CRUISE CONTROL CRUISE CONTROL SYSTEM Cruise Control Switch Circuit

DESCRIPTION

The cruise control main switch is used to turn the cruise control system on and off, as well as operate 7 functions:
SET, - (COAST), TAP-DOWN, RES (RESUME), + (ACCEL), TAP-UP and CANCEL. The SET, TAP-DOWN and - (COAST)
functions, and the RES (RESUME), TAP-UP and + (ACCEL) functions are operated with the same switch. The cruise
control main switch is an automatic return type switch which turns on only while operating it in the direction of
each arrow and turns off after releasing it. The internal contact points of the cruise control main switch turn on
with switch operation. Then the ECM reads the voltage value that has been changed by the switch operation to
control the SET, - (COAST), RES (RESUME), + (ACCEL), and CANCEL functions.
