P0079:00

•  Inhibits the two-stage turbo control.

•  Inhibits the EGR control.

•  The fast idle up correction for the idle speed control is inhibited.

•  Inhibits engine-stop by operating the i-stop function.

P0080:00

•  Inhibits the two-stage turbo control.

•  Inhibits the EGR control.

•  The fast idle up correction for the idle speed control is inhibited.

•  Inhibits engine-stop by operating the i-stop function.

•  PCM restricts engine-transaxle integration control.
