To diagnose the C1439 code, it typically requires 1.0 hour of labor.

It is common for most auto repair shops to charge between $75 and $150 per hour.
The Skid Control ECU (Brake Actuator Assembly) acquires a steering sensor zero point every time the ignition switch is turned to ON and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores the previous zero point. The steering sensor zero point malfunction warning is canceled by turning the ignition switch off. The Diagnostic Trouble Code (DTC) will be set after the steering sensor zero point calibration is cleared due to, for example, fluctuations in the power source, the steering sensor zero point calibration cannot be obtained for 0.048 seconds of continuous driving.
