What does the flashing red key on the dashboard mean?
1 Answers
The flashing red key icon on the dashboard is the anti-theft system indicator light, and continuous flashing indicates that the anti-theft system is activated. Below are the components of the dashboard: Components of the car dashboard: Speedometer and odometer: Consists of two gauges. One is the speedometer, and the other is the odometer. Tachometer: The tachometer is usually located inside the instrument panel, placed symmetrically with the speedometer and odometer. The tachometer operates based on magnetic principles. It receives pulse signals generated when the primary current in the ignition coil is interrupted and converts these signals into a displayable RPM value. The faster the engine speed, the more pulses the ignition coil generates, resulting in a higher RPM value displayed on the gauge. Indicator and warning lights: Timing belt indicator, exhaust temperature warning light, brake warning light, anti-lock braking system (ABS) warning light, etc. Oil pressure gauge: The sensor of the oil pressure gauge is a piezoresistive sensor. It is threaded and fixed to the engine oil line. Oil pressure pushes a contact slide along a resistor, changing the resistance and thereby affecting the current flow through the gauge to ground, which moves the pointer.
