 Result: Symptom
NOTE:
 Check normal units as well as error symptoms.
- Example: Circuit between ECM and the combination meter is judged normal if the customer indicates tachometer functions normally.
 When a CAN communication system error is present, mult iple control units may malfunction or go into fail-
safe mode.
 Indication of the combination meter is important to det ect the root cause because it is the most obvious to
the customer, and it performs CA N communication with many units.
INSPECTION OF VEHICLE CONDITION
 Check whether or not “U1000” or “U1001” is indi cated on “SELF-DIAG RESULTS” by CONSULT-III.
NOTE:
Root cause cannot be detected using the procedure in this section if “U1000” or “U1001” is not indicated.
 Check whether the symptom is reproduced or not.
NOTE:
 Do not turn the ignition switch OFF or disconnect the battery cable while reproducing the error. The error may temporarily correct itself, making it difficult to determine the root cause.
 The procedures for present errors differ from the procedures for past errors. Refer to "DETECT THE
ROOT CAUSE".
CHECK OF CAN SYSTEM TYPE (HOW TO US E CAN SYSTEM TYPE SPECIFICATION CHART)
Determine CAN system type based on vehicle equipm ent. Then choose the correct diagnosis sheet.
NOTE:
There are two styles for CAN system type specificat ion charts. Depending on the number of available system
types, either style A or style B may be used.

PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000001328894
Two different maintenance schedules are provi ded, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage/time intervals.
Schedule 1INFOID:0000000001328895
EMISSION CONTROL SYSTEM MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or r eplace if necessary. [ ]: At the mileage intervals only
Schedule 1Follow Periodic Maintenance Schedule 1 if the driving habits frequently include
one or more of the following driving conditions:
 Repeated short trips of less than 5 miles (8 km).
 Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.
 Operating in hot weather in stop-and-go “rush hour” traffic.
 Extensive idling and/or low speed driving for long distances, such as police, taxi or door-to-door delivery use.
 Driving in dusty conditions.
 Driving on rough, muddy, or salt spread roads.
 Towing a trailer, using a camper or a car-top carrier. Emission Control Sys-

PERIODIC MAINTENANCE
NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.
