What does it mean when the car SVS light is on?
1 Answers
When the car SVS light is on, it indicates that the engine control unit has detected an error signal from a certain sensor or that the sensor has exceeded the standard usage range. When the ignition switch is turned on, the car SVS indicator light will illuminate for an automatic check and then turn off after a few seconds. If the SVS light remains on, you can try to see if the engine can start normally. If it can, this may rule out issues with the fuel pump. The SVS fault indicator is a warning light that appears when the ECU (Engine Control Unit) or TCU (Transmission Control Unit) of an electronically fuel-injected car detects a problem with the engine or automatic transmission. Therefore, all electronically fuel-injected cars have an SVS fault indicator light. For manual transmission cars, it serves as the engine fault indicator, while for automatic transmission cars, it indicates both engine and automatic transmission faults.
