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. w/ Daytime running light:
INSPECT TAILLIGHT DIMMER RELAY CONTINUITY
If continuity is not as specified, replace the relay.

Terminal Identification:

5. Connector Disconnected:
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.







6. Connector Connected:
INSPECT DAYTIME RUNNING LIGHT RELAY CIRCUIT
Connect the wire harness side connector to the relay and inspect wire harness side connector from the back side, as shown.
If circuit is not as specified, try replacing the relay with a new one.







7. INSPECT DAYTIME RUNNING LIGHT RELAY NO.4 CONTINUITY
If continuity is not as specified, replace the relay.







8. INSPECT DAYTIME RESISTOR CONTINUITY
If continuity is not as specified, replace the resistor.
