Code C1368 Description

The skid control ECU stores and corrects the difference in each individual part such as the stroke sensor, actuator soelnoid, and stroke simulator solenoid. Perform initialization of linear solenoid valve and calibration if these parts are replaced.
The skid control ECU receives shift position P signal from the HV control ECU through CAN communication system.
The DTCs are cancelled when result of linear valve offset learning is normal.
