Service bulletin I-15-01-01

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

Indian Motorcycle has released a software update for some 2014-2015 Indian Classic / Vintage / Chieftain motorcycles to address customer concerns with Brake-Throttle Override (BTO) functionality. The BTO system will temporarily close the throttle plate and, in some cases, illuminate the Malfunction Indicator Lamp (MIL) if the brakes and throttle are applied at the same time while the vehicle is in motion. While this operation is normal, it is not always compatible with each individual riding style.
