What does the steering wheel with an exclamation mark mean?
1 Answers
The steering wheel with an exclamation mark indicates a problem with the vehicle's power steering system. When the yellow light comes on, it means the steering system is partially malfunctioning, and more force is required to turn the steering wheel. If the red light comes on, it indicates a complete failure of the steering system, where the power assist system cannot provide any assistance, and all the force to turn the steering wheel must come from the driver's hands. Normally, when the ignition switch is turned from OFF to ACC, the electric power steering system warning light will briefly illuminate for self-check. If no issues are found, it will turn off. The electric power steering system is a power steering system that directly relies on an electric motor to provide auxiliary torque. It mainly consists of a torque sensor, speed sensor, electric motor, reduction mechanism, and electronic control unit.
