Turn Signals: Testing and Inspection

PARTS LOCATION





TROUBLESHOOTING
The table below will be useful for you in troubleshooting these electrical problems. The most likely causes of the malfunction are shown in the order of their probability. Inspect each part in the order shown and replace the part when it is found to be faulty.

COMBINATION SWITCH INSPECTION








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





2. INSPECT SWITCH CIRCUIT
(a) Pull the spool body forward and separate spool body from steering column.
(b) Connect the wire harness side connector to the combination switch and inspect the wire harness side connect or from the back side, as shown.





Turn Signal Switch Circuit
If the circuit is not as specified, inspect the circuits connected to other parts.

TURN SIGNAL FLASHER INSPECTION





1. INSPECT FLASHER OPERATION
(a) Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 3.
(b) Connect the 2 turn signal light bulbs parallel to each other to terminals 1 and 3, check that the bulbs flash.

HINT: The turn signal lights should flash 60 to 120 times per minute.

If one of the front or rear turn signal lights has an open circuit, the number of flash rate will be more than 140 per minute.
If operation is not as specified, replace the flasher.








2. INSPECT FLASHER CIRCUIT
Remove the relay from the relay block and inspect the connector on relay block side as shown.
If the circuit is not as specified, inspect the circuits connected to other parts.

HAZARD WARNING SWITCH INSPECTION








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








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