Model Without Push Button Start

DTC detecting condition: 

Immediately at fault recognition

• Use the check board when measuring the ECM terminal voltage and resistance.

1. CHECK DTC  .

   Read the engine DTC using the Subaru Select Monitor or general scan tool. Ref. to ENGINE (DIAGNOSTICS) (EXCEPT FOR STI)>Read Diagnostic Trouble Code (DTC) .

   Is DTC other than P0616 displayed? (Current malfunction)

   Yes: Check DTC using "List of Diagnostic Trouble Code (DTC)". Ref. to ENGINE (DIAGNOSTICS) (EXCEPT FOR STI)>List of Diagnostic Trouble Code (DTC) .

   No: Go to  2.

2. CHECK HARNESS BETWEEN ECM AND STARTER RELAY 1 CONNECTOR  .
   1. Turn the ignition switch to OFF.
   2. Remove the starter relay 1.
   3. Disconnect the connector from ECM.
   4. Disconnect the connector from starter motor.
   5. Measure the resistance of harness between ECM connector and starter relay 1 connector.

      Connector & terminal 

      (B134) No. 8 - (B225) No. 1:

      NOTE: For CVT model, place the select lever in "P" range or "N" range.

   Is the resistance less than 1 Ω?

   Yes: Go to  3.

   No:

   NOTE: Check the following item and repair or replace if necessary.
   • Open circuit of harness between ECM connector and starter relay 1 connector
   • Poor contact of coupling connector
3. CHECK HARNESS BETWEEN ECM AND STARTER RELAY 1 CONNECTOR  .

   Measure the resistance between ECM connector and chassis ground.

   Connector & terminal 

   (B134) No. 8 - Chassis ground:

   Is the resistance 1 MΩ or more?

   Yes: Repair the poor contact of ECM connector.

   No: Repair the short circuit to ground in harness between ECM connector and starter relay 1 connector.
