B: ABNORMAL DISPLAY ON AT OIL TEMP
INDICATOR
When any on-board diagnostic item is malfunctioning, the
display on the AT OIL TEMP indicator blinks immediately
after the engine starts.
The malfunctioning part or unit can be determined by a
trouble code during on-board diagnostic operation. Prob-
lems which occurred previously can also be identified
through the memory function.
If the AT OIL TEMP indicator 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 select monitor.
Indicator signal is as shown in the figure.
WARNING:
Warning can be noticed only when the engine is ini-
tially started.
