CHECK COMMON RAIL PRESSURE.

Read the data of “Target Common Rail Pressure” and “Common rail pressure” using Subaru Select Monitor.

NOTE:

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

QUESTION

Does “Common rail pressure” change in response to “Target Common Rail Pressure”?

Yes No

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

Inspect using “Diagnostic Procedure without Diagnostic Trouble Code (DTC)”.
