provided by the sensors in order to optimally distribute drive torque
in accordance with driving conditions.
ECMOutputs signals such as the shift position signal, throttle position
signal, and crankshaft position signal to the 4WD ECU.
Skid Control ECUOutputs signals such as the vehicle speed signal and deceleration
signal to the 4WD ECU.
Electric Control CouplingDistributes drive torque in accordance with the amperage applied
by the 4WD ECU.

GENERAL MAINTENANCE
(2006/01- )
1. GENERAL NOTES
• Maintenance requirements vary depending on the
country.
• Check the maintenance schedule in the owner's
manual supplement.
• Following the maintenance schedule is mandatory.
• Determine the appropriate time to service the vehicle
using either miles driven or time elapsed, whichever
reaches the specification first.
• Maintain similar intervals between periodic
maintenance, unless otherwise noted.
• Failing to check each vehicle part could lead to poor
engine performance and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
(a) Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
(a) Check that the coolant level is between the "FULL"
and "LOW" lines on the see-through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not
blocked by leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose
connections.
5. BATTERY ELECTROLYTE LEVEL
(a) Check that the electrolyte level of all the battery
cells is between the upper and lower level lines on
the case.
HINT:
If the electrolyte level is difficult to see, lightly shake
the vehicle.
6. BRAKE FLUID LEVEL
(a) Check that the brake fluid levels are near the upper
level lines on the see-through reservoirs.
7. ENGINE DRIVE BELT
(a) Check the drive belt for fraying, cracks, wear or
oiliness.
8. ENGINE OIL LEVEL
(a) Check the level on the dipstick with the engine
stopped.
9. AUTOMATIC TRANSAXLE FLUID LEVEL
10. EXHAUST SYSTEM
(a) Check for unusual exhaust sounds or abnormal
exhaust fumes. Inspect the cause and repair it.
