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 02 and 05-C0050 02 and 05
* Ignition ON.
* Ignition voltage is greater than 10 volts.
C0035 18-C0050 18
* Ignition ON.
* Ignition voltage is greater than 10 volts.
* No other wheel speed circuit DTCs are set.
* The brake pedal is not pressed.
* Two or three other wheel speeds are greater than 0 km/h.
C0035 0F-C0050 0F
* Ignition ON.
* Ignition voltage is greater than 10 volts.
* The brake pedal is not pressed.
* A DTC is not set for the other wheel speed circuit on the same axle.
Conditions for Setting the DTC
C0035 02-C0050 02
* A short to ground, open/high resistance is detected on the wheel speed sensor signal circuit.
* Wheel speed sensor power supply is less than 7.6 volts.
C0035 05-C0050 05
A short to voltage, short to ground or an open/high resistance is detected on the signal circuit.
