| Main action |
- Monitor the wheel speed sensor signal
|
- Improper installation of wheel speed sensor
- Abnormal rotor and wheel bearing
- Faulty wheel speed sensor
- Faulty ESP (ESC)
|
| Case 1 |
Threshold value |
- When continuous operation of ABS control to one (or more) wheel over 60 seconds is detected.
|
| Diagnosis time |
|
| MIL |
- EBD/ABS/ESP (ESC) warning lamps are activated EPB lamp is not activated
|
| Reset condition |
- After ignition switch turned OFF and back ON, when all wheel speed is normal after driving more than 12 km/h (7.45 MPH).
|
| Case 2 |
Threshold value |
- ESC: A failure is detected when there is a difference of wheel speeds due to air gap or tone wheel failure (missing teeth).
- FL/RL, FR/RR: 6 km/h~12 km/h (3.7 MPH~7.4 MPH)
FL/FR: 10 km/h~16 km/h (6.2 MPH~9.9M PH)
Fault detection time: maximum 20 seconds
- FL/RL, FR/RR: >12 km/h (7.4 MPH)
FL/FR: > 16 km/h (9.9 MPH)
Fault detection time: maximum 10 seconds
- Fault detection time is maximum 80 seconds when spin occurs on front wheel.
- EPB: When two or more wheel speed sensor input signal failures are detected.
|
| MIL |
- Only one wheel failure
: ABS/ESP (ESC) warning lamps are activated
AVH warning lamp is activated, if equipped.
- Two or more wheels failure
: ABS/EBD/ESP (ESC) warning lamps are activated
AVH warning lamp is activated, if equipped.
|
| Reset condition |
- After ignition switch is turned OFF and back ON, when all wheel speed is normal after driving more than 12 km/h (7.45 MPH).
