Troubleshooting of the EPS
The electric power steering consists of a mechanical part, a control unit and an electric motor. Problems with the control units are less common, as these components are protected from environmental hazards. However, faults can occur in both the mechanical part of the system and the control unit.
Let's look at the most common EPS faults:
- Wear of the threads of the upper shaft, on which the steering wheel is fixed, becomes the cause of axial play and knocking of the steering wheel;
- Wear of the upper shaft support bushing also causes backlash and knocking in the rudder;
- If the upper shaft support bearing has rusted or is starting to deteriorate, it causes play, unpleasant sounds, grinding when cornering and driving on rough roads;
- Wear of the unit housing bracket mounts will cause play of the housing and shaft, knocking;
- If the cross members between the shafts are covered with rust, the steering wheel will start to wedge, there will be knocks and grinding when turning the steering wheel;
- When the protective elements on the column are loosened, a squeak will be heard when driving;
- The soot that has appeared on the copper elements of the drive will interfere with the work of the amplifier;
- If the steering wheel sensor is out of order, then the power steering stops working;
- When the settings of the control unit, it becomes the cause of errors in the amplifier.
