Vehicle speed sensor
A/C switch (if equipped)
ELECTRIC SHIFT CONTROL SYSTEM
POWER TRAIN CONTROL MODULE (PCM)
The power train control module controls the shift solenoid A and the
shift solenoid B by sending electric signals to them so as to attain
automatic gear shift between the 1st and 2nd gears, and the 2nd
and 3rd gears. Equipped as PCM sensed parameters are the
1
throttle position sensor, transmission range switch and vehicle
speed sensor. These sensors sense the throttle valve opening, se-
lect lever's position and vehicle speed, and send those signals to
the power train control module. Then, the power train control mod-
ule opens and closes valves of the above solenoids according to
these signals.
