Check Power Supply And Ground Circuit

WARNING: This page is about a different car, the 2007 Subaru Outback and 2007 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.

DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 CHECK POWER SUPPLY FOR COMBINATION METER. Remove the combination meter. <Ref. 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. 1 (+) - Chassis ground (-): (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 (-): (i10) No. 3 (+) - 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 Normal meter model: (i10) No. 11 - Chassis ground: (i10) No. 12 - Chassis ground: Multi information display model: (i10) No. 11 - Chassis ground: (i10) No. 12 - Chassis ground:	Is resistance less than 10 Ω?	Replace the meter case assembly.	Repair the wiring harness.
