The monitor runs after coldstart with large valve lift during engine idle and vehicle speed at zero. A second phase of engine idle and vehicle speed at
zero is needed after coldstart. In both phases the position of the camshaft has to be static.

The diagnosis is disabled at:

-

power stage error of solenoid valves

-

oil temperature out of limits
