ICC SYSTEM CANNOT BE SET (MAIN SWITCH TURNS ON/OFF)
ICC SYSTEM CANNOT BE SET (MAIN SWITCH TURNS ON/OFF)
Diagnosis ProcedureINFOID:0000000005146010
The ICC cannot be set in the following cases.
• When the vehicle speed is not in range of approx . 40 km/h (25 MPH) to 144 km/h (89 MPH).
• When the selector lever is in "N".
• While the brake is in operation.
• When the windshield wipers are operating.
1.CHECK CAUSE OF AUTOMATIC CANCELLATION
1. With “CAUSE OF AUTO-CANCEL” in "WORK SUPPOR T", check if any cause of cancellation exists.
Is there a cause of cancellation stored?
YES >> • Cancel with appropriate cause. • For causes A, B, or C, go to specified diagnosis.A: “OPE SW VOLT CIRC” : Refer to CCS-30, "
DTC 46 OPERATION SW CIRC".
B: “VHCL SPD UNMATCH” : Refer to CCS-26, "
DTC 41 VHCL SPEED SE CIRC".
C: “IGN LOW VOLT” : Refer to CCS-25, "
DTC 31 POWER SUPPLY CIR1, DTC 34
POWER SUPPLY CIR2".
NO >> GO TO 2
2.PERFORM SELF-DIAGNOSIS
1. Perform -self-diagnosis to check for malfunctioning items.
Does the ICC have any DTC’s stored?
YES >> Repair or replace as necessary, erase DTC. Perform ICC system running test. Refer to CCS-8,
"ACTION TEST : ICC System Running Test".
NO >> GO TO 3
3.CHECK SWITCHES AND VE HICLE SPEED SIGNAL
1. With "DATA MONITOR", check that the following switches and vehicle speed signal operate normally. A: VHCL SPEED SE B: NP RANGE SW
C: BRAKE SW D: SET/COAST SW
Do the monitor items display properly?
YES >> Replace ICC unit and erase DTC. Refer to CCS-71, "ICC Unit". Perform ICC system running test.
Refer to CCS-8, "
ACTION TEST : ICC System Running Test".
NO >> • A: Refer to CCS-26, "
DTC 41 VHCL SPEED SE CIRC".
• B: Refer to CCS-62, "
Diagnosis Procedure".
• C: Refer to CCS-28, "
DTC 45 BRAKE SW/STOP L SW".
• D: Refer to CCS-30, "
DTC 46 OPERATION SW CIRC".

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the follo wing systems to check their operation.
• Oil pressure low/coolant pressure high warning indicator
• Oil pressure gauge
• Rear window defogger
• Front wipers
• Tail, license and parking lamps
• Front fog lamps
• Headlamps (Hi, Lo)
• A/C compressor (magnetic clutch)
• Cooling fan
Operation Procedure
1. Close the hood and front door RH, and lift the wiper a rms from the windshield (to prevent windshield dam-
age due to wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to DLK-71, "
Descrip-
tion".
• Do not start the engine.

GENERAL MAINTENANCE
General MaintenanceINFOID:0000000005145933
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owner can perform these
checks and inspections or have thei r INFINITI dealers perform them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed fr om time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.
Item Reference page
Tires Check the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear. WT-47, "
Inspection"
Wheel lug nuts
When checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary. WT-49, "Rotation"
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. GW-11, "Removal and
Installation"
Tire rotation
Tires should be rotated every 12,000 km (7,500 miles). WT-49, "Rotation"
Tire Pressure Monitor-
ing System (TPMS)
transmitter componentsReplace the TPMS transmitter grommet seat, valve core and cap when the tires
are replaced due to wear or age.
WT-50, "Transmitter
(Pressure Sensor)"
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel bal-
ancing may be needed. WT-48, "Balancing
Wheels", FSU-6, "Front
Wheel Alignment"
Windshield wiper
blades
Check for cracks or wear if they do not wipe properly.
—
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the back
door. Also make sure that all latches lock securely. Lubricate if necessary. Make
sure that the secondary latch keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently. MA-38, "

Lamps
Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head
lamp aim. Clean the head lamps on a regular basis. EXL-145, "HEADLAMP :

Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner. —
Steering wheel Check that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.
Free play: less than 35mm (1.38 in) ST-15, "

Seats
Check seat position controls such as seat adjusters, seat back recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restraints move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seat backs. —
