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.



C0035 5A - C0050 5A



Difference between fastest and slowest wheel speed is greater than 50% for 30 seconds.



Action Taken When the DTC Sets



* The EBCM disables the ABS, traction control, and stability control for the duration of the ignition cycle.



* The ABS indicator turns ON.



* The traction control/stability control-active indicator turns ON.



Conditions for Clearing the DTC



* A current DTC clears when the diagnostic runs and passes.



* The EBCM will turn OFF the indicator in the next ignition cycle.



Diagnostic Aids



* Do not use a magnet to clean the encoder ring.



* If 2 or more wheel speed sensors are inoperative, diagnose each wheel speed sensor individually.

Circuit/System Verification



Ignition ON, driving in a straight line at a speed greater than 20 km/h (13 mph), observes the scan tool Wheel Speed Sensor parameters. The



readings should be within 1 mph of each other.



Circuit/System Testing



1. Ignition OFF, disconnect the harness connector at the appropriate B5 wheel speed sensor.



2. Ignition ON, test for greater than 11 V between the signal circuit terminal B and ground.



瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
