ELECTRONIC POWER STEERING SYSTEM PRECAUTION


  1. HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM Click here

  2. PRECAUTION FOR REMOVAL, INSTALLATION AND REPLACEMENT OF ELECTRONIC MOTOR POWER STEERING COMPONENTS


    1. When handling electronic parts:


      1. Avoid any impacts to electronic parts such as ECUs and relays. Replace with new ones if dropped or subjected to a severe blow.

      2. Do not expose any electronic parts to high temperatures or humidity.

      3. Do not touch the connector terminals, to prevent deformation or malfunctions due to static electricity.

      4. When the power steering ECU assembly has been replaced with a new one, perform a steering zero point calibration Click here.

    2. When handling the steering column assembly:


      1. Avoid any impact to the steering column assembly, especially to the motor and torque sensor. Replace with new parts if dropped or subjected to a severe blow.

      2. Do not pull on the wire harness when moving the steering column assembly.

      3. When the steering column assembly has been replaced, perform a steering zero point calibration after initializing the steering zero point calibration signal Click here.

    3. When disconnecting and reconnecting the connectors:


      1. When disconnecting the connector related to the electric power steering system, turn the ignition switch ON, center the steering wheel, turn the ignition switch OFF, and then disconnect the connector.

      2. When reconnecting the connector related to the electric power steering system, ensure that the ignition switch is OFF. Center the steering wheel and then turn the ignition switch ON.

        Note

        Do not turn the ignition switch ON when the steering wheel is not centered.

      3. If the above operations are not carried out properly, the steering center point (zero point) will deviate, which may lead to a difference in steering effort between turning right and left. If there is a difference in steering effort between turning right and left, perform a steering zero point calibration Click here.
