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

DTC Code DTC Name
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. DTC Detection Condition Trouble Area
C1592/52 The VGRS ECU (steering control ECU) detects that steering actuator angle neutral point calibration is incomplete twice.

  • Steering actuator assembly

  • VGRS ECU (steering control ECU)

CAUTION / NOTICE / HINT
