REMOVAL AND INSTALLATION
For vehicle without air bag system, refer to Section 3C COMBINA-
TION SWITCH, and for vehicle with air bag system, refer to Section
3C1 CONTACT COIL AND COMBINATION SWITCH ASSEMBLY.
Wiper Motor
1) As illustrated, use a 12 V battery to connect its (+) terminal to ter-
minal ªAº, and its (±) terminal to Black lead wire (2) (Type A, B)
or terminal ªEº (Type C).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm, it
is proper. For high speed check, connect battery (+) terminal to
terminal ªBº, and its (±) terminal to Black lead wire (2) (Type A,
B) or terminal ªEº (Type C). If motor rotates at a high revolution
speed of 67 to 83 rpm, it is proper.

2) Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal ªAº of wiper mo-
tor (1) and (±) terminal to Black lead wire (2) (Type A, B) or
terminal ªEº (Type C), and let the motor turn.
b) Disconnect terminal ªAº from battery, and let the motor stop.
c) Connect terminal ªAº and ªDº with a jumper wire (3), and con-
nect terminal ªCº to battery (+) terminal. Observe the motor
turns once again then stops at a given position.
d) Repeat a) thru c) several times and inspect if the motor stops
at the given position every time.
Washer Pump
Connect battery (+) and (±) terminals to pump (+) and (±) terminals
respectively to check pumping rate.
Check for both front (3) and rear (2) (if equipped) washer pump.
Pumping Rate:
Front and Rear (if equipped) more than 1.0 l / min.
(2.1 US pt. / min.,
1.76 lmp pt. / min.).

Intermittent Wiper Relay Circuit
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Turn the intermittent time control switch to FAST position.
5) Connect battery positive terminal to terminal ªB3º and battery
negative terminal to terminal ªEº.
6) Connect voltmeter positive lead to terminal ª+1º and negative
lead to terminal ªEº.
Check that the voltmeter indicates the battery voltage (10 ±
14 V).
7) Connect terminal ªAsº and terminal ªB3º by a jumper wire. Then
move jumper wire end connected to terminal ªB3º to terminal ªEº.
Observe the voltmeter voltage drops to 0 V right after connecting
the jumper wire from terminal ªB3º to ªEº. Then the voltage rises
to battery voltage (10 ± 14 V) within the time shown in the table
below.

Wiper Motor
1) TESTING WIPER MOTOR
As shown left, use a 12 V battery to connect its (+) and (±) termi-
nals to terminal ªDº and Black lead wire (2) respectively. Then
motor (1) should rotate at 35 to 45 rpm.

2) TESTING AUTOMATIC STOP ACTION
a) First, connect battery (+) terminal to terminal ªDº and battery
(±) terminal to black lead wire (2) and let the motor (1) turn.
b) Then disconnect terminal ªDº from battery and let the motor
stop.
c) Next connect terminal ªDº and terminal ªAº with a jumper wire
(3) and connect terminal ªBº to battery (+) terminal. Observe the
wiper motor turns once again, then stops at a given position.
d) Repeat these steps several times, and inspect if the motor
stops at the given position every time.
Rear Wiper Intermittent Relay
[ON circuit]
1) Connect positive terminal of battery to terminals ª1º and ª4º of
relay, negative terminal to terminal ª5º of relay and check voltage
between terminals ª6º and ª5º of relay.
If measured voltage is battery voltage, relay is in good condition.
If not, replace relay.
2) Connect positive terminal of battery to terminal ª2º of relay, then
disconnect positive terminal from terminal ª4º of relay and check
voltage between terminals ª6º and ª5º of relay.
If measured voltage is battery voltage, relay is in good condition.
If not, replace relay.
3) Disconnect positive terminal from terminal ª2º of relay and check
voltage between terminals ª6º and ª5º of relay.
If measured voltage is about 0 V, relay is in good condition.
If not, replace relay.
[WASH circuit]
1) Connect positive terminal of battery to terminal ª1º of relay and
negative terminal to terminal ª5º of relay. Then connect positive
terminal to terminal ª7º checking voltage between terminals ª6º
and ª5º of relay.
If measured voltage changes from about 0 V to battery voltage
0.6 to 1.5 seconds after connecting positive terminal to terminal
ª7º, relay is in good condition. If not, replace relay.

2) Disconnect positive terminal from terminal ª7º checking voltage
between terminal ª6º and ª5º of relay.
If measured voltage changes from battery voltage to about 0 V
2.7 to 4.6 seconds after disconnecting positive terminal from ter-
minal ª7º, relay is in good condition.
If not, replace relay.
[INT circuit]
1) Connect positive terminal of battery to terminals ª1º of relay and
negative terminal to terminal ª5º of relay. Then positive terminal
to terminal ª3º of relay checking voltage between terminals ª6º
and ª5º of relay.
If measured voltage changes from about 0 V to battery voltage
when connecting positive terminal to terminal ª3º, relay is in
good condition.
If not, replace relay.
2) Connect positive terminal of battery to terminal ª2º of relay, then
disconnect positive terminal from terminal ª2º of relay checking
voltage between terminals ª6º and ª5º of relay.
If measured voltage changes from battery voltage to about 0 V
when disconnecting positive terminal from terminal ª2º and
about 0 V to battery voltage 8
2 seconds after disconnecting
positive terminal from terminal ª2º, relay is in good condition.
If not, replace relay.
