Why do several dashboard lights turn on after the car is powered on?
1 Answers
It is normal for several warning lights to illuminate on the dashboard after the car is powered on. This is part of the vehicle's self-check process, as the onboard computer performs diagnostics when power is connected. These warning lights will turn off after the self-check is completed. Typically, only the battery and handbrake indicators remain lit at this stage, with the battery light extinguishing once the engine starts running. There's no need for excessive concern. Below is an introduction regarding warning lights: 1. Location of warning indicators: Warning lights are generally located within the dashboard display in the driver's compartment. 2. Function of warning indicators: Their purpose is to alert the driver when a system malfunction occurs during normal vehicle operation, prompting attention and service at designated repair stations. 3. Types of warning indicators: These include the engine warning light, airbag system warning light, ABS system warning light, and transmission control system warning light. 4. Structural principle of warning indicators: Composed of bulbs, self-diagnostic systems, and fault circuits, they can promptly identify malfunctioning components when system failures occur, at which point the warning light will illuminate.
