Why did the eco light suddenly go off in the 2017 Leiling?
2 Answers
The sudden disappearance of the Leiling's eco light indicates that the car's energy-saving mode has been turned off. ECO stands for the car's energy-saving mode. Introduction to eco: Eco refers to the car's economical driving mode. It is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active eco driving mode and non-active eco driving mode. When the eco indicator light on the dashboard is on, it means the car's economical mode is activated. Non-active eco mode: The non-active eco mode does not have a dedicated button. When the eco indicator light on the dashboard is on, it serves merely as a reminder function. The eco mode automatically evaluates driving behavior. If the current driving operation achieves the optimal fuel supply, the eco indicator light will simultaneously appear on the dashboard.
I've driven a Toyota for many years and encountered the issue of the ECO light not turning on a few times. The main reasons could be that the ECO mode isn't activated, the button was accidentally turned off or stuck. Try pressing the ECO button on the center console to see if the light responds. Another issue could be the throttle sensor—the light only comes on when you press the pedal lightly, and it turns off if you drive too aggressively. Poor wiring contact or a blown fuse is also common. Open the engine compartment's fuse box, look for the small fuse labeled ECO, and replace it if it's blown. The simplest fix is to reset the system: disconnect the battery's negative terminal for five minutes after turning off the engine, then reconnect it. Sometimes, this resolves ECU software bugs, and the light returns to normal. The ECO light reminds you to drive fuel-efficiently. While it not lighting up doesn't affect driving, it's best to have it checked at a professional repair shop to avoid bigger issues. Regular maintenance can prevent these problems in the first place.
