PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000003533860
Two different maintenance schedules are provided, 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 or time intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000003533861
After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. [ ]: At the mileage intervals only
Schedule 1Follow Periodic Maintenance Schedule 1 if your driving habits frequently includes
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 re-
maining 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 or using a car-top carrier.Emission Control Sys-

POWER SUPPLY ROUTING CIRCUIT
Fuse
INFOID:0000000003533832
• If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
• Use fuse of specified rating. Never use fuse of more than specified
rating.
• Do not partially install fuse; always insert it into fuse holder prop-
erly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkINFOID:0000000003533833
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:
• If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.
• Never wrap outside of fusible link with vinyl tape.
• Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)INFOID:0000000003533834
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
• Power windows
• Power door locks
• Remote keyless entry system
• Power sunroof
• Rear window wiper

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
NOTE:
• Perform monitoring of IPDM E/R data with the ignition switch ON. When the ignition switch is in ACC posi-
tion, display may not be correct.

ACTIVE TEST
Auto Active TestINFOID:0000000003533839
DESCRIPTION
• In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
- Rear window defogger
- Front wipers
- Tail and parking lamps
- Front fog lamps
- Headlamps (Hi, Lo)
- A/C compressor (magnet clutch)
- Cooling fan
OPERATION PROCEDURE
1. Close hood and front door RH, and lift wiper arms away from windshield (to prevent glass damage by
wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, press front door switch LH 10 times. Then turn ignition
switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.

CAUTION:
Be sure to perform BL-25, "
Door Switch Check" when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
• When auto active test mode is actuated, the following seven steps are repeated three times.
Concept of Auto Active Test
• IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communi-
cation line. Therefore, when auto active test mode is activated successfully, CAN communication between
IPDM E/R and BCM is normal.
• If any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
