NOTE:

Subaru select monitor is also available for monitoring
information other than that used for check and repair of the
vehicle.

F42 (Maximum and minimum EGR system pressure
value) will not read accurately until the EGR flow diagno-
sis terminates.
EGR flow diagnosis terminates when LED No. 2 illuminates
at function mode FA4.

*1: “Hi” or “Low” is shown instead of measured value.

Because ASV solenoid valve, FICD solenoid valve and
air injection system diagnosis solenoid valve are not
installed, FD06, FD09 and FD11 will be displayed but non-
functional.
