DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Start the engine.
2. Turn the LDP system ON.
3. Perform “All DTC Readi ng” with CONSULT-III.
4. Check if the “U0401” is detected as the current ma lfunction in “Self Diagnostic Result” of “ICC/ADAS”.
Is
“U0401” detected as the current malfunction?
YES >> Refer to DAS-369, "Diagnosis Procedure".
NO >> Refer to GI-40, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000006228205
1.CHECK SELF-DIAGNOSIS RESULTS
Check if “U1000” is detected other than “U0401” in “Self Diagnostic Result” of “ICC/ADAS”.
Is
“U1000” detected?
YES >> Perform the CAN communicati on system inspection. Repair or replace the malfunctioning parts.
Refer to DAS-374, "
ADAS CONTROL UNIT : DTC Logic".
NO >> GO TO 2.
2.CHECK ECM SELF-DIAGNOSIS RESULTS
Check if any DTC is detected in “S elf Diagnostic Result” of “ENGINE”.
Is any DTC detected?
YES >> Perform diagnosis on the detected DTC and repair or replace the malfunctioning parts. Refer to
EC-98, "
DTC Index".
NO >> Replace the ADAS control unit. Refer to DAS-63, "
Removal and Installation".

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.

NP RANGE SW
[On/Off] × Indicates shift position signal read from ADAS control unit through CAN commu-
nication (TCM transmits shift position signal through CAN communication)
PKB SW
[On/Off] × Parking brake switch status [On/Off] judged from the parking brake switch signal
that ADAS control unit readout via CAN communication is displayed (Combination
meter transmits the parking brake switch signal via CAN communication)
PWR SUP MONI
[V] ××
Indicates IGN voltage input by ADAS control unit
VHCL SPD AT
[km/h] or [mph] × Indicates vehicle speed calculated from A/T vehicle speed sensor read from
ADAS control unit through CAN communication (TCM transmits A/T vehicle speed
sensor signal through CAN communication)
THRTL OPENING
[%] ×× Indicates throttle position read from ADAS control unit through CAN communica-
tion (ECM transmits accelerator pedal position signal through CAN communica-
tion).
GEAR
[1, 2, 3, 4, 5, 6, 7] × Indicates A/T gear position read from ADAS control unit through CAN communi-
cation (TCM transmits current gear position signal through CAN communication)

control mode]
SET DISP IND
[On/Off] ×
Indicates [On/Off] status of SET switch indicator output
DISTANCE
[m] ×
Indicates the distance from the vehicle ahead
RELATIVE SPD
[m/s] ×
Indicates the relative speed of the vehicle ahead
DYNA ASIST SW
[On/Off] ×× ×
Indicates [On/Off] status as judged from ICC steering switch signal (ECM trans-
mits ICC steering switch signal through CAN communication)
DCA ON IND
[On/Off] ×
The status [ON/OFF] of DCA system switch indicator output is displayed
DCA VHL AHED
[On/Off] × The status [ON/OFF] of vehicle ahead detection indicator output in DCA system
is displayed
IBA SW
[On/Off] ××
Indicates [On/Off] status of IBA OFF switch
FCW SYSTEM ON
[On/Off] ××
Indicates [On/Off] status of FCW system
APA TEMP
[ ° C] × Accelerator pedal actuator integrated motor temperature that the ADAS control
unit readout via ITS communication is displayed (Accelerator pedal actuator trans-
mits the integrated motor temperature via ITS communication)
APA PWR
[V] × Accelerator pedal actuator power supply voltage that the ADAS control unit read-
out via ITS communication is displayed (Accelerator pedal actuator transmits the
power supply voltage via ITS communication)
LDW SYSTEM ON
[On/Off] ×
Indicates [On/Off] status of LDW system
