Power Steering Control Module (PSCM) When the steering wheel is turned, the PSCM uses signal voltage from the torque sensor to detect the amount of torque being applied to the steering column shaft and the amount of current to command to the EPS motor.Click to see full answer. Beside this, what does a steering control module do?That control module will sense the position of the steering wheel, note which direction the steering wheel is turning, and how fast is is being turned. Also, the control module senses the speed of the vehicle, angle of headlights, and many other factors relating to driver control of the vehicle.Additionally, what causes electric power steering failure? Most of the time this is caused by a problem with the steering angle sensor. Your vehicle’s electronic power steering system (EPS) relies on a computer-controlled electric motor to operate the steering rack. The control module for the EPS system has detected a fault in the system. Just so, what is a power steering module? An electric power steering module is more than just a circuit board and connectors in an aluminum box. The module contains the drivers, signal generators and MOSFET switches that power and control the electric motor. The module also contains a current monitor circuit that measures the amps the motor is using.How is electric power steering diagnosed? Diagnosis tips Diagnosis tips. • Noise or vibration in steering wheel: Check power steering gear, steering column. • Move the steering wheel toward the shaft and in four right angle directions to inspect for looseness and play. Verify that the equipped tire size and tire air pressure is as specified.
