What does the SVS light indicate?

[DeCody]

SVS indicator light on indicates that there is a fault in the vehicle's engine. The SVS indicator light is the engine fault indicator light, which is equivalent to the "engine shape" indicator light. When the vehicle's ignition key is turned on, this light will illuminate and will turn off after the vehicle starts. When the engine ECU detects a fault, the SVS light will illuminate. If this light comes on while the vehicle is in motion, it indicates that there is a fault in the vehicle's engine. The reasons for the engine fault indicator light being on are as follows: 1. Poor combustion state. Poor combustion in the engine not only pollutes the environment but also leads to fuel waste and excessive engine wear. 2. Poor fuel quality. 3. Dirty engine cylinder interior or carbon deposits. After a certain period of use, some carbon deposits will accumulate inside the engine. These deposits are unstable and retain heat, which can cause uncontrolled ignition in the engine, leading to engine knocking.
