What Does the C1209 KIA Code Mean?

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 circuit continuously. A direct current is supplied in the wheel-speed sensor by a power source in the input amplifier of the control unit. If the WSS circuit is broken, that case, a fault is detected by detecting an abnormal input current. HECU cuts off the voltage supply to the wheel sensor channel which had a fault and prevents the vehicle's damage due to the super-heated harness. If one or more defects have detected, the Diagnostic Trouble Code (DTC) code of defected wheel will be stored. Mutual short between sensors is detected by executing self-diagnosis successively at the corresponding wheel when ignition ON. The warning lamp is turned OFF unless additional faults are detected when the IG KEY has turned ON again.
