What's the mercedes fault code c1401?

The Mercedes fault code c1401 means there is a front right wheel speed sensor malfunction. Since the wheel speed sensor also monitors the anti-lock braking system on Your car, it's common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means You'll have to replace the wheel speed sensor. Drivers across the US would be prone to multiple speeding tickets without the important assistance of the wheel speed sensor. This component, which is also referred to as an ABS sensor, is attached to the hub of a drive tire and is responsible for monitoring multiple vehicle functions such as traction control, anti-lock braking systems, and obviously, the vehicles speed.
