected as the current malfunction in “Self Diagnostic Result” of “SIDE RADAR
LEFT”.
Is
“U1000” detected as the current malfunction?
YES >> Refer to LAN-18, "Trouble Diagnosis Flow Chart".
NO >> Refer to GI-40, "
