What does it mean when the SUS light on the dashboard is on?
1 Answers
The reason why the SUS yellow light on the car dashboard is on is due to an engine malfunction. This yellow light is the engine malfunction indicator. Reasons for the engine malfunction light to illuminate: 1. Poor combustion state: A poor combustion state in the engine is the main reason for the engine malfunction light to come on. In automotive design, to ensure the engine is in good working condition and to guarantee its normal operational lifespan, oxygen sensors are installed to monitor the engine's combustion state. If the combustion state is poor, it not only pollutes the environment but also leads to fuel wastage and excessive engine wear. 2. Poor fuel quality: The engine has specific requirements for fuel quality, especially as regulations increasingly demand higher performance from engines, thus raising the standards for fuel quality. In reality, some gas stations may not fully comply with these standards to provide fuel that meets the requirements of high-performance engines, leading to frequent occurrences of the engine malfunction light illuminating. 3. Dirty engine cylinder interior and carbon buildup: Over time, the engine interior inevitably accumulates carbon deposits. These deposits can alter the engine's design parameters and, due to their unstable nature and heat retention, can cause irregular ignition, leading to engine knocking. In such cases, the engine malfunction light will also come on.
