Diagnostic Fault Information

Circuit/System Description

The wheel speed sensor receives ignition voltage from the electronic brake control module (EBCM) and provides a DC square wave signal back to

the module. As the wheel spins, the EBCM uses the frequency of the square wave signal to calculate the wheel speed.

Conditions for Running the DTC

C0035 00-C0050 00

* Ignition ON.

* Ignition voltage is greater than 9.5 volts.
