2) TESTING AUTOMATIC STOP ACTION
a) First, connect battery (+) terminal to terminal "D" and battery
(–) terminal to black lead wire (2) and let the motor (1) turn.
b) Then disconnect terminal "D" from battery and let the motor
stop.
c) Next connect terminal "D" and terminal "A" with a jumper wire
(3) and connect terminal "B" 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 "1" and "4" of
relay, negative terminal to terminal "5" of relay and check voltage
between terminals "6" and "5" 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 "2" of relay, then
disconnect positive terminal from terminal "4" of relay and check
voltage between terminals "6" and "5" of relay.
If measured voltage is battery voltage, relay is in good condition.
If not, replace relay.
3) Disconnect positive terminal from terminal "2" of relay and check
voltage between terminals "6" and "5" 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 "1" of relay and
negative terminal to terminal "5" of relay. Then connect positive
terminal to terminal "7" checking voltage between terminals "6"
and "5" 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
"7", relay is in good condition. If not, replace relay.
