5. A/T OIL TEMP. WARNING
When the A/T Oil Temp. Sensor affixed to the transmission case detects that the fluid temp. is 150°C (302°F) or more, the Engine Control
Module operates and the current flowing through the GAUGE fuse flows to the A/T Oil Temp. warning light to TERMINAL OIL-W of the
Engine Control Module to GROUND, so that the warning light lights up, informing that the Oil Temp. is high. When the Oil Temp. drops to 120°
C (248°F) or less, the Engine Control Module stops operating and the warning light goes out.
