How to check the Electric Power Steering

Checking the Electric power steering (EPS) consists of the following operations:

• Dismantle the rack from the car and place it on the desktop.
• Connect the controller with the appropriate diagnostic cable to diagnose the EPS and the steering rack.
• Run on the tablet special software, which automatically determines the model of the rack being tested.
• With the help of the software we supply power and an ignition signal on the rack.
• By rotating the drive shaft of the steering gear, we determine the presence or absence of amplification. In this case, the software interface will show the amount of current consumed by the electric booster.
• Using the built-in or external diagnostic software, we read the error codes from the memory of the rack control module. Based on the data obtained, we draw conclusions about the cause of the malfunction and possible ways of solving the problem.
• After the necessary repair operations, we re-diagnose the rack and remove the irrelevant error codes.
• Install the unit on the car and, if necessary, calibrate it.
