1. The vehicle is equipped with SRS (Supplemental Restraint System) such as airbags. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing. This may cause a serious accident. Before servicing (including inspection, replacement, removal and installation of parts), be sure to read the precautionary notices for the Supplemental Restraint System (Click here).

  1. When handling the steering column assembly:

    1. Avoid any impact to the steering column assembly, especially to the motor or the torque sensor. Replace the steering column assembly with a new one if it is dropped or subjected to any severe impacts.

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

    3. Hold the motor and housing section when carrying the steering column assembly. Do not hold the shaft or the tilt lever so as not to damage the steering column assembly.

    4. After replacing the steering column assembly, power steering motor assembly or power steering ECU assembly, clear the rotation angle sensor calibration value, initialize the rotation angle sensor, and calibrate the torque sensor zero point (Click here).

  2. When disconnecting or reconnecting the connectors:

    1. When disconnecting connectors related to the electronic motor power steering system, turn the ignition switch ON (the engine is stopped), center the steering wheel, turn the ignition switch off, and then disconnect the connectors.

    2. When reconnecting connectors related to the electronic motor power steering system, make sure that the ignition switch is turned off, center the steering wheel and then turn the ignition switch ON (the engine is stopped).

      Do not turn the ignition switch ON without the steering wheel being centered.
    3. If the above operations are not carried out correctly, the steering center point (zero point) will deviate, causing a difference in steering effort between right and left turns. If there is a difference in the steering effort between right and left turns, perform the steering center point adjustment (zero point calibration) (Click here).
