What does it mean when the car EPS light is on?

[SanVincent]

When the car EPS light is on, it indicates a fault in the electric power steering system. If accompanied by abnormal conditions such as heavy steering wheel turning, steering noise, steering wheel shaking, or poor steering wheel return ability, it is not advisable to continue driving. If none of the above-mentioned abnormal conditions occur, you can safely stop the car and restart the engine to resolve the issue. The EPS is a power steering system that relies on electric assistance to provide auxiliary torque, and its function is to assist the driver in steering operations. Based on the steering torque signal from the steering wheel and the vehicle speed signal, the electronic control unit adjusts the motor to generate an appropriate amount and direction of auxiliary force.
