DescriptionINFOID:0000000006223651
The switch does not turn ON
When the DCA system setting is ON, the DCA system switch indicator does not illuminate even if the
dynamic driver assistance switch is depressed.
The switch does not turn OFF
The DCA system switch indicator does not turn OFF even if the dynamic driver assistance switch is pressed
when the DCA system switch indicator illuminates.
NOTE:
The system cannot be operated when setting conv entional (fixed speed) cruise control mode.
Diagnosis ProcedureINFOID:0000000006223652
1.CHECK DCA SYSTEM SETTING
1. Start the engine.
2. After starting the engine wait for 5 seconds or more.
3. Check that DCA system setti ng on the navigation screen is ON.
Is DCA system setting ON?
YES >> GO TO 2.
NO >> Enable the DCA system setting.
2.DYNAMIC DRIVER ASSISTA NCE SWITCH INSPECTION
1. Start the engine.
2. Check that “DYNA ASIST SW” operates normally in “DATA MONITOR” of “ICC/ADAS” with CONSULT-III.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 5.
3.CHECK DCA SYSTEM SWITCH INDICATOR CIRCUIT
1. Start the engine.
2. Select the active test item “DCA IN DICATOR” of “ICC/ADAS” with CONSULT-III.
3. Check if the DCA system switch indicator illuminates when the test item is operated.
Is the inspection result normal?
YES >> GO TO 6.
NO >> GO TO 4.
4.PERFORM THE SELF-DIAGNOSIS OF COMBINATION METER
1. Perform “All DTC Reading” with CONSULT-III.
2. Check if the DTC is detected in self-d iagnosis results of “METER/M&A”. Refer to MWI-43, "
DTC Index".
Is the inspection result normal?
YES >> GO TO 7.
NO >> GO TO 6.
5.CHECK STEERING SWITCH CIRCUIT
Check the steering switch circuit. Refer to DAS-138, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 6.
NO >> GO TO 7.
6.PERFORM THE SELF-DIAGNOSIS
1. Perform “All DTC Reading” with CONSULT-III.
2. Check if the DTC is detected in self-diagnosis results of “ICC/ADAS”. Refer to DAS-100, "

The FCW system will function when own vehicle is dr iven at speeds of approximately 15 km/h (10 MPH) and
above.
NOTE:
The FCW system shares the di agnosis function with ICC system.
FUNCTION DESCRIPTION
The distance from the vehicle ahead and a relative speed are calculated by using the ICC sensor and an ICC
sensor signal is transmitted to t he ADAS control unit via ITS communi cation. When judging the necessity of
warning according to the received vehicle ahead detection signal, the ADAS control unit transmits a buzzer
output signal and meter display signal to the combination meter via CAN communication.
FCW Operating Condition
Warning systems ON indicator: ON
Vehicle speed: Approximately 15 km/h (10 MPH) and above.
Fail-safe Indication
FCW INITIAL STATE CHANGE
CAUTION:
Never change FCW initial state “ON” ⇒ “OFF” without the con sent of the customer.
FCW initial state can be changed.
FCW initial ON* - FCW function is automatically turned ON, when the ignition switch OFF ⇒ ON.
FCW initial OFF - FCW function is still OFF when the ignition switch OFF ⇒ ON.
*: Factory setting
How to change FCW/LDW/BSW initial state1. Turn ignition switch ON.
2. Warning systems switch is OFF.
3. Push and hold warning systems switch for more than 4 seconds.
4. Buzzer sounds and blinking of the warning systems ON indicator informs that the FCW/LDW/BSW initial
state change is completed.
Fail-safe (ADAS Control Unit)INFOID:0000000006223674
If a malfunction occurs in each s ystem, ADAS control unit cancels eac h control, sounds a beep, and turns ON
the warning lamp or indicator lamp.
Vehicle condition Indication on the combination meter
When the FCW system malfunctions
When the sensor window is dirty
When driving into a strong light (i.e. sunlight)
NOTE:
Check that the IBA system is not OFF. The indicator lamp is shared
with IBA system.
