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.

POWER DOOR LOCK CONTROLLER (CANVAS TOP
MODEL)
1) Disconnect power door lock controller coupler.
2) Connect (+) wire and (±) wire of 12 V battery to terminal ªAº, ªEº
and ªFº as shown in figure.
3) Disconnect cord from terminal ªEº and connect it to terminal ªGº.
4) Repeat Steps 2) and 3) several times and if relay operation is
heard every time, it means that controller is operating.
POWER DOOR LOCK CONTROLLER (HARD TOP MODEL)
1) With the driver side door key turned LOCK, check all power
doors are locked.
2) With the driver side door key turned UNLOCK, check only the
driver side power door is unlocked.
Turn the driver side door key to UNLOCK again within 5 se-
conds, check all power doors are unlocked.
If check result of Step 1) and Step 2) is satisfactory, power door lock
controller is OK. If check result is not satisfactory, go to next Step 3).
3) Disconnect negative cable at battery.
4) Disconnect coupler of power door lock controller.
5) Use a 12 V battery to connect its (+) terminal to terminal E02-1,
and its (±) terminal to terminal E02-2 and E02-3. Check all power
doors are locked.
If check result is not satisfactory, repair circuit and recheck.
If check result is satisfactory, go to next Step 6).
