The solution to the problem of electronic power steering system includes the following steps:
Check the generator and power supply: Make sure that the generator is working properly and the power supply is stable. If the generator fails, it needs to be replaced or repaired.
Check the power pump: Check whether the power pump has abnormal sound, overheating or leakage. If there is a problem, the power pump may need to be replaced.
Check the steering system connection: Make sure that the various connection parts of the steering system such as pipes, joints and wires are tight and not loose. If there is any looseness, tighten or replace it.
Check the air in the steering system: If there is air in the steering system, it may cause abnormal steering. The air can be released through the exhaust valve, or special tools can be used for exhaust operation.
Check the steering gear piston cylinder, oil seal and control valve: Check whether these parts are damaged. If damaged, they need to be replaced or repaired.
Check the steering hydraulic line: Check whether there are foreign objects in the line, such as dust, grease, etc. If there are foreign objects, the line needs to be cleaned to prevent the steering pump flow control valve from getting stuck.
The causes of the failure may include sensor failure, steering gear failure, power pump failure, lack of oil in the system or air mixed in, etc. Due to the complex structure of the EPS system, involving high voltage and precision electronic components, it is difficult for non-professionals to accurately determine the cause of the failure and make effective repairs. Therefore, it is recommended that drivers contact professional automobile maintenance institutions as soon as possible for professional technicians to conduct comprehensive inspections and repairs.
In order to prevent the occurrence of EPS system failures, drivers should regularly maintain and service the vehicle, including checking the power oil level, cleaning sensors and line connections, etc. At the same time, pay attention to driving habits, avoid frequent sudden steering or keeping the vehicle in extreme steering conditions for a long time.
