Component Tests and General Diagnostics

INSPECTION







1. INSPECT TURN SIGNAL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







2. INSPECT COMBINATION SWITCH CIRCUIT
Connect the wire harness side connector to the combination switch and inspect wire harness side connector from the back side.
If the circuit is not as specified, inspect the circuit connected to other parts.




3. INSPECT TURN SIGNAL FLASHER OPERATION
a. Connect the positive (+) lead from the battery to terminals 1 and 4, and the negative (-) lead to terminal 7.
b. Connect 2 turn signal bulbs to terminal 2 and 3 each and connector the other side of them to negative (-) battery terminal.
c. Check that the LH bulbs flushes when terminal 5 is connected to the negative (-) battery terminal.
d. Check that the RH bulbs flushes when terminal 6 is connected to the negative (-) battery terminal.




e. Disconnect the terminal 1 from the positive (+) battery terminal.
f. Check that LH and RH bulbs flush when terminal 8 is connected to the negative (-) battery terminal.







4. INSPECT TURN SIGNAL FLASHER CIRCUIT
Disconnect the connector from the combination switch and inspect the connector on the wire harness side, as shown.
If circuit is as specified, replace the relay.
If circuit is not as specified, inspect the circuits connected to other parts.







5. INSPECT HAZARD WARNING SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







6. INSPECT HAZARD WARNING SWITCH CIRCUIT
Disconnect the switch connector and inspect the connection on the wire harness side.
If the circuit is not as specified, inspect the circuits connected to other parts.
