CHECK DTC.

1) Clear the memory using the Subaru Select Monitor or general scan tool.

2) Perform the “Inspection Mode” to check DTC.

QUESTION

Is the same DTC as current diagnosis output?

Yes No

Replace the ECM.

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.
