Code C0245 2014 GMC Sierra Description

The C0245 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a Wheel Speed Sensor Frequency Malfunction. This code is typically triggered when the electronic control module (ECM) detects that the frequency of the wheel speed sensor signals is not within the expected range. The wheel speed sensors are crucial components of the vehicle's anti-lock braking system (ABS) and traction control system, as they provide vital information about the speed of each wheel to the ECM.
