Solenoid valve This actuator is to convert electrical signal into linear movement Two types of solenoid valves are used in the vehicle One is directly driven with linkage e g the magnetic switch of starter motor The other is for controlling pressure and flow by transferring the movement to relevant valves For example in engine intake air control electronically controlled automatic transmission suspension control etc Motor DC motor is the most popular actuator used in automobile It can be divided into two types according to its use One is rotated by power e g windshield wiper seat adjuster etc The other is used in servo mechanism In this situation external force makes the rotor rotate around the stator e g the servo motor for LAUNCH damper Besides the two types listed above there are other types such as relay electronic switch etc Self diagnosis of Electronic Control System All modern cars are controlled by an Electronic Control Unit ECU The main purpose of the electronic control system is to provide maximum engine performance with the least amount of air pollution and the best fuel efficiency possible However the complexity of the system may increase the difficulty for its troubleshooting The function of self diagnosis is for solving such problem with electronic control system Working Principle of Self diagnosis The composition of self diagnosis system is similar to electronic control
