If there is a malfunction with an on-board diagnosis part, the ATF temperature warning light will flash. The flashing will continue from when the malfunction is confirmed after starting the engine, until the ignition switch is turned to OFF. The malfunctioning part or unit can be identified by DTC during the on-board diagnostics operation. Problems which occurred previously can also be identified through the memory function. If the ATF temperature warning 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 the Subaru Select Monitor. The ATF warning light signal patterns are shown in the figure.
