1 CHECK COMBINATION METER. Turn the ignition switch to ON. (engine OFF) Check the warning light in the combination meter.	Does the warning light illuminate?	Go to step 2.	Repair or replace the combination meter. < Ref. to INSPECTION , Combination Meter System. >
2 CHECK HARNESS CONNECTOR BETWEEN COMBINATION METER AND OIL PRESSURE SWITCH. Turn the ignition switch to OFF. Disconnect the connector from oil pressure switch. Turn the ignition switch to ON. Measure the voltage of harness between oil pressure switch connector and chassis ground. Connector & terminal (E11) No. 1 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Replace the oil pressure switch. < Ref. to OIL PRESSURE SWITCH . >	Go to step 3.
3 CHECK COMBINATION METER. Turn the ignition switch to OFF. Remove the combination meter. Measure the resistance of combination meter. Terminals No. 2-No. 19:	Is the resistance less than 10 Ω?	Repair the harness and connector.
