Tacoma Regular Cab 4WD V6-3.4L (5VZ-FE) (1997)
operation causes gear shift when the conditions for overdrive are met.
^
O/D Main SW OFF
When the O/D main SW is turned to OFF, the current flowing through the O/D OFF indicator light flows through the O/D main SW to
GROUND, causing the indicator light to light up. At the same time, a signal is input to TERMINAL OD2 of the Engine Control Module and
Engine Control Module operation prevents shift into overdrive.
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 --> TERMINAL OIL-W of the
Engine Control Module --> 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.
