diagnostic system for the operation of a elektroventils, aboard a vehicle was booked

摘要

The system has a unit (3) applying a test control signal to an electro valve (1), and a unit (4) acquiring a signal from a unit (2) that recopies the position of the valve. A unit (4) finds response time of the valve to the control signal. A unit (5) compares the response time with a preset threshold value for detecting a malfunctioning of the valve. A unit verifies that the voltage of a battery embarked onboard a vehicle is correct, the speed of the vehicle is null, and the speed of rotation of an engine is lower than a preset threshold valve, for validating the testing of the valve.
