3. INSPECT INTERMITTENT WIPER OPERATION
(a) Turn the wiper switch to INT position.
(b) Turn the intermitte nt time control switch to FAST position.
(c) Connect the positive (+) lead from the battery to terminal
B18 and the negative ( −) lead to terminal B16.
(d) Connect the positive (+) lead from the voltmeter to termi- nal B7 and the negative ( −) lead to terminal B16, and
check that the meter needle indicates battery positive
voltage.
(e) After connecting terminal B4 to termianl B18, connect B18 to terminal B16.
Then, check that the voltage rises from O volt to battery
positive voltage within time as follows.

If operation is not as specified, replace the switch.
4. INSPECT WASHER LINKED OPERATION
(a) Connect the positive (+) lead from the battery to terminal
B18 and the negative ( −) lead to terminal B16.
(b) Connect the positive (+) lead from the voltmeter to termi- nal B7 and the negative ( −) lead to terminal B16.
(c) Push in the washer switch. Check that the voltage
changes, as shown in the table.
If operation is not as specified, replace the switch.
5. INSPECT REAR WIPER RELAY CONTINUITY
(a) Check that there is no continuity between terminals 1 and
3.
(b) Check that there is continuity between terminals 2 and 3.
If continuity is not as specified, replace the relay.
6. INSPECT REAR WIPER RELAY OPERATION
(a) Connect the positive (+) lead from the battery to terminal 1 and the negative ( −) lead to terminal 6.
(b) Connect the positive (+) lead from the voltmeter to termi- nal 2 and the negative ( −) lead to terminal 6, and check
that the meter needle indicates to O V.
(c) Connect the positive (+) lead from the voltmeter to termi-
nal 3 and the negative ( −) lead to terminal 6, and check
that the meter needle indicates to battery positive voltage.
If operation is not as specified, replace the relay.

7. INSPECT REAR WIPER RELAY INTERMITTENT OP-
ERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative ( −) lead to terminal 4.
(b) Connect the positive (+) lead from the voltmeter to termi- nal 3 and the negative ( −) lead to terminal 4.
(c) After disconnecting the positive (+) lead from terminal 2,
connect it to terminal 1, and then, check that the meter
needle rises from O V to battery positive voltage within 6
to 10 seconds.
If operation is not as specified, replace the relay.
8. Low Speed: INSPECT FRONT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and
negative ( −) lead to terminal 1, and check that the motor oper-
ates at low speed.
If operation is not as specified, replace the motor.
9. High Speed:
INSPECT FRONT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (− ) lead to terminal 1, and check that the motor op-
erates at high speed.
If operation is not as specified, replace the motor.
10. Stopping at Stop Position: INSPECT FRONT WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor opera-
tion anywhere except at the stop position by disconnect-
ing positive (+) lead from terminal 3.

(b) Connect terminal 3 and 5.
(c) Connect the positive (+) lead from the battery to terminal
6 and the negative ( −) lead to terminal 1, and check that
the motor stops running at the stop position after the mo-
tor operates again.
If operation is not as specified, replace the motor.
11. Low Speed: INSPECT REAR WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and
negative ( −) lead to terminal 2, and check that the motor oper-
ates at low speed.
If operation is not as specified, replace the motor.
12. Stopping at Stop Position: INSPECT REAR WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor opera-
tion anywhere except at the stop position by disconnect-
ing positive (+) lead from terminal 3.
(b) Connect terminal 3 and 4.
(c) Connect the positive (+) lead from the battery to terminal 1 and the negative ( −) lead to terminal 2, and check that
the motor stops running at the stop position after the mo-
tor operates again.
If operation is not as specified, replace the motor.
13. INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (− ) lead to terminal 1, and check that the motor op-
erates.
NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
If operation is not as specified, replace the motor.
