I. About the product 
Understand the working principle of the electric power steering system. The training box integrates the main original components of the electric power steering system and the corresponding power steering system circuit diagram. By regulating simulated vehicle speed and engine speed signals, the magnitude and direction of steering wheel force under different vehicle speed conditions are compared. The digital instrument displays the force magnitude, with positive and negative values indicating the direction of power assistance, thereby understanding the working conditions and process of real vehicle power steering. Measure the working parameters of related components on the wiring diagram and the bare electronic power steering unit control panel, and read the data flow and fault code of the power steering system through the OBDII diagnostic socket to gain a deep understanding of the working principle of the electric power steering system.
