Code U113C Description

The U113C diagnostic trouble code (DTC) refers to "Lost Wheel Speed Messages," indicating a communication issue between the vehicle's anti-lock braking system (ABS) module and the wheel speed sensors. This code typically means that the ABS module is not receiving the necessary data from one or more wheel speed sensors, which can impact the vehicle's ability to accurately monitor wheel speeds and adjust braking accordingly. This could compromise the effectiveness of the ABS system, potentially leading to longer stopping distances, reduced traction control functionality, and compromised stability during emergency maneuvers.
