Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the C1200 Hyundai code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
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.
