WIRING DIAGRAM

11BS1: CHECK OUTPUT SIGNAL FROM ECM.

1. Start engine, and warm-up the engine.
2. Turn ignition switch to OFF.
3. Disconnect connector from TCM.
4. Turn ignition switch to ON.

Connector & Terminal - [(B134) No.31 (+) - Chassis Ground (-)]:





5. Measure voltage between ECM and chassis ground.

CHECK: Is the voltage less than 3 V?

YES: Go to step 11BS2.

NO: Repair battery short circuit in harness between ECM and TCM connector. After repair, replace ECM.

11BS2: CHECK HARNESS BETWEEN ECM AND TCM CONNECTOR.

1. Turn ignition switch to OFF.

Connector & Terminal - [(B134) No.31 (+) - Chassis Ground (-)]:





2. Measure voltage between ECM and chassis ground.

CHECK: Does the voltage change more than 10 V by shaking harness and connector of ECM while monitoring the value with voltage meter?

YES: Repair battery short circuit in harness between ECM and TCM connector. After repair, replace ECM.

NO: Contact with Subaru of America (SOA) service.

NOTE: Inspection by Subaru of America's DTM is required, because probable cause is deterioration of multiple parts.
