Diagnostic Fault Information



Circuit/System Description



The wheel speeds are detected by active wheel speed sensors and encoder rings. The encoder ring consists of permanent magnets. Each wheel



speed sensor receives 12 V reference voltages from the electronic brake control module (EBCM). The wheel speed sensor produces changing



current between 7-14 mA on the EBCM signal circuit. As the wheel spins, the EBCM uses the frequency of the square wave signal to calculate the



actual wheel speed.
