Inspection Procedure

NOTE:
  • When replacing the DRS ECU (rear steering control ECU), perform neutral position memorization and motor rotation angle sensor calibration. Refer to CALIBRATION [09/2013 - ] .
  • Since DTC C15C9/76 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 C1B23/33 is output, the VGRS ECU [front steering control ECU] does not store DTC C15C9/76.)
