1. CHECK SI-DRIVE SELECTOR. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the connector from the combination meter.
   3. Measure the resistance between connectors when the SI-DRIVE selector is operated.

   Connector & terminal

   (i10) No. 26 - (i10) No. 35:

   Does the resistance change as below?

   S#: 3.48 - 3.85 kΩ

   I: 0.95 - 1.05 kΩ

   S: less than 1 Ω

   Yes:  Go to  4.

   No:  Go to  2.

2. CHECK HARNESS BETWEEN COMBINATION METER AND MULTI-SELECT SWITCH CONNECTOR. 
   1. Disconnect the connector from multi-select switch.
   2. Measure the resistance of harness between combination meter and multi-select switch connector.

   Connector & terminal

   (i10) No. 26 - (R33) No. 5:

   (i10) No. 35 - (R33) No. 8:

   Is the resistance less than 1 Ω?

   Yes:  Go to  3.

   No:  Repair the harness and connector.

   NOTE: In this case, repair the following item:
   • Open circuit in harness between combination meter and multi-select switch connector
   • Poor contact of coupling connector
3. CHECK HARNESS BETWEEN COMBINATION METER AND MULTI-SELECT SWITCH CONNECTOR. 

   Measure the resistance between multi-select switch connector and chassis ground.

   Connector & terminal

   (R33) No. 5 - Chassis ground:

   (R33) No. 8 - Chassis ground:

   Is the resistance 1 MΩ or more?

   Yes:  Repair the poor contact of multi-select switch connector. Replace the multi-select switch if defective. Refer to FUEL INJECTION (FUEL SYSTEMS) (STI)>SI-DRIVE (SUBARU INTELLIGENT DRIVE) SELECTOR .

   No:  Repair the ground short circuit in harness between combination meter and multi-select switch connector.

4. 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?

   Yes:  Go to  5.

   No:  Repair the open circuit of harness between combination meter and chassis ground.

5. RECHECK FAULT. 
   1. Connect all connectors.
   2. Switch SI-DRIVE modes.

   Is there any fault?

   Yes:  Repair the poor contact of combination meter connector. Replace the combination meter if defective. Refer to INSTRUMENTATION/DRIVER INFO>COMBINATION METER .

   No:  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.
