Electronic Power Steering - C1604 ECU Error - General Information

Component Location





General Description




EPS has a solenoid valve on power steering gear box, and a EPS CM underneath the audio center facia. EPS CM which receives signals from VSS (Vehicle Speed Sensor) and TPS controls the oil flow of steering gear box. EPS CM performs the conventional power steering function in case a failure has occurred in the system.
EPS CM electronically controls the current to the solenoid of by-pass valve by inputting sensor's signals to control the hydraulic amount in cylinder chamber and thereby varying the steering effort versus the hydraulic pressure according to vehicle speed.

DTC Description

This DTC is about general error of inside EPS CM. If this DTC is set, check unstable power or excessive surge influx by faulty power supply and chassis ground.
