PROBLEM TO BE SOLVED: To provide a control system which suppresses generation of malfunction in a micro computer.SOLUTION: A control system includes:a micro computers (10,20) with memories (12,22) for storing applications and reprogrammings and CPU (11,21) which runs on the basis of an application or a reprogramming; and a rewriter (40) which successively rewrites pieces of data stored in each of memories in multiple micro computers one by one. Each CPU of the multiple micro computers in an application mode determines whether a communication among the multiple micro computers is normal, and when determining that it is not normal, the CPU determines whether a transition command to transit the CPU from the application mode to a reprogramming mode was input from the rewriter within a first prescribed time. When the transition command was input within the first prescribed time, the mode is transited to the reprogramming mode. |
