- CHECK DTC
.
Using the Subaru Select Monitor or a general scan tool, read the DTC of [Engine]. Ref. to COMMON (DIAG)>DIAGNOSTIC TROUBLE CODE (DTC) .
Is DTC other than P0617 displayed? (Current malfunction)
Yes: Check the appropriate DTC using the "Diagnostic Trouble Code (DTC)". Ref. to ENGINE (DIAGNOSTICS) (H4DO 2.0 (EXCEPT FOR HEV))>DIAGNOSTIC TROUBLE CODE (DTC) .
No: Go to 2.
- CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) (SHORT TO POWER SUPPLY)
.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Turn the ignition switch to ON.
- Measure the voltage between ECM connector and engine ground.
Connector and terminal
(B134) No. 27 (+) - Engine ground (-):
Is the voltage 10 V or more?
Yes: Repair the short circuit to power supply in harness between ECM connector and M/B (starter relay).
No: Repair the poor contact of ECM connector.
