ELECTRONICALLY CONTROLLED BRAKE SYSTEM, Diagnostic DTC:C1345/66, C1368/67

DTC Code DTC Name
C1345/66 Linear Solenoid Valve Offset Learning Undone
C1368/67 Linear Solenoid Valve Offset Malfunction

DESCRIPTION

The skid control ECU stores and corrects the difference in each individual part such as the stroke sensor, actuator solenoids. Perform initialization of the linear solenoid valve and calibration if these parts are replaced.

The DTCs are canceled when the result of linear valve offset learning is normal.

DTC Code Information Code DTC Detection Condition Trouble Area
C1345/66 - Value of initialization of linear solenoid valve and calibration for each wheel is not stored. Initialization of linear solenoid valve and calibration undone
C1368/67 - Value of initialization of linear solenoid valve and calibration is not within the brake actuator's standard value. Brake actuator
