A method for diagnosing a coolant circuit control in a vehicle and cooling circuit with such a cooling circuit control

摘要

The invention relates to a method for diagnosing a coolant circuit control (2) in a vehicle, wherein the cooling circuit control (2) has a valve (6) which, by means of an actuator (40) is controlled, whose position is measured by a position value (p) of a position sensor (42) is determined, in a first, the starting of the vehicle during a plausibility check of phase a functionality of the actuator (40), the starting operation and then in a position is measured and the corresponding position value (p) with at least one limit value (g) is compared. The present invention furthermore relates to a cooling circuit (8) with such a cooling circuit control (2).
