DTC PROCEDURE

Step	Check	Yes	No
1 CHECK SI-DRIVE SWITCH. Turn the ignition switch to OFF. Disconnect the connector from the combination meter. Measure the resistance when the SI-DRIVE switch is operated. Connector & terminal (i10) No. 31 - Chassis ground:	Does the resistance change as below? S#/I: 1.71 - 1.89 kΩ S/I: less than 1 Ω	Go to step 5 .	Go to step 2 .
2 CHECK HARNESS BETWEEN COMBINATION METER AND SI-DRIVE SWITCH CONNECTOR. Measure the resistance of harness between combination meter connector and SI-DRIVE switch connector. Connector & terminal (i10) No. 31 - (ST3) No. 8:	Is the resistance less than 1 Ω?	Go to step 3 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between combination meter connector and SI-DRIVE switch connector Poor contact of coupling connector Poor contact of roll connector Roll connector is faulty
3 CHECK HARNESS BETWEEN SI-DRIVE SWITCH CONNECTOR AND CHASSIS GROUND. Measure the resistance of harness between SI-DRIVE switch connector and chassis ground. Connector & terminal (ST3) No. 7 - Chassis ground:	Is the resistance less than 1 Ω?	Go to step 4 .	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between SI-DRIVE switch connector and chassis ground Poor contact of joint connector Poor contact of roll connector Roll connector is faulty
4 CHECK HARNESS BETWEEN COMBINATION METER AND SI-DRIVE SWITCH CONNECTOR. Measure the resistance between combination meter connector and chassis ground. Connector & terminal (i10) No. 31 - Chassis ground:	Is the resistance 1 MΩ or more?	Repair the poor contact of SI-DRIVE switch connector. Replace the SI-DRIVE switch if defective. < Ref. to SI-DRIVE (SUBARU INTELLIGENT DRIVE) SELECTOR . >	Repair the short circuit to ground in harness between combination meter and SI-DRIVE switch connector.
5 CHECK HARNESS BETWEEN COMBINATION METER AND CHASSIS GROUND. Measure the resistance of harness between combination meter and chassis ground. Connector & terminal (i10) No. 38 - Chassis ground:	Is the resistance less than 5 Ω?	Go to step 6 .	Repair the open circuit of harness between combination meter and chassis ground.
6 RECHECK FAULT. Connect all connectors. Switch SI-DRIVE modes.	Is there any fault?	Repair the poor contact of combination meter connector. Replace the meter case assembly if defective. < Ref. to COMBINATION METER . >	The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
