Hyundai Ioniq: ESP(Electronic Stability Program) System / Front Wheel Speed Sensor. Repair procedures
1. | Loosen the wheel nuts slightly. Raise the vehicle, and make sure it is securely supported. |
2. | Remove the front wheel and tire (A) from the front hub. Tightening torque : 107.9 - 127.5 N.m (11.0 - 13.0 kgf.m, 79.6 - 94.0 lb-ft) |
•
| Be careful not to damage the hub bolts when removing the front wheel and tire (A). |
|
|
3. | Loosen the bolt and then remove the wheel speed sensor (A). Tightening torque : 7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft) |
|
4. | Loosen the mounting holt and then remove the brake hose from the strut assembly. Tightening torque : 8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 lb-ft) |
|
5. | Remove the front wheel guard. (Refer to Body - "Front Wheel Guard") |
6. | Disconnect the connector after removing the cable bracket mouniting bolt and fixed clip. Tightening torque : 8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 lb-ft) |
|
7. | Installation in the reverse of removal. |
1. | Measure the output voltage between the terminal of the wheel speed sensor and the body ground. •
| In order to protect the wheel speed sensor, when measuring output voltage, a 100Ω resister must be used as shown. |
|
|
2. | Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage as shown below. V_Low : 0.59V - 0.84V V_High : 1.18V - 1.68V Frequency range : 1 - 2,500 Hz |
