AUTO-CRUISE CONTROL SWITCH
The auto-cruise control switch is built into the steering column
switch.MAIN SWITCH
The MAIN switch is an automatic reset type switch to turn ON
and OFF the power supply of the control unit.
COMMAND INPUT SWITCHES (SET and RESUME)
The SET and RESUME switches function to input the control
signals of the auto-cruise control system; both are the
automatic-reset type.
These switches are ON while pressed and OFF when released.
For the ECU’s input interface, each of the input terminals is
pulled up by the battery voltage; the terminal voltage is LOW
level
(OV) when the switch is ON, and is HIGH level (about 12V)when the switch is OFF. These voltage changes (digital
sig*)are input to the microcomputer as ON and OFF signals

Ft2iFu~The transaxle control system is composed of
various type of sensors, the transaxle control
unit.and the hydraulic control device, and it functions for
(1) damper clutch control, (2) shift pattern
Control.and (3) hydraulic control, during shifting.
%, In other words, data signals received
fromthe
.$ various sensors enable the driving conditions to beJ-
sj.q’74:i.&f’detected, and, based upon the preset damper clutch
engaging range, shift pattern and hydraulic pattern,
the damper clutch control solenoid valve, the shift
Control solenoid valve and the pressure control
solenoid valve are driven, which assures that a good“feeling” during shifting is maintained.
