AUTOMATIC TRANSMISSION (DIAGNOSTICS)
10.AT Oil Temp Warning Light Display
A: OPERATION
When any on-board diagnostics item is malfunctioning, the ATF temperature warning light blinks when a mal-
function is detected after starting the engine until the ignition switch is turned OFF. The malfunctioning 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 ATF temperature warning light does not
show a problem (although a problem is occurring), the problem can be determined by checking the perfor-
mance characteristics of each sensor using the Subaru Select Monitor. Indicator light signal patterns are as
shown in the figure.
