Why does the BYD SVS light stay on and the car won't move when shifting gears?
1 Answers
BYD SVS light staying on and the car not moving when shifting gears indicates that the engine control unit has detected an error signal from a certain sensor or that it has exceeded the usage standard. When the ignition switch is turned on, the car's SVS indicator light will illuminate for an automatic check and then turn off after a few seconds, which is normal. If it stays on, it indicates a fault in the car's electronic control system. Here is an introduction to the car's electronic control system: 1. Electronic Control Unit (ECU): The core of the control system, it is a microcomputer containing integrated circuits and other precise electronic components. 2. Sensors: Car sensors are located in various positions of the car and their main function is to provide the control system with information about the car's operating conditions, such as engine speed, throttle opening, coolant temperature, etc. 3. Actuators: Devices that perform corresponding actions based on the electrical signals output by the electronic control unit.
