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.
