Caution / Notice / Hint

NOTE:
  • When replacing the DRS ECU (rear steering control ECU), perform neutral position memorization and motor rotation angle sensor calibration.

    Refer to CALIBRATION [09/2020 - ]

  • Since DTC C15C9 is stored in the VGRS ECU (front steering control ECU), after performing repairs on the dynamic rear steering system, clear the DTCs for the VGRS system. (When DTC C1B23 is output, the VGRS ECU [front steering control ECU] does not store DTC C15C9.)
