10.SPORT Indicator Light Display

A: OPERATION

When any on-board diagnostics item is malfunctioning, the display on the SPORT indicator light blinks from
the time the malfunction is detected after starting the engine until the ignition switch is turned OFF. The mal-
functioning part or unit can be determined by a DTC during the on-board diagnostics operation. Problems
which occurred previously can also be identified through the memory function. If the SPORT indicator light
does not show a problem (although a problem is occurring), the problem can be determined by checking the
performance characteristics of each sensor using Subaru Select Monitor. Indicator light signal patterns are
as shown in the figure.

Perform the inspection when the SPORT indicator light does not operate correctly. <Ref. to 4AT(diag)-23, IN-
SPECTION, SPORT Indicator Light Display.>
