If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according to a predetermined accelerator angle to make driving possible. And if there are malfunctions in tow systems, the accelerator opening angle is controlled by the idle signal sent from the ECM which is based on input indicating either idle condition or off-idle condition (predetermined accelerator opening) in order to make driving possible.
