Cruise Control Switch Circuit
Cruise Control Switch Circuit
DESCRIPTION
The cruise control main switch operates 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 operated in the directions of the arrows and turns off when it is released.
The internal contact point of the cruise control main switch is turned on with the switch operation. Then the ECM reads the voltage value that has been
changed by the switch operation to control SET, - (COAST), RES (RESUME), + (ACCEL), and CANCEL.
