A communication control apparatus of the present invention controls communication among a plurality of electronic devices mounted on a vehicle and mainly includes a control unit that is configured of a micro computer or the like and that periodically outputs clock pulses, a trouble detecting unit to detect a trouble in the control unit, and a communication control unit to interrupt communication upon detection of a trouble, that is, to control communication by disconnecting an electronic device. The trouble detecting unit includes an analog amount converting unit to convert clock pulses from the control unit to an analog amount and an analog amount comparing unit to compare the analog amount generated in the analog amount converting unit with a predetermined threshold.
