The auto-cruise control system performs control functions for
the setting or cancellation of the fixed-speed driving speed
based upon the data provided by input signals. As a result,
when the auto-cruise control system is canceled by abnormal
system operation, the cause of the cancellation is memorized
in a separate circuit by the ECU, thus providing the ECU with
the on-board diagnostic function by certain fixed patterns, as
well as the function of being able to check whether or not the
ECU's input switches or sensor are normal. Thus, by effectively
using these function, the time required checking and repair can
be shortened.
