Code C0245 Buick Description

The wheel speeds are detected by active wheel speed sensors. Each wheel speed sensor receives ignition voltage from the Electronic Brake Control Module (EBCM) and provides an alternating current square wave signal to the Electronic Brake Control Module. As the wheel spins, the Electronic Brake Control Module uses the frequency of the square wave signal to calculate the wheel speed. The Diagnostic Trouble Code (DTC) will be set when the wheel speed difference between one wheel and the others is greater than 20 percent.
