DESCRIPTION

INSPECTION PROCEDURE

CLEAR DTC

PERFORM VGRS SYSTEM CALIBRATION

CHECK FOR DTC

DTC C1592/52 Actuator Neutral Position Calibration Incomplete


DESCRIPTION

The VGRS ECU (steering control ECU) first checks the actuator angle neutral point calibration flag after entering test mode. If the ECU detects that steering actuator angle neutral point calibration is incomplete twice, it stores DTC C1592/52.

DTC No.
