VARIABLE GEAR RATIO STEERING SYSTEM, Diagnostic DTC:C1592/52

DTC Code DTC Name
C1592/52 Actuator Neutral Position Calibration Incomplete

DESCRIPTION

The VGRS ECU (front 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. Detection Item DTC Detection Condition Trouble Area Warning Indicate Return-to-normal Condition
C1592/52 Actuator Neutral Position Calibration Incomplete The VGRS ECU (front steering control ECU) detects that steering actuator angle neutral point calibration is incomplete twice.

  • Steering actuator assembly

  • VGRS ECU (front steering control ECU)

 Comes on After clearing DTCs, perform actuator angle neutral point calibration.

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.
