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
