1. CHECK DTC  .

   Read the engine DTC using the Subaru Select Monitor or general scan tool. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>READ DIAGNOSTIC TROUBLE CODE (DTC) .

   Is other than DTC P0616 displayed? (Current malfunction)

   Yes: Check DTC using "List of Diagnostic Trouble Code (DTC)". Ref. to ENGINE (DIAGNOSTICS) (H4DO)>LIST OF DIAGNOSTIC TROUBLE CODE (DTC) .

   No: Go to  2 .

2. CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR  .
   1. Turn the ignition switch to OFF.
   2. Remove the starter relay.
   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 connector.

      Connector & terminal 

      (B134) No. 46 - (B159) No. 4:

      NOTE: 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 connector
   • Poor contact of coupling connector
3. CHECK HARNESS BETWEEN ECM AND STARTER RELAY CONNECTOR  .

   Measure the resistance between ECM connector and chassis ground.

   Connector & terminal 

   (B134) No. 46 - 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 connector.
