Service bulletin KTB2607

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

KTM North America, Inc. has identified a deviation that may cause the turn signal flashers to blink at a rate that is faster than normal. To resolve this, an update of the dashboard software is required. This software update solves the possibility of the turn signal flashers blinking too fast, particularly at low ambient temperatures.

The document
