Normal Operation And Fault Conditions
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2021 Lincoln Corsair, 2021 Ford Transit-350 HD, 2021 Ford Transit-350, 2021 Ford Transit-250, and 2021 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.
Active wheel speed sensors generate a voltage signal proportional to wheel speed which is sent to the ABS module. Each wheel speed sensor is connected to the ABS module through 2 wires and a connector at each wheel speed sensor. The 2 circuits provide both sensor power and sensor signal return.
PPT M ABS MODULE DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1A95:01 | Wheel Speed Sensor: General Circuit/Electrical Failure | Sets when the ABS module detects the followingconditions on 1 or more wheel speed sensor circuits; opencircuit, short to voltage, short to ground. Faults with multiplewheel speed sensors also causes this DTC to set. |
| C0031:01 | Left Front Wheel Speed Sensor: General Electrical Failure | Sets when the wheel speed signal continuously exceeds a specified threshold or is operating outside of the allowable range. |
| C0034:01 | Right Front Wheel Speed Sensor: General Electrical Failure | Sets when the wheel speed signal continuously exceeds a specified threshold or is operating outside of the allowable range. |
