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.

Conditions for Setting the DTC

C0035 06 - C0050 06

A short to voltage, short to ground or open/high resistance on the wheel speed sensor 12 V reference or low reference circuit is detected for 0.14

second.

C0035 0F - C0050 0F

An erratic wheel speed sensor signal is detected for 0.17 second.

C0035 18 - C0050 18

A missing wheel speed sensor signal is detected for 180 seconds.
