B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

With the ignition SW turned on, the current flows to TERMINAL 17 of the wiper and washer SW, TERMINAL 2 of the washer
motor and TERMINAL 2 of the front wiper motor through the WIPER fuse.
1. LOW SPEED POSITION
With the wiper and washer SW turned to LO position, the current flows from TERMINAL 17 of the wiper and washer SW to
TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run
at low speed.
2. HIGH SPEED POSITION
With the wiper and washer SW turned to HI position, the current flows from TERMINAL 17 of the wiper and washer SW to
TERMINAL 8 to TERMINAL 3 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run
at high speed.
3. INT POSITION
With the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL 17 of the
wiper and washer SW to TERMINAL 2 to GROUND. This activates the intermittent circuit and the current flows from
TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to
GROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in the
relay.
4. WASHER CONTINUOUS OPERATION
With the wiper and washer SW pulled to WASHER position (Washer SW ON position), the current flows from the WIPER
fuse to TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 of the wiper and washer SW to TERMINAL 2 to
GROUND and causes the washer motor to run and the window washer to spray. Simultaneously, current flows from the
WIPER fuse to TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to
TERMINAL 4 to GROUND, causing the wiper to function.
