Abstract
A control system comprises a reset unit for outputting a reset output by the manipulation of a manually operable member, a first microcomputer adapted to be reset by the reset output, a second microcomputer, and a controller for deactivating the second microcomputer. The controller deactivates the second microcomputer in accordance with the outputs of the first microcomputer and the second microcomputer. When there is no output from the second microcomputer, the controller deactivates the second microcomputer in response to the output of the first microcomputer determining no response from the second microcomputer.
Claims4
