General Information: DTC Detecting Condition

DTC DETECTING CONDITION

Item		Detecting Condition	Possible Cause
DTC Strategy		Voltage monitoring	Open or short of Wheel speed sensor circuit (FL) Faulty Wheel speed sensor (FL)
Case 1	Monitoring Period	Once after power up.
Case 1	Enable Conditions	Shorts between WSS lines and shorts to UZ can be detected by switching single WSS channels in sequence. If there is an error after end of test, a failure is recognized. NOTE: In case of a WSS power line short to V_batt, this FSA test will detect an under voltage failure. (ABS only) * FSA test: fail save circuit test * UZ: Ignition Voltage
Case 2	Monitoring Period	Continuous
Case 2	Enable Conditions	When the sensor current levels are out of permissible range (LOW: 7mA, HIGH: 14mA) for 200ms.
Fail-Safe		Sensor failure outside of the ABS control cycle 1~2 wheel failure Only the ABS/ESC functions are inhibited. The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated. More than 3 wheels failure The ABS/EBD/ESC functions are inhibited. The ABS/EBD/ESC warning lamps are activated. Sensor failure inside the ABS control cycle 1~2 wheel failure The ABS/ESC functions are inhibited after end of control. The ABS/ESC warning lamps are activated and the EBD warning lamp is not activated. More than 3 wheels failure The ABS/EBD/ESC functions are inhibited. The ABS/EBD/ESC warning lamps are activated. * Control of the corresponding wheel is no longer possible. If a sensor fault occurs on a front wheel, pressure is increased; on a rear wheel, pressure is decreased.
