8-22 BODY ELECTRICAL SYSTEM
INSPECTION
Check for continuity between terminals at each switch position as
shown below.
If check result is not as specified, replace.
INTERMITTENT WIPER RELAY CIRCUIT INSPECTION
1) Turn the front wiper switch to “INT” position.
2) Connect battery positive terminal to terminal “B3” and its
negative terminal to terminal “HE”
3) Connect voltmeter positive lead to terminal “H” and its nega-
tive lead to terminal “HE”.
4) Check that the voltmeter indicates the battery voltage (10 -
14 V).
5) Connect terminal “AS” and terminal “B3” by a jumper wire.
6) When “B3” and “HE” are shorted by other jumper wire, check
that voltage changes as shown in figure.
If check result is not satisfied, replace.

WASHER LINKED CIRCUIT INSPECTION
1) Make sure that front wiper switch is at “OFF” position.
2) Connect battery positive terminal to terminal “B3” and its
negative terminal to terminal “HE”.
3) Connect voltmeter positive lead to terminal “H” and its nega-
tive lead to terminal “HE”.
4) When front washer switch is ON (pushed to forward), check
that voltage changes as shown in figure.
FRONT WIPER MOTOR
INSPECTION
Motor Operation (Low Speed)
1) Connect battery positive terminal to terminal “L” and its neg-
ative terminal to motor bracket (wiper ground).
2) Check motor revolution speed as specification.
Front wiper motor specification (at low speed)
: 44 - 52 r/min (rpm)
Motor Operation (High Speed)
1) Connect battery positive terminal to “H” and its negative ter-
minal to motor bracket (wiper ground).
2) Check motor revolution speed as specification.
Front wiper motor specification (at high speed)
: 64 - 78 r/min (rpm)

Automatic Stop Operation
1) Connect battery positive terminal to terminal “L” and its neg-
ative terminal to motor bracket (wiper ground) and let the
motor turn.
2) Disconnect terminal “L” from battery positive terminal, and
let the motor stop.
3) Connect terminal “L” and “S” with a jumper wire, and connect
terminal “B” to battery positive terminal. Observe the motor
turns once again then stops at a specified position.
4) Repeat Step 1) to 3) several times and check that the motor
stops at the specified position every time.
If check result is not satisfied, replace.
WASHER TANK AND WASHER PUMP
REMOVAL
1) Disconnect negative cable at battery.
2) Remove front fender lining (RH).
3) Remove washer tank attaching nuts and inlet pipe (4).
4) Disconnect pump lead wire coupler(s) and hoses.
5) Remove washer tank (1).
6) Remove front washer pump (2) and rear washer pump (3) (if
equipped) from washer tank (1).
INSTALLATION
Reverse removal procedure for installation.
INSPECTION
1) Connect battery (+) and (-) terminals to pump (+) and (-) ter-
minals respectively.
2) Check motor operation for both front and rear (if equipped)
washer pump.

REAR WIPER AND WASHER SWITCH (IF EQUIPPED)
INSPECTION
Check for continuity between terminals at each switch position as
shown below.
If check result is not as specified, replace.
REAR WIPER MOTOR
INSPECTION
Wiper Motor
Use a 12 V battery to connect its (+) and (-) terminals to terminal
“L” and terminal “E” respectively. Then motor should rotate at 35
to 45 rpm.
Automatic Stop Operation
1) Connect battery positive terminal to terminal “L” and its neg-
ative terminal to terminal “E” and let the motor turn.
2) Disconnect terminal “L” from battery positive terminal and let
the motor stop.
3) Connect terminal “B” to battery positive terminal. Observe
the motor turns once again then stops at a specified position.
4) Repeat Step 1) to 3) several times, and check that the motor
stops at the specified position every time.
