What Causes a Car to Not Shut Off?
1 Answers
The main reason a car won't shut off is due to a faulty ignition switch that fails to cut power. Here's more information about ignition switches: 1. The ignition system's switch (usually operated with a key) freely opens or closes the main circuit of the ignition coil, and also applies to other electrical circuits. 2. The ignition switch has ACC position, ON position, and START position. Turning to ACC position powers the vehicle's electrical equipment such as audio system and lights. The ON position powers the ABS (Anti-lock Braking System), AIRBAG (airbag system), fuel pump, and ECU working power supply. START position means to start the engine.
