What does it mean when the dashboard lights up after the engine starts?

When the dashboard lights up after the engine starts, it may indicate that the vehicle's system is performing a self-check. Typically, the indicator lights will illuminate for about 3-4 seconds after turning on the ignition and then turn off, indicating that the vehicle's electronic control system is functioning normally. If the self-check indicator light does not illuminate or remains lit, it suggests a fault in the vehicle's electrical system. For example, if the engine self-check indicator light stays on, it indicates an engine fault that requires immediate inspection and repair. Below is relevant information about vehicle indicator lights: 1. Oil pressure indicator: This light displays the oil pressure inside the engine. It lights up during the vehicle's self-check and turns off after startup. If the light remains on, it means the engine oil pressure is below the specified standard and requires maintenance. 2. Coolant temperature indicator: This light primarily shows the temperature of the coolant in the engine. It lights up for a few seconds during the vehicle's self-check and remains off under normal conditions. If the coolant temperature exceeds the specified value, the vehicle should be stopped immediately for inspection and repair.
