Caution / Notice / Hint

NOTE:
  • When replacing the VGRS ECU (front steering control ECU) or steering actuator assembly, perform actuator angle neutral point calibration and initialization after replacing parts.

    Refer to CALIBRATION [09/2020 - ]

  • Since DTC C1B09 is stored in the DRS ECU (rear steering control ECU), after performing repairs on the VGRS system, clear the DTCs for the dynamic rear steering system.

    Refer to DTC CHECK / CLEAR [09/2020 - ]
