Check Power Supply And Ground Circuit

DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK POWER SUPPLY FOR COMBINATION METER. Remove the combination meter. Refer to REMOVAL , Combination Meter. Disconnect the combination meter harness connector. Turn the ignition switch to ON. Measure the voltage between combination meter connector and chassis ground. Connector & terminal (i10) No. 3 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 2 .	Check the harness for open or short between the ignition switch and combination meter.
2 CHECK POWER SUPPLY FOR COMBINATION METER. Measure the voltage between combination meter connector and chassis ground. Connector & terminal (i10) No. 1 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 3 .	Check the harness for open or short between the fuse and combination meter.
3 CHECK GROUND CIRCUIT OF COMBINATION METER. Turn the ignition switch to OFF. Measure the resistance of harness between combination meter connector and chassis ground. Connector & terminal (i10) No. 15 - Chassis ground: (i10) No. 16 - Chassis ground:	Is the resistance less than 10 Ω?	Replace the meter case assembly.	Repair the wiring harness.
