Auto-cruise control indicator light
It generates a pulse signal proportional to vehicle speed (revolving
speed of the transaxle output gear).
It receives signals from the vehicle speed sensor and each switch,
and uses a micro-computer to control all functions of the auto-cruise
control.
It drives the motor-driven vacuum pump according to signals from the
control unit and adjusts the throttle valve via the intermediate link to
the set opening.
Switch for cruise control power.
Vehicle speed is set with the SET (COAST) switch and RESUME (AC-
CEL) switch.
It is used to cancel the setting of the cruise speed
It outputs a signal to cancel cruise control
It generates an analog voltage proportional to throttle opening.
Based on the valve of throttle position sensor voltage when the idle
switch goes from ON to OFF, it varies throttle position sensor voltage
to compensate for fluctuations.
If the scan tool or a voltmeter is connected, diagnostic test mode and
input check codes from the control unit can be read.
It is in the combination meter and lights up when the auto-cruise con-
trol functioning.
