Why is the dashboard off light always on?
2 Answers
The off light in the vehicle's dashboard is the anti-skid deactivation warning light. When this light is on, it serves to remind the driver that the vehicle's anti-skid system has been turned off. At this point, the driver can continue to drive cautiously or pull over as soon as possible to reactivate the vehicle's anti-skid function. Below is relevant information: 1. Definition of the vehicle anti-skid system: The vehicle anti-skid system uses an ABS/ASR electronic control unit to determine the wheel slip rate and vehicle speed based on signals from the wheel speed sensors. The electronic control unit adjusts the throttle opening and brake pressure to regulate the wheel slip rate, preventing the vehicle from skidding during driving. 2. Situations for using the anti-skid system: The vehicle's anti-skid system is enabled by default. The system primarily analyzes information from sensors to ensure optimal dynamic balance during driving. In rainy or snowy conditions, the anti-skid system may be temporarily turned off, as the vehicle is prone to skidding on snow-covered or heavily waterlogged roads. In such cases, the vehicle's computer will automatically detect wheel slippage and limit engine power output to a necessary extent.
I've been driving for many years, and it's really common to see the dashboard OFF light staying on! I remember one time when the light suddenly stayed on while I was driving—it was because the vehicle stability control system had been manually turned off. There's a button near the steering wheel labeled ESC Off or something similar, which might have been accidentally pressed or stuck and didn't spring back. If it wasn't manually turned off, then an electronic system issue should be considered, such as a faulty sensor, dust blocking the signal, or unstable battery voltage causing the control module to misjudge. After turning off the stability system, the car is prone to skidding in rainy, snowy conditions or during sharp turns, which is dangerous. I suggest first checking the button by toggling it a few times. If that doesn’t work, head to a repair shop immediately to scan for trouble codes with a diagnostic tool—don’t risk driving further.
