Abstract
An ignition control system has an airbag control device and a roll-over control device. The airbag control device and the roll-over control device are interconnected by a communication line. The specification of communication between the control devices is set so that the operation of the airbag control device is the same when the roll-over control device is provided as it would be were the roll-over control device not provided. When a roll-over of the vehicle occurs, first and second switching element are turned on, so that ignition current is supplied from a backup capacitor. During diagnostics, the second switching element remains off.
