If the sensor signal is out of the specified range for 140msec, the HECU determines that the circuit is open/short, and sets this code.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Current Monitoring | 1. Open or short of Wheel speed sensor circuit (RR) 2. Faulty Wheel speed sensor(RR) |
Enable Conditions |
•
When the sensor signal current is continuously out of the specified range of 4 mA ± 10% ~ 60 mA ± 10% for 0.14sec.
•
When the leakage current of wheel speed sensor is above specific current longer than 0.14sec. | |
Fail Safe |
•
One wheel speed sensor fault - Inhibit the ABS/ESP(ESC)/DBC/AVH control, allow the EBD control
•
More than 2 wheel speed sensor fault - All functions are inhibited | |
MIL |
•
One wheel speed sensor fault - The ABS/ESP(ESC)/DBC warning lamps are activated. The AVH warning lmap is activated in case of the vehicle equipped with AVH.
•
More than 2 wheel speed sensor fault - The EBD/ABS/ESP(ESC)/DBC warning lamps are activated. The AVH warning lmap is activated in case of the vehicle equipped with AVH. | |
Reset Condition |
•
Normal after IG turned on again |
