ABSTRACT:
The contents of a ROM are highly reliably changed while the ROM is attached to a substrate. A vehicle control device has an electrically programmable nonvolatile memory storing a vehicle control program. A ROM update process includes a collation in which a check is made to determine whether the updating of the ROM was correctly executed. An abnormal process ensures an output from the control device clearly is an abnormal control amount under even ordinary vehicle drive conditions.
