C2413 Motor current fail - General Information

Component Location





General Description

The EHPS (Electro Hydraulic Power Steering) system is to assist a driver's steering force by using a motor and making an oil pressure, not by engine power.
The MPU-Motor lets a hydraulic pump operate and makes a hydraulic pressure which is necessary for steering wheel's operation. It also controls the steering power according to vehicle speed.
The MPU ECU controls its motor speed with signals such as a vehicle speed and a steering angle sensor.

DTC Description

The MPU compares the calculated current value based on torque with the measured current value.
The MPU sets this code if the different value between them is over a certain specification.
