ACTION TEST
Revision: 2007 April2007 M35/M45
ACTION TESTPFP:00000
ICC System Running TestNKS004CL
NOTE:
ICC system can set VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE and CONVENTIONAL (FIXED
SPEED) CRUISE CONTROL MODE when selector lever is in “D” and “M” position.
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
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.
Set Checking
1. Press the MAIN switch for less than 1.5 seconds.
2. Drive the vehicle between 40 km/h (25 MPH) and 144 km/h (90 MPH).
3. Push down the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
NOTE:
The set vehicle speed is displayed on the dot matrix LCD in the combination meter.
Check For Increase Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if 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-vehicle distance control mode is 144 km/h (90 MPH).
Check For Decrease Of Cruising Speed
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:

Vehicle-to-vehicle distance control mode is automatically cancelled when the driving speed lowers to 32
km/h (20 MPH) due to the deceleration of the vehicle ahead.

The minimum set speed of the vehicle-to-vehicle distance control mode is 40 km/h (25 MPH).
Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Condi-
tion) In The Following Cases:
1. When the brake pedal is depressed after the system is turned ON.
2. When the selector lever is shifted to the “N” (Neutral) position.
3. When the MAIN switch is turned OFF.
4. When CANCEL switch is operated.
Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode Before
Cancellation
1. Cancel the system by depressing the brake pedal. Then, check if the speed before cancellation is
restored when pushing up RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N”. Then, check if the speed set before the cancella-
tion is restored when RESUME/ACCELERATE switch is pushed up.
3. Check if the speed previously set is restored when RESUME/ACCELERATE switch is operated with driv-
ing 40 km/h (25 MPH), after canceling vehicle-to-vehicle distance control mode by operating the CANCEL
switch.

Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. Vehicle-to-vehicle distance control mode is displayed in combi-
nation meter and “CRUISE” is illuminated when MAIN switch is
pressed “ON” for less than 1.5 seconds and ready for operation.
The illumination goes off when MAIN switch is turned to OFF.
3. “CRUISE” illumination and dot matrix LCD go off when the igni-
tion switch is turned to OFF while MAIN switch is ON (“CRUISE”
illumination is ON and vehicle-to-vehicle distance control mode
is ready for operation).
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.
Check For Distance Switch
1. Start engine.
2. Press the MAIN switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(Long)→(Middle)→(Short).
NOTE:
The set distance indicator shows (Long) immediately after the engine starts.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Set Checking
1. Press the MAIN switch for more than 1.5 seconds.
2. Drive the vehicle between 40 km/h (25 MPH) and 144 km/h (90 MPH).
3. Push down the SET/COAST switch.
4. Confirm that the desired speed is set as hand is released from the SET/COAST switch.
NOTE:
The set vehicle speed is not displayed on the dot matrix LCD in the combination meter.

Check For Increase Of Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed increases by 1.6 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.
NOTE:

If the RESUME/ACCELERATE switch is kept pushing up during cruise control driving, the vehicle speed
increases until the switch is released.

The maximum set speed is 144 km/h (90 MPH).
Check For Decrease Of Cruising Speed
1. Set the conventional (fixed speed) cruise control mode at desired speed.
2. Check if the set speed decreases by 1.6 km/h (1 MPH) as SET/COAST switch is pushed down.
NOTE:

Conventional (fixed speed) cruise control mode is automatically cancelled when the driving speed lowers
to 32 km/h (20 MPH).

The lowest set speed is 40 km/h (25 MPH).
Check For Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal Driving
Condition) In The Following Cases:
Refer to ACS-12, "Check For Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving Con-
dition) In The Following Cases:" .
Check For Restoring Speed That Is Set By Conventional (Fixed Speed) Cruise Control Mode
Before ICC Cancellation
Refer to ACS-12, "Check For Restoring Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation" .
Check For MAIN Switch
1. Start engine. Then, check if the following operations are per-
formed correctly.
2. “CRUISE” lamp illuminates and dot matrix LCD goes off when
MAIN switch is pressed “ON” for more than 1.5 seconds, and
then ready for operation. The illumination goes off when MAIN
switch is turned to OFF.
3. “CRUISE” illumination go off when the ignition switch is turned to
OFF while MAIN switch is ON.
Check For RESUME/ACCELERATE, SET/COAST, CANCEL Switches
1. Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.
2. Check if switches come up as hand is released from the switches.

LASER BEAM AIMING ADJUSTMENT
Revision: 2007 April2007 M35/M45
Aiming AdjustmentNKS004CQ
CAUTION:

Complete all necessary work for laser beam adjustment until the adjustment completes as shown
in the procedure. If the procedure does not complete, the ICC system is inoperable.

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect CONSULT-II and CONSULT-II CONVERTER, and then
touch “ICC” on “SELECT SYSTEM” screen.
If “ICC” is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
2. Touch “WORK SUPPORT”.
3. Touch “LASER BEAM ADJUST”.
4. Touch “START”.
CAUTION:
If the adjustment screen does not appear on the CONSULT-
II screen in 10 seconds. After touching “LASER BEAM
ADJUST” screen, the following causes may be considered:

Target is not set accurately.

There is not enough space beside the target.

The range of laser beam aiming exceeds for improper
installation position.
–Deformation of vehicle body.
–Deformation of unit.
–Deformation of bracket.

The area is not suitable for the adjustment work.

ICC sensor integrated unit is not clean.
