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 (Marking: HEAD) CONTINUITY
If continuity is not as specified, replace the relay.







4. INSPECT HEADLIGHT DIMMER RELAY(Marking: DIM) CONTINUITY
If the continuity is not as specified, replace the relay.







5. INSPECT TAILLIGHT CONTROL RELAY (Marking: TAIL) CONTINUITY
If continuity is not as specified, replace the relay.







6. INSPECT DAYTIME RUNNING LIGHT RELAY (MAIN) CIRCUIT
Disconnect the connector from the relay and inspect the connector on the wire harness side, as shown in the chart.

If result is as specified, try replacing the relay with a new one.
If result is not as specified, inspect the circuits connected to other parts.







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




8. INSPECT SIDE MARKER LIGHT CONTINUITY
Using an ohmmeter, check that continuity exists between terminals.
If continuity is not as specified, replace the light assembly or bulb.
