DTC Information: DTC Detecting Condition

Item		Detecting Condition	Possible Cause
DTC Strategy		Monitor voltage	Poor connector connection Faulty auxiliary battery Faulty motor Faulty IEBU Open in motor circuit
Enable Condition		Normal battery voltage (9 to 16V) Ignition "ON"
Threshold Value	Case 1	If voltage difference between system battery line BAT_A and BAT_B is greater than 4.0V for 100ms System initial mode: BAT_A, BAT_B monitor circuit activate and check failure After system initial: BAT line monitor circuit operation every 5s and check failure during uncontrolled mode
	Case 2	Driving motor relay operating check when the motor relay is ON and OFF Check OK condition Motor voltage does not changed 0.5V for 50ms Motor voltage does not changed 1.0V for 100ms Motoring condition Once after ECU Wake-up (Only ECU Wake-up by door switch) Once before the system termination
	Case 3	Motor initial check Motor relay supply voltage is out of normal range (6.5V to 18.0V) for 100ms Motor relay output voltage is less than 87.5% of supply power for 100ms After initial check Motor relay supply voltage is out of normal range (6.25V to 18.25V) for 700ms Motor relay output voltage is less than (supply power -1.8V) for 400ms * During control 200ms
	Case 4	Initial check- Motor Pre Driver Initialization is not finished in 200ms after system wake-up- Motor Pre Driver Fault is detected by driver internal diagnostic function for 100ms After initial (online monitor) SP communication between motor pre-driver and MCU is failed for 200ms Motor pre-driver fault is detected by driver internal diagnostic function for 50ms Internal temperature of motor pre-driver fault is over then 175°C (347°F) for 50ms
	Case 5	During Motor control mode, request current and actual measured current are kept over 600ms by more than 10A (fault monitor only when the motor position is not changed over than 0.6mm/5ms) When the absolute value of motor request current is less than 100A, if the motor phase current is bigger than 120A (absolute value) for 100ms
	Case 6	Motor position is changed 0.01mm/5ms for 600ms without motor control If the pressure does not reached normally while the motor is running for 600ms [Forward control] request current is more than 115A, if pressure is not reached 80bar [Backward control] request current is less than -100A, if pressure is not reached 150bar If motor position does not changed normally while the motor is running If the current is continuously over 100A during motor position is at both end point (for 0.6s) If Motor position dose not changed with over than 115A motor current (for 5s)
	Case 7	If motor position value is out of normal range (-5 to 40mm) for 600ms If Motor piston initialization is failed
	Case 8	When estimated motor temperature is judged to be high temperature, the motor current is more than 65Ato 84A for 60s 85A to 104A for 45s 105A to 119A for 30s 120A for 15s Under motor over temperature, motor pwm out does not changed for 60s
Warning Lamp	Case 1	IEB
	Case 2	ABS, ESC, IEB, DBC, AVH
	Case 3 to 8	ABS, ESC, IEB, RBS, DBC, AVH
Disable Condition	Case 1	Maintain the ON state of the battery line monitor circuit off ailed line, if failed battery line voltage returns to the normal range for 1.0s, the fault is recovered
	Case 2	Ignition OFF/ON and relay OFF voltage check is normal
	Case 3, 4	Following conditions are all satisfied for 500ms and motor re-initialization finish Motor supply power is in normal range 6.5V to 18.0V Motor control pre-driver initial done without any failure Motor relay output voltage is bigger than 87.5% of supply voltage
	Case 5, 6	Ignition OFF/ON and motor operation is checked normal state once
	Case 7	Ignition OFF/ON and motor piston initial is normally finished
	Case 8	Ignition OFF/ON and motor over temperature status is cleared
