Service bulletin TheWrenchDec2020

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The Wrench - If DTCs appear on a new 2018 and newer GL1800, these are likely ABS related and are generated when the factory runs the freshly built unit on a dyno to verify proper engine and transmission operation. These stored codes are easily cleared using MCS, and will not return unless there is a problem related to the front (1-1) or rear (1-3) wheel speed sensors, or there is a CAN communication error (8-7) related to the ABS system.
