(Relay Operation)
(a) Connect the positive (+) lead from the voltmeter to ter-
minal 7 and negative (±) lead to terminal 10.
(b) Check that there is battery voltage with light control
switch is turned on.
If operation is not as specified, replace the relay.If continuity is not as specified, replace the relay.
2. INSPECT DAYTIME RUNNING LIGHT RELAY
(Relay Circuit)
Disconnect the connector from the relay and inspect the
connector on the wire harness side as shown in the chart.
INSPECTION OF RELAY
1. INSPECT DIMMER RELAY (Continuity)
If circuit is as specified, inspect relay operation.
