Hyundai Santa Cruz: ESC (Electronic Stability Control) System / Front Wheel Speed Sensor

- Components

1. Front wheel speed sensor
2. Front wheel speed sensor connector

1.Loosen the wheel nuts slightly.Raise the vehicle, and make sure it is securely supported.

2.Remove the front wheel and tire.(Refer to Suspension System - "Wheel")

3.Remove the front wheel guard.(Refer to Body - "Front Wheel Guard")

4.Disconnect the front wheel speed sensor connector (A).

5.Loosen the bolt and then disconnect the front wheel speed sensor (A).

Tightening torque :8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 lb-ft)

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.

• Ⅰ low :5.88 - 8.4 mA• Ⅰ HIgh : 11.76 - 16.8 mA• Frequency range : 0 - 2500 HZ

1.Install in the reverse order of removal.
