The description

When the vehicle stops or goes, if the difference of potentials between a conclusion of a signal of a sensor control "A 14" and a conclusion of grounding of a sensor control "A4" does not correspond to the established value of pressure or if pressure of a signal at a stop differs from pressure of a signal at driving, this is deduced КДН.

Thus, this КДН can be deduced, when the vehicle is lifted also its wheel () rotate. In that case dump КДН and check up again.

When the G-sensor control on a vehicle 2WD is established, this is deduced КДН.
When the lamp chain 4WD is opened or short-circuited on the earth, this is deduced КДН.
