C1204 HYUNDAI Description
The Wheel Speed Sensor is the essential component the Anti-Lock Brake System (ABS) ECU uses to calculate vehicle speed and to determine whether wheel lock occurs. For example, a rear-wheel speed signal is used as a reference value, for vehicle speed, in front-wheel drive vehicles, and if a difference between the front and rear wheel speed occurs, then ABS control is performed. The wheel speed sensor generates sinewave signals, based on a magnetic field made by a permanent magnet in the speed sensor when the tone wheel rotates. The ABS ECU monitors the wheel speed sensor signal continuously. This code is set when an abnormal signal due to an air gap problem or an abnormal speed change ratio is detected at the vehicle speed between 10 km/h to 80 km/h(6.2mph to 49.7mph). The warning lamp is turned OFF unless additional faults are detected when the IG KEY has turned ON again, and wheel speed is more than 12 Km/h(7.5mph).
