PG LabelWheel-based Speed and Distance
PG AcronymWBSD
PG NotesMessage sent by the Tractor ECU on the implement bus on construction and agricultural implements providing to connected systems the current measured wheel-based speed. The message also includes a free-running distance counter, an indication of the direction of travel and the state of the start/stop switch or input.

When the ignition key switch is turned off, both the ECU_PWR and PWR have to be maintained to send this message for an additional 2 s. This is not required when the engine is cranking (starting).
Pgn NotesAccuracies of both wheel-based and ground-based sources can be speed-dependent and degrade at low speeds. Wheel-based information might not be updated at the 100 ms rate at low speeds.
