Niro Steering - frk2/opencaret GitHub Wiki

The steering system of the Kia is an Electric Power Assisted Steering (EPAS) system. The steering column contains a high current DC motor, as well as a torque sensor. The torque sensor measures the direction and amount of force on the steering wheel and outputs an Analog signal to the EPAS microprocessor. The microprocessor then controls the motor to "assist" the vehicle steering.

Below is a wiring diagram showing the connection between the EPAS in Kia Niro.

Below are the pinouts for the MDPS and the location of MDPS in Niro.
