Code P15FD 2014 GMC Sierra Description

The wheel speeds are detected by active wheel speed sensors. Each wheel speed sensor receives a 12 V reference voltage from the Electronic Brake Control Module (EBCM) and provides an alternating current square wave signal to the EBCM. As the wheel spins, the EBCM uses the frequency of the square wave signal to calculate the wheel speed. The EBCM sends the wheel speed information as a high-speed Controller Area Network (CAN) serial data message.
The Diagnostic Trouble Code (DTC) will be set when a supervised periodic message that includes the wheel speed serial data has not been received.
