Wiper and Washer System

INSPECTION







1. INSPECT FRONT WIPER AND WASHER SWITCH CONTINUITY
If continuity is not as specified, replace the switch.




2. INSPECT REAR WIPER AND WASHER SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







3. Connector disconnected:
INSPECT WIPER AND WASHER SWITCH CIRCUIT
Disconnect the connector from the motor and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.




4. Low speed:
INSPECT FRONT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 5, check that the motor operates at low speed.
If operation is not as specified, replace the motor.

5. High speed:
INSPECT FRONT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 5, check that the motor operates at high speed.
If operation is not as specified, replace the motor.




6. Stopping at stop position:
INSPECT FRONT WIPER MOTOR OPERATION
a. Operate the motor at low speed and stop the motor operation anywhere except at the stop position by disconnecting positive (+) lead from terminal 1.
b. Connect terminals 1 and 3.
c. Connect the positive (+) lead from the battery to terminal 2 and negative (-) lead to terminal 5, check that the motor stops running at the stop position after the motor operates again.
If operation is not as specified, replace the motor.







7. Connector disconnected:
INSPECT FRONT WIPER MOTOR CIRCUIT
Disconnect the connector from the motor and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.




8. INSPECT FRONT WASHER LINKED OPERATION
a. Connect the positive (+) lead from the battery to terminal 16 and the negative (-) lead to terminal 2.
b. Connect the positive (+) lead from the voltmeter to terminal 7 and the negative (-) lead to terminal 2.




c. Push in the washer switch, and check that the voltage changes as shown in the table.





9. INSPECT REAR WIPER MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 3 and negative (-) lead to terminal 1 and the motor body, check that the motor operates.




b. Disconnect the negative (-) lead from terminal 1, check that the motor stops running at the stop position.
If operation is not as specified, replace the motor.




10. Intermittent:
INSPECT REAR WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 2 and the motor body, check that the motor operates intermittently for 9-15 seconds. If operation is not as specified, replace the motor.







11. Connector disconnected:
INSPECT REAR WIPER MOTOR CIRCUIT
Disconnect the connector from the motor and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.




12. Sedan:
INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, check that the motor operates.

NOTE: 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.







13. Sedan, Connector disconnected:
INSPECT FRONT WASHER MOTOR CIRCUIT
Disconnect the connector from the motor and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the power source, wire harness and wiper switch.




14. Wagon:
INSPECT FRONT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, check that the motor operates.

NOTE: 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.




15. INSPECT REAR WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 3, check that the motor operates.

NOTE: 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.







16. Wagon, Connector disconnected:
INSPECT WASHER MOTOR CIRCUIT
Disconnect the connector from the motor and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the power source, wire harness and wiper switch.
