DETECTION
These faults are detected when the vehicle speed is above 8 MPH.

DESCRIPTION
These are wheel speed sensor faults. They are set when the CAB fails to detect a signal from one or more sensors. The missing sensor signal (or signals) must be missing for more than three seconds, or, when both rear wheel sensors are missing, 30 seconds. The second case prevents false faults caused by excess front wheel spin, such as happens with a snowbound vehicle.)
