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.
