Manual Description
(SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 3, service Notice and Precautions EPS System 3, pOWER STEERING CONTROL SYSTEM 15 STC, ePS Motor, Torque Sensor, Reduction Gear 6.

EPS SYSTEM : System Description 8, ePS SYSTEM : Protection Function 9, ePS WARNING LAMP DOES NOT TURN ON 32, ePS WARNING LAMP DOES NOT TURN.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" "SEAT BELT, the Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER”, used along, with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death.

The event of a collision which would result in air bag inflation, all maintenance must be performed by, improper maintenance, including incorrect removal and installation of the SRS, can lead personal, injury caused by unintentional activation of the system, pRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS.

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near sensor(s) with, when using air or electric power tools or hammers, always switch the Ignition OFF, disconnect, battery and wait at least three minutes before performing any service, service Notice and Precautions EPS System.

Check the following item when performing trouble diagnosis, - Check any possible causes by interviewing the symptom and it′s condition from the customer if any malfunction, such as EPS warning lamp turned ON, occurs, - Check if air pressure and size of tires are proper, the specified part is used for the steering wheel, and control unit genuine part, - Check if the connection of steering column assembly and steering gear assembly is proper (there not.

Looseness of mounting bolts, damage of rods, boots or sealants, and leakage grease, etc, - Check if the wheel alignment adjusted properly, - Check if there is any damage or modification to suspension or body resulting in increased weight altered, - Check if installation conditions of each link suspension proper.

- Check if the battery voltage proper, - Check connection conditions of each connector proper, - Before connecting or disconnecting the EPS control unit harness connector, turn ignition switch OFF”, during quick steering, rasping noise may be heard from around the steering wheel.

The noise is an operating noise of the EPS system under normal conditions, the location of the noise repair, necessary, ePS control unit (view with steering, ePS motor (view with steering column removed vehicle).

ABS actuator and electric unit (control unit), "EPS Motor, Torque Sensor, Reduction Gear", "WARNING/INDICATOR/CHIME LIST : Warning Lamp, transmits mainly the following signals to EPS control unit via.

Transmits mainly the following signal to EPS control unit via, ePS control unit via CAN communication, ePS control unit (1) is installed steering column assembly, ePS control unit performs an arithmetical operation data, such.

As steering wheel turning force (sensor signal) torque, assist torque signal to the EPS motor according driving condition, ePS control unit decreases the output signal EPS motor while, extremely using the power steering function (e.

Consecutively for protecting EPS motor EPS control unit, ePS Motor, Torque Sensor, Reduction Gear, ePS motor torque sensor (2) and reduction gear (3) installed, ePS motor provides the assist torque by the control signal EPS control unit.

Torque sensor detects the steering torque, and transmits the signal EPS control unit, reduction gear increases the assist torque provided from EPS motor with worm gears, and outputs column shaft, extensive steering at low speed will cause EPS control unit.
