Caution / Notice / Hint

NOTE:
  • When replacing the VGRS ECU (front steering control ECU), perform actuator angle neutral position calibration and initialization after replacement (Refer to CALIBRATION [09/2014 - ] ).
  • Since DTC C1B09/19 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.
