Why is the car dashboard not displaying?

[Don]

Car dashboard not displaying is due to poor contact at the battery terminals. Below are the specific introductions to dashboard indicator lights: 1. Indicator Lights: Such as turn signal lights, parking lights, etc., their function is to indicate the status of various vehicle functions. 2. Warning Lights: Warning lights serve an alert function, such as fuel indicator lights, door status indicator lights, seatbelt indicator lights, etc. Generally, warning lights turn off after the driver performs the corresponding action, for example, the seatbelt indicator light turns off once the driver fastens the seatbelt. 3. Fault Indicator Lights: Such as generator fault indicator lights, ABS fault indicator lights, transmission fault indicator lights, etc. Normally, these fault indicator lights rarely light up, or they may light up briefly when starting the engine and then turn off. If a fault indicator light stays on continuously accompanied by a warning sound, it indicates that the vehicle has a malfunction or abnormality.
