Component Tests and General Diagnostics

INSPECTION




1. INSPECT LIGHT CONTROL SWITCH CONTINUITY




If continuity is not as specified, replace the switch.

2. INSPECT HEADLIGHT DIMMER SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




3. INSPECT HEADLIGHT CONTROL RELAY CONTINUITY




If continuity is not as specified, replace the relay.




4. INSPECT TAILLIGHT CONTROL RELAY CONTINUITY




If continuity is not as specified, replace the relay.




5. INSPECT HEADLIGHT DIMMER RELAY CONTINUITY




If continuity is not as specified, replace the relay.

6. INSPECT DOOR COURTESY SWITCH

7. Light-On Warning System: INSPECT INTEGRATION RELAY OPERATION




a. Connect the positive (+) lead from the battery to terminal 12 and the negative (-) lead to terminal 7.
b. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 5.




c. Check that the buzzer does not sound when terminal 4 or 5 is connected to the positive (+) lead.
d. Check that the buzzer does not sound when disconnecting terminal 4 or 5.
If operation is not as specified, replace the relay.

Terminal Identification:

8. INSPECT DAYTIME RUNNING LIGHT RELAY CIRCUIT
Disconnect the connector from the relay and inspect the connector on the wire harness side.




If circuit is as specified, perform inspections.




9. INSPECT DAYTIME RUNNING LIGHT NO.4 RELAY CONTINUITY




If continuity is not as specified, replace the relay.




10. INSPECT DAYTIME RESISTOR RESISTANCE CONTINUITY




If continuity is not as specified, replace the resistor.
