Connector & Terminal (B135) No.25 (+) - Chassis Ground (-):

2. Measure voltage between ECM and chassis ground.

CHECK: Is the voltage more than 2 V?

YES: Repair harness and connector.

NOTE:
In this case, repair the following:
- Open circuit in harness between ECM connector and engine grounding terminal
- Poor contact in engine grounding terminal
- Poor contact in coupling connector (B21)

NO: Go to step 10DE2.

10DE2: CHECK POOR CONTACT.
Check poor contact in ECM connector.

CHECK: Is there poor contact in ECM connector?

YES: Repair poor contact in ECM connector.

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.
