Official summary
"Dealer Message - The December 2020 edition of The Wrench publication is now available on iN. 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."
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
