ICC SENSOR INTEGRATED UNIT : Description
INFOID:0000000005501969
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 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-30, "CAN Communication 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 ICC sensor integrated unit, brake booster control unit,
and accelerator pedal actuator with 2 communication lines.
• ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

NOTE:
If “U1000” is detected, first diagnose the CAN communication system.
ICC SENSOR INTEGRATED UNIT : Diagnosis Procedure
INFOID:0000000005501971
1.
PERFORM THE SELF-DIAGNOSIS
1.
Turn the ignition switch ON.
2.
Turn the DCA system ON, and wait for 30 seconds or more.
3.
Perform “All DTC Reading” with CONSULT-III.
4.
Check if the “U1000” is detected as the current malfunction in self-diagnosis results of “ICC”.
Is “U1000” detected as the current malfunction?
YES
>> Refer to
LAN-20, "Trouble Diagnosis Flow Chart"
NO
>> Refer to
GI-36, "Intermittent Incident"
.
