Headlight Cleaner System

INSPECTION







1. INSPECT HEADLIGHT CLEANER SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







2. INSPECT HEADLIGHT CLEANER SWITCH CIRCUIT
Disconnect the switch connector and inspect the connector on wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.




3. INSPECT HEADLIGHT CLEANER RELAY OPERATION
a. Check that no continuity exists between terminals 2 and 5.
b. Connect the positive (+) lead from the battery to terminals 1 and 5, and the negative (-) lead to terminal 3.
c. Connect the negative (-) lead from the battery to terminal 4, and check that continuity exists between terminals 2 and 5 for 0.9 - 1.1 seconds, then no continuity exists.
If operation is not as specified, replace the motor.







4. INSPECT HEADLIGHT CLEANER RELAY CIRCUIT
Disconnect the connector from the relay and inspect the connector on wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.




5. INSPECT HEADLIGHT CLEANER 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.







6. INSPECT HEADLIGHT CLEANER MOTOR CIRCUIT
Disconnect the connector from the cleaner motor and inspect the connector on wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.
