DYNAMIC RADAR CRUISE CONTROL SYSTEM Distance Control Switch Circuit

DESCRIPTION

The distance control switch sets the vehicle-to-vehicle distance mode. The distance control switch is installed in the steering pad switch assembly (distance control switch). The vehicle-to-vehicle distance set value can be changed by operating the steering pad switch while the dynamic radar cruise control system is in operation. The steering pad switch assembly uses the CAN communication line to communicate with each ECU.
