DTC C1345-51: Linear Solenoid Valve Offset Learning Not Programmed; DTC C1345-54: Linear Solenoid Valve Offset Learning Missing Calibration [11/2020 - ]: Description

The No. 1 skid control ECU (brake booster with master cylinder assembly) stores the individual characteristics of each linear solenoid built into the brake booster with master cylinder assembly. Based on the stored information, the No. 1 skid control ECU (brake booster with master cylinder assembly) calibrates the individual differences and controls systems.

The No. 2 skid control ECU (brake actuator assembly) receives the shift position P signal from the EV control ECU via CAN communication system.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	DTC Output from	Priority	Note
C1345-51	Linear Solenoid Valve Offset Learning Not Programmed	The linear solenoid valve offset learning value is not stored.	Perform linear solenoid valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal. No. 1 skid control ECU (brake booster with master cylinder assembly)	Brake Booster	B	Output ECU: No. 1 skid control ECU (brake booster with master cylinder assembly) HINT: During Dealer Mode, related DTCs are cleared.
C1345-54	Linear Solenoid Valve Offset Learning Missing Calibration	The linear solenoid valve offset learning value cannot be obtained.	Perform linear solenoid valve offset learning and check for DTCs. If no DTCs are output again, the valve is normal. No. 1 skid control ECU (brake booster with master cylinder assembly)	Brake Booster	B	Output ECU: No. 1 skid control ECU (brake booster with master cylinder assembly)
