Right Front Sensor Continuity < 25 MPH

When monitored: Anytime the vehicle is moving <25 mph.

Set condition: The CAB continuously monitors the wheel speed sensor circuits. If a speed sensor signal cuts in and out below 25 mph, this code is set.

Note: If the signal is missing for more than 30 seconds, both the Continuity < 25 MPH and Signal Missing codes will be set.

Possible causes:

> Tonewheel
> Wheel speed sensor contaminated, loose, damaged, etc.
> Wheel speed sensor/tone wheel air gap out of tolerance
