Cruise Control Switch Circuit

CRUISE CONTROL SWITCH CIRCUIT

CIRCUIT DESCRIPTION
The cruise control main switch operates seven functions: SET, COAST, TAP-DOWN, RESUME, ACCEL, TAP-UP, and CANCEL. The SET, TAP-DOWN and COAST functions, and the RESUME and, TAP-UP ACCEL functions share the same switch. Each function can be controlled by moving the switch in the directions of the arrows on the cruise control main switch assy. The switch will return automatically after being released.

The internal contact point of the cruise control main switch is turned on with the switch operation. Then the hybrid vehicle control ECU reads the voltage value which has been changed by the resistance in the switch in order to control SET, COAST, RESUME, ACCEL, and CANCEL.
