What does it mean when the ignition switch is in the ON position?
1 Answers
The ignition switch in the ON position means that all basic equipment except the starter is functioning normally. If the key is also in the ON position, all components of the vehicle are powered, including the engine system. The dashboard lights will illuminate, and the fuel pump will begin to build oil pressure. After approximately 5 to 10 seconds, when the fuel pump has fully built oil pressure, the dashboard needles will return to their original positions. Finally, pressing the start switch will start the vehicle. Meanings of other ignition switch positions: LOCK is for locking the car. Generally, when the key is placed in this position, the steering wheel is locked and cannot be moved significantly. ACC provides power to the entire vehicle, allowing the radio, lights, etc., to function normally, but the air conditioning cannot be used. The control process of the car's ignition switch: When the ignition switch is in the "OFF" position, turning the key to the "OFF" (shut) position connects the two internal contact points in the horizontal position, which means the external wires "black-white wire" and "green wire" are connected. If you measure the two wires with an ohmmeter at this time, they should be in a conductive state. In the actual vehicle, the connection of these two wires indicates that the entire circuit system has stopped working, the ignition system circuit is in a short-circuit state, and the engine is turned off.
