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. The vehicle-to-vehicle distance set value can be changed by operating the steering pad switch (distance control switch) while the dynamic radar cruise control system is in operation. The steering pad switch uses the BEAN to communicate with each ECU. Therefore it does not have a direct connection with the hybrid vehicle control ECU. If there are any malfunction in the communication line of the steering pad switch, one or more DTCs in the multiplex communication system are output.
