5. A/T OIL TEMP. WARNING
When the oil temp. sensor (A/T) 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 GAUGEfuse 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 operation and the warning light goes out.
