PRECAUTION
1. EXPRESSIONS OF IGNITION SWITCH
(a) The type of ignition switch used on this model differs
according to the specifications of the vehicle. The expressions listed in the table below are used in this section.
Switch Type Ignition Switch (position) Engine Switch (condition)
Ignition switch off LOCK Off
Ignition switch on (IG) ON On (IG)
Ignition switch on (ACC) ACC On (ACC)
Engine start START Start
2. PRECAUTION OF WASHER NOZZLE ADJUSTMENT
(a) Do not clean or adjust the washer nozzle with a
safety pin, etc. because; (1) the washer nozzle tip is made of resin and could
be damaged.
(2) adjustment is not necessary because the
washer nozzle is a spray type. If it is necessary to change the nozzle angle, replace the washer nozzle with one that has a different nozzle angle. (See page WW-28)
(b) In case the washer nozzle is clogged with wax, etc.,
remove it and clean the nozzle hole with a soft resin brush, etc.

WIPER AND WASHER – WIPER AND WASHER SYSTEM
SYSTEM DESCRIPTION
1. WASHER LINKED OPERATION
(a) This system operates the front wipers at a low
speed immediately after a jet of washer fluid when the front washer switch is turned on for approximately 0.3 seconds or more. If the switch is turned off within approximately 1.5 seconds, the system stops the wipers when the switch is turned off. If the switch is turned on for approximately 1.5 seconds or more, the system stops the wipers approximately 2.2 seconds after the switch is turned off.
2. INTERMITTENT OPERATION
(a) The system operates the front wipers once in
approximately 1.6 to 10.7 seconds when the front wiper switch is turned to the INT position. The intermittent time can be adjusted between 1.6 and
10.7 seconds.
(b) If the wiper control switch is turned to the INT
position, current flows from the already charged capacitor C1 to Tr1 (transistor) through terminals INT1 and INT2 of the wiper control switch. When Tr1 turns on, current flows from terminal +S of the wiper control switch to terminal +1 of the wiper control switch, to terminal +1 of the wiper motor, to the wiper motor and finally to the ground, causing the wiper motor to operate. At the same time, current flows from capacitor C1 to terminal INT1 of the wiper control switch and then INT2. When the current flow from capacitor C1 ends, Tr1 turns off to stop the relay contact point and halt the wiper motor. When the relay contact point turns off, capacitor C1 begins to charge again and Tr1 remains off until charging has been completed. This period corresponds to the intermittent time. When capacitor C1 is fully charged, Tr1 turns on and then the relay contact point activates, causing the motor to operate. This cycle is the intermittent operation. The intermittent time can be adjusted by using the intermittent time adjust dial (variable resistor) to change the charge time of capacitor C1.

1. INSPECT WINDSHIELD WIPER MOTOR ASSEMBLY (for TMC Made)
(a) LO Operation Check
(1) Connect a positive (+) battery lead to terminal
B1-5 (+1) of the connector, and a negative (-) battery lead to terminal B1-4 (E), and check that the motor operates at low speed (LO).
(b) HI Operation Check
(1) Connect a positive (+) lead to terminal B1-3
(+2) of the connector , and a negative (-) battery lead to terminal B1-4 (E), and check that the motor operates at high speed (HI).
(c) Automatic Stop Operation Check
(1) Put matchmarks on the windshield wiper motor
assembly. The matchmarks will be used to confirm the return of the motor shaft to the park position.
