# Service bulletin ISA\-20\-03 R02

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 identified a potential calibration issue affecting some 111/116 c.i. motorcycles. In some instances, the throttle twist grip and Electronic Throttle Control \(ETC\) position signals do not align with the predicted position within the ECM and set a P1530 fault \(throttle plausibility\). When active, the P1530 fault causes the motorcycle to operate in a reduced power \(limp\) mode.
