ACTION TEST
DescriptionINFOID:0000000006224297
Always perform the ICC system action test to check that the ICC system operates normally after replacing the
ICC sensor or repairing any ICC system malfunction.
CAUTION:
 Always drive safely when pe rforming the action test.
 Turn the DCA system to OFF when performing the action test.
Work Procedure (Vehicle-To-Vehicle Distance Control Mode)INFOID:0000000006224298
NOTE:
 When there is no vehicle ahead, drive at the set speed steadily.
 When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.
 The running speed can be set between 32 km/h (20 MPH) and 144 km/h (90 MPH).
CAUTION:
Never set the cruise speed exceeding the posted speed limit.
1.CHECK FOR MAIN SWITCH
1. Start the engine.
2. Press the MAIN switch (1) (less than 1.5 seconds).
3. Check the ICC system display on the information displa y to check that the vehicle-to-vehicle distance con-
trol mode is ready for activation.
4. Press the MAIN switch, and check that the ICC syst em display on the information display turns OFF when
the ICC system is deactivated.
5. Check that the ICC system displa y on the information display turns OFF after starting the engine again.
>> GO TO 2.
2.CHECK FOR DISTANCE SWITCH
1. Start the engine.
2. Press the MAIN switch (less than 1.5 seconds).
3. Press the DISTANCE switch.

ACTION TEST
4. Check that the set distance indicator changes display in order of: (Long)
→(Middle) →(Short).
NOTE:
When the MAIN switch is turned ON, initial setting set to (Long). >> GO TO 3.
3.CHECK FOR RESUME/ACCELERATE, SE T/COAST, AND CANCEL SWITCHES
1. Check that RESUME/ACCELE RATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check that switches come up as hand is released from the switches.
>> GO TO 4.
4.SET CHECKING (1)
1. Start the engine.
2. Press the MAIN switch (less than 1.5 seconds) and tu rn the vehicle-to-vehicle distance control mode ON.
3. Drive the vehicle at 32 km/h (20 MPH) or more.
4. Push down the SET/COAST switch.
5. Check that the desired speed is set and vehicle-to -vehicle distance control mode control starts when
releasing SET/COAST switch.
NOTE:
The set vehicle speed is indicated on the set vehicle s peed indicator in the ICC system display on the informa-
tion display.
>> GO TO 5.
5.CHECK FOR INCREASE OF CRUISING SPEED (1)
1. Set the vehicle-to-vehicle distance control mode at desired speed.
2. Check that the set speed increases by 1 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.
NOTE:
The maximum set speed of the vehicle-to-vehicl e distance control mode is 144 km/h (90 MPH).
CAUTION:
Never set the cruise speed exceed ing the posted speed limit.
>> GO TO 6.
6.CHECK FOR DECREASE OF CRUISING SPEED (1)
1. Set the vehicle-to-vehicle distance control mode at desired speed.
2. Check that the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:
 The minimum set speed is approximately 32 km/h (20 MPH).

 Cancel the control automatically when the vehicle speed is less than approximately 24 km/h (15 MPH) and
when the system does not detect any vehicle ahead.
>> GO TO 7.
7.SET CHECKING (2)
1. Stop the vehicle.
2. Drive the vehicle at less than approximately 32 km/h (20 MPH).
3. Push down the SET/COAST switch w hen the system detects a vehicle ahead.
4. Check that the vehicle-to-vehicle distance control mode is performed so that the vehicle maintains a
proper distance according to the vehicle speed [maximum: approximately 32 km/h (20 MPH)] when
releasing SET/COAST switch.
NOTE:
 The vehicle-to-vehicle distance control mode cannot be set when the vehicle speed is less than 32 km/h (20
MPH) and when a vehicle ahead is not detected.
 Cancel the control automatically w hen the vehicle speed is 24 km/h (15 MP H) or less during the control and
when the system does not detect any vehicle ahead.
 The set vehicle speed indicator in the ICC system display on the information display is set to 32 km/h (20 MPH).
>> GO TO 8.
8.CHECK FOR INCREASE OF CRUISING SPEED (2)
1. Set the vehicle-to-vehicle distance control mode when the vehicle speed is less than approximately 32
km/h (20 MPH) and when a vehicle ahead is detected.
2. Check that the set speed increases by 1 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.
NOTE:
The maximum set speed of the vehicle-to-vehicl e distance control mode is 144 km/h (90 MPH).
CAUTION:
Never set the cruise speed exceed ing the posted speed limit.
>> GO TO 9.
9.CHECK FOR DECREASE OF CRUISING SPEED INSPECTION (2)
1. Set the vehicle-to-vehicle distance control mode when the vehicle speed is less than approximately 32
km/h (20 MPH) and when a vehicle ahead is detected.
2. Set the set vehicle speed to the desired vehicle speed according to “check for increase of cruising speed”.
3. Check that the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:
 The minimum the set speed is approximately 32 km/h (20 MPH).
 If the vehicle ahead comes to a stop, the vehicle decelerat es to a standstill within the limitations of the sys-
tem. The system will cancel once it j udges a standstill with a warning chime.
CAUTION:
The creep occurs because the stop status is not maintained.
>> GO TO 10.
10.CHECK FOR CANCELLATION OF VEHICLE-T O-VEHICLE DISTANCE CONTROL MODE
Check that the vehicle-to-vehicle distance control m ode is canceled when performing the following operations.
 When the brake pedal is depressed after vehicle-to-vehi cle distance control mode is set and the vehicle is
driven.
 When the selector lever is in the “N” position after vehicle-to-vehicle distance control mode is set and the
vehicle is driven.
 When the MAIN switch is turned OFF after vehicle-to -vehicle distance control mode is set and the vehicle is
driven.
 When the CANCEL switch is pressed after vehicle-to-v ehicle distance control mode is set and the vehicle is
driven.
>> GO TO 11.
