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 Volt?
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 Volt 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.
