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.
Conditions for Running the DTC
C0035 06 - C0050 06
Ignition ON
C0035 0F - C0050 0F
* Ignition ON
* Vehicle speed is greater than 35 km/h (22 mph)
C0035 18 - C0050 18
* Ignition ON
* Vehicle speed is greater than 10 km/h (6 mph)
C0035 5A - C0050 5A
* Ignition ON
* Vehicle speed is greater than 20 km/h (13 mph)
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.
