When the ignition SW turned on, the current from the WIPER fuse flows to the front wiper and washer SW TERMINAL 17,
and the front wiper motor TERMINAL 2.
1. Low Position
When the front wiper SW is turned to LO position, the current flows from the front wiper and washer SW TERMINAL 17 to
TERMINAL 7 to the front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the front wiper motor at low
speed.
2. High Position
When the front wiper SW is turned to HI position, the current flows from the front wiper and washer SW TERMINAL 17 to
TERMINAL 8 to the front wiper motor TERMINAL 4 to TERMINAL 5 to GROUND, and operates the front wiper motor at high
speed.
3. INT Position
When the front wiper SW is turned to INT position, the relay operates and the current which is connected by the relay
function flows from the front wiper and washer SW TERMINAL 17 to TERMINAL 2 to GROUND, and operates the wipe.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the
intermittent time is controlled by a time control SW to change the charging time of the condenser.
4. Washer Interlocking Operation
When the front washer SW is pulled up, the current flows from the washer motor TERMINAL 2 to TERMINAL 3 to the front
wiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND, operates the washer motor and the window washer
emits a water spray. This causes the current to flow to the washer continuous operation circuit in the front wiper and washer
SW TERMINAL 11 to TERMINAL 7 to front wiper motor TERMINAL 1 to TERMINAL 5 to GROUND, and operates the wiper.
C19 Combination SW
17-Ground : Approx. 12 volts with ignition SW at ON or ST position
7-Ground : Approx. 12 volts with front wiper and washer SW at LO position
: Approx. 12 volts 1.6 to 10.7 seconds intermittently with the front wiper and washer SW at INT position
16-Ground : Approx. 12 volts with ignition SW on unless the front wiper motor at STOP position
8-Ground : Approx. 12 volts with front wiper and washer SW at HI position
2-Ground : Always continuity

GENERAL MAINTENANCE
1. GENERAL NOTICE

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance services after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item can cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the LEVEL lines on the see-through reservoir at normal tem-
perature (20°C (68°F)).
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(See page CO-14)
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL

Check the indicator.

When the indicator color is blue, the condition is satisfactory. A red color indicates that distilled water
must be added, and white indicates that charging is necessary.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see-through reservoir.
(See page BR-4)
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL

Check the level on the dipstick.

The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
Visually check the overflow plug and oil pan for fluid leaks or traces of fluid.
