What does it mean when the key light on the dashboard keeps flashing?
1 Answers
The flashing key light on the dashboard indicates that the anti-theft system has been activated. When this indicator light is on, the car cannot be started. The anti-theft system is designed to prevent the car from being stolen and to protect valuable items inside the vehicle. This system mainly consists of electronic control circuits, alarm devices, remote control keys, mechanical keys, and actuators. Common warning lights on the dashboard include: oil pressure warning light, engine fault warning light, coolant temperature warning light, brake system fault light, tire pressure warning light, battery warning light, power steering system fault light, and electronic stability control system indicator. Reasons for warning lights to illuminate include: 1. Poor fuel quality; 2. Dirty engine cylinders with carbon deposits; 3. Damaged, poorly connected, or interrupted signals from coolant temperature sensors, crankshaft position sensors, air flow sensors, intake air temperature sensors, or oxygen sensors; 4. Clogged air filter element.
