When the accelerator pedal or brake pedal is pressed, the steering system is in working
state. When eliminating the gas in the steering pipeline, the steering system should be in
working state, turning the steering wheel slowly to the left and right limit positions, so that
the steering wheel can be deflected to the left and right limit positions. (Note: If abnormal
phenomena occur at this time, the power should be switched off immediately to find out the
reasons for eliminating the fault), so that the gas in the pipeline can be exhausted by rotating
left and right repeatedly several times.
