CHECK HARNESS BETWEEN ECM AND COMMON RAIL PRESSURE SENSOR CONNECTOR.

1) Connect the connector to ECM.

2) Start the engine.

3) Read the data of common rail pressure signal using Subaru Select Monitor or general scan tool.

NOTE:

• Subaru Select Monitor

For detailed operation procedures, refer to “READ CURRENT DATA FOR ENGINE”.

• General scan tool

For detailed operation procedures, refer to the general scan tool operation manual.
