DTC Information: DTC Detecting Condition

Item		Detecting Condition	Possible cause
Case 1	DTC Strategy	Valve relay malfunction monitoring (Solenoid valve coil open)	Damaged or poor connector connection Faulty IBAU
	Enable Conditions	Valve relay "ON"/Solenoid valve "OFF" ABS valve: Voltage of vale is less than 2.0V for 0.06 sec. AHB valve: Voltage difference in relay and valve is over 5V for 1 sec. Valve relay "ON"/Solenoid valve "ON" AHB valve: Target current of valve is more than 1A for 1 sec and actual current is less than 20% of target current
	MIL	The EBD/RBS/ABS//ESP (ESC)/DBC warning lamps are activated. The AVH warning lamp is activated in case of the vehicle equipped with AVH.
Case 2	DTC Strategy	Valve relay malfunction monitoring (Solenoid valve coil short)
	Enable Conditions	Valve relay "ON"/Solenoid valve "ON" ABS valve: Current of valve is over 8.5±2.5A for 0.06 seconds. AHB valve: Voltage difference in valve relay and AHB valve is less than 0.8V.
	MIL	The EBD/RBS/ABS//ESP (ESC)/DBC warning lamps are activated. The AVH warning lamp is activated in case of the vehicle equipped with AVH.
Reset condition		Turn ignition switch off and on.
Remarks		If AHB valve is malfunctioned, AHB control is not possible and the buzzer is working.
