Circuit/System Description
The wheel speed sensor receives a 12-volt power supply
voltage from the electronic brake control module
(EBCM) and provides an output signal to the EBCM. As
the wheel spins, the wheel speed sensor sends the
EBCM a DC square wave signal. The EBCM uses the
frequency of the square wave signal to calculate the
wheel speed.
Conditions for Running the DTC
C0035 - C0050 00
• The ignition is ON.
• Ignition voltage is greater than 9.5 volts.
C0035 - C0050 0F
• The ignition is ON.
• Ignition voltage is greater than 9.5 volts.
• The brake pedal is not pressed.
• A DTC is not set for the other wheel speed circuit on
the same axle.
C0035 - C0050 18
• The ignition is ON.
• Ignition voltage is greater than 9.5 volts.
• The brake pedal is not pressed.
• No other wheel speed circuit DTCs are set.
• At least 2 other wheel speeds are not 0 km/h.

Conditions for Setting the DTC
C0035 - C0050 00
• An open is detected on the wheel speed sensor signal
circuit.
• A short to ground is detected on the wheel speed
sensor signal circuit.
• A short to voltage is detected on the wheel speed
sensor signal circuit.
C0035 - C0050 0F
The EBCM detects a rapid variation in the wheel speed.
The wheel speed changes by 20 km/h (12 mph) or more
in 0.01 second. The change must occur 3 times with no
more than 0.2 second between occurrences.
C0035 - C0050 18
• One wheel speed is 2km/h (1.2 mph).
• The remaining wheel speeds are greater than 10 km/h
(6.2 mph).
• The difference between the remaining wheel speeds
is less than 8 km/h (5 mph) from each other for 180
seconds.
OR
• The 2 wheel speed sensor inputs are 0 and DTCs are
set.
• The 2 suspect wheel speeds equal zero for 6
seconds.
• The other wheel speeds are greater than 15 km/h (10
mph).
