< Mode B (measurement of reference pressure for setting the target negative pressure)>
WARNING: This page is about a different variant/trim than selected.
Judgment 1
Judge the reference pressure stability.
Judge as NG when the following conditions are established.
Judgment 2
Judge whether the reference pressure is within the normal range, and detect the vacuum pump and orifice malfunctions.
Judge as NG when the following conditions are established.
