This bulletin informs dealers that Harley-Davidson has identified a Instrument Module (IM) software error on 2021 Pan America and Sportster S models. When the internal IM temperature is below freezing 0 °C (32 °F), the IM display may generate an error message. Shortly thereafter, it goes blank until the next ignition cycle when the IM temperature is above freezing. If the warning is ignored and the vehicle is operated, the speedometer and neutral indicator would not be visible as required by FMVSS No. 123.
