What is an EPS module?
The EPS control module (CM) calculates the optimum assist current based on the steering torque signal from the torque sensor installed to the steering column and the vehicle speed signal sent via CAN transmission from the PCM. The following steering angle signals are output via CAN communication.
How does electric power steering ( EPS ) work?
The EPS control module also receives a vehicle speed input that, in combination with the steering position and torque sensors, combine to produce steering feedback to the driver. The position and torque sensors might also provide an electric input to safety-related systems like the vehicle stability control system (VSC), if so equipped.
What are the parts of an electric steering system?
In other configurations, the EPS module, steering torque and steering position sensors can be individually replaced. Although configurations might vary, the basic electric steering system consists of the power steering control module, assist motor, torque sensor and steering position sensor.
How does an electromechanical assist steering system work?
The vehicle speed input modulates steering sensitivity in relation to vehicle speed. The electromechanical assist is usually a directionally controlled, pulse-modulated electric motor that is geared into the steering shaft. Diagnostics on any EPS system should begin by scanning the EPS module for diagnostic trouble codes.
Where is the power steering control module located?
In another configuration, the EPS assembly is inserted between the steering wheel and the steering rack (see photo above). No matter what the configuration, the power steering control module receives inputs from a steering position sensor and a steering torque sensor that is mounted on the steering rack input shaft.
