DTC Code DTC Name
C1B03 Actuator Angle Neutral Malfunction

DESCRIPTION

When the DRS ECU (rear steering control ECU) detects a problem with the actuator angle neutral position, DTC C1B03 is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Return-to-normal Condition
C1B03 Actuator Angle Neutral Malfunction When neutral position memorization is performed, the actuator neutral position is deviated (the stroke sensor detects an angle that is not between 170° and 190°). Rear steering link assembly Comes on Power switch on (IG) again

CAUTION / NOTICE / HINT

Note

If the rear steering link assembly or the rear suspension is removed and installed, replaced, or adjusted, after performing actuator calibration value initialization, perform neutral position memorization and motor rotation angle sensor calibration.
