Normal Operation and Fault Conditions
REFER to WHEEL SPEED SENSOR .
When the ignition is set to ON, the Anti-Lock Brake System (ABS) module carries out a self-test by sending a reference voltage through the wheel speed sensors and their circuitry.
DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0031:01 | Left Front Wheel Speed Sensor: General Electrical Failure | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if any wheel speed sensor signal current is below 4.5 mA or above 20 mA for longer than 140 milliseconds, or if either sensor circuit is shorted to ground or battery voltage. |
| C0031:19 | Left Front Wheel Speed Sensor: Circuit Current Above Threshold | |
| C0034:01 | Right Front Wheel Speed Sensor: General Electrical Failure | |
| C0034:19 | Right Front Wheel Speed Sensor: Circuit Current Above Threshold |
