The electric stability control (ESC) disengagement indicator is located on the instrument panel. This light comes on when the ESC has been manually disengaged. If the light comes on while driving and the button has not been selected, it indicates that an error has been detected in the ESC system. In some cases, the ESC light comes on if your car is actively trying to maintain traction control.
If the ESC light stays on, it means that your vehicle is not under control. And if the ESC light stays on for an extended period of time, your ESC may be malfunctioning, or the system has been manually deactivated. The light on the dashboard can have multiple meanings, so it is important to understand how your particular system works. Generally, the light will come on when the computer is actively trying to maintain control.
This light will remain on only as long as the vehicle is not under control. If the light stays on constantly, it is likely that a malfunction has been detected or the system has been manually shut down. The reduction in fatal single-vehicle rollovers is the most dramatic, and drivers with ESC are 75% more likely to survive such accidents than drivers without ESC. ESC automatically applies the brakes to each of the car's wheels, preventing the vehicle from spinning or rolling away.
Suddenly the ESC light will come on and the vehicle will lose torque and slow to a speed of about 50 kilometres per hour. If the ESC light flashes when driving like this, it means that the system is activated and is trying to keep the vehicle under control. Although ESC can help reduce the risk of spinning and ploughing, it will not necessarily prevent your car from rolling over. If your ESC was manually deactivated, there is a button on your car that you can use to reactivate it.
In addition, ESC has a control unit that tracks the angle of your car's steering wheel, along with the rotation around the vertical axis of your vehicle. In short, ESC is supposed to help keep the vehicle moving in the same direction the driver wants to go. But the OP is saying that "slow acceleration is happening when ESC is off, which doesn't make sense. Systems like traction control and anti-lock brakes help us maintain control during acceleration and braking, but electronic stability control (ESC) is designed to prevent loss of control in other circumstances.
Electronic stability control (ESC) may also be referred to as electronic stability programme (ESP) or dynamic stability control (DSC). Under normal operating conditions, the ESC warning lamp should only come on when the car is started for a couple of seconds and then go out. The quickest way to find out why the stability control light comes on is to use a diagnostic scanner to read the codes for the stability and ABS modules.
