DTC C1345/66: Linear Solenoid Valve Offset Learning Undone; DTC C1368/67: Linear Solenoid Valve Offset Malfunction [10/2015 - ]: Description

The skid control ECU (brake booster with master cylinder assembly) stores and corrects the individual differences in the brake pedal stroke sensor assembly, actuator solenoids, and stroke simulator solenoid. Perform initialization and calibration of the linear solenoid valve if any of these parts is replaced.

The skid control ECU (brake booster with master cylinder assembly) receives the shift position P signal from the hybrid vehicle control ECU assembly through the CAN communication system.

These DTCs are cleared when the linear valve offset learning results are normal.

DTC No.	INF Code	DTC Detection Condition	Trouble Area
C1345/66	-	Linear valve offset learning undone.	Perform linear valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal.
C1368/67	-	Offset learned value out of specification.	Perform linear valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal. Brake actuator (Brake booster with master cylinder assembly)
