Code C1211 KIA 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 there is no wheel speed signal within 10ms to 20ms at a vehicle speed > 43.2 km/h (26.8 mph) or a deviation between sensors exceed the threshold or one or two wheels are at 2.75 km/h (1.7 mph) while the vehicle speed is at 12 km/h (7.5 mph). 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 (7.5 mph).
