●Check continuity using an ohmmeter.
●Diode is functioning properly if test results are as shown in the
figure at left.
●Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer toDI-44,
"Wiring Diagram — WARN —/ LHD Models" orDI-50, "Wiring
Diagram — WARN — / RHD Models" .

FRONT WIPER AND WASHER SYSTEM
FRONT WIPER AND WASHER SYSTEM
PFP:28810
System DescriptionEKS0032N
WIPER OPERATION
The wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:
●LO speed
●HI speed
●INT (Intermittent)
With the ignition switch in the ON or START position, power is supplied
●through 20A fuse [No. 6, located in the fuse block (J/B)]
●to front wiper motor terminal 4.
LOW AND HIGH SPEED WIPER OPERATION
Ground is supplied to front wiper and washer switch terminal 17 through body grounds E24 and E50.
When the wiper switch is placed in the LO position, ground is supplied
●through terminal 14 of the front wiper and washer switch
●to front wiper motor terminal 3.
With power and ground supplied, the wiper motor operates at low speed.
When the wiper switch is placed in the HI position, ground is supplied
●through terminal 16 of the front wiper and washer switch
●to front wiper motor terminal 1.
With power and ground supplied, the wiper motor operates at high speed.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided
●from terminal 14 of the front wiper and washer switch
●to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
Ground is also supplied
●through terminal 13 of the front wiper and washer switch
●to front wiper motor terminal 2
●through terminal 6 of the front wiper motor, and
●through body grounds E24 and E50.
When wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected instead of ter-
minals 6 and 2. Wiper motor will then stop wiper arms at the STOP position.
INTERMITTENT OPERATION
The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 1 to 13
seconds. This feature is controlled by the wiper amplifier (INT SW) combined with front wiper and washer
switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier.
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with front
wiper and washer switch.
Then intermittent ground is supplied
●through wiper amplifier (OUTPUT) and
●through terminal 14 of front wiper and washer switch
●to front wiper motor terminal 3
The wiper motor operates at low speed at the desired interval.
WASHER OPERATION
With the ignition switch in the ON or START position, power is supplied
●through 20A fuse [No. 6, located in the fuse block (J/B)]
●to front washer motor terminal 1.
When the lever is pulled to the WASH position, ground is supplied
