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

The Agility Fuel Solutions \(Agility®\) service team identified two fuel system ECU \(electronic control unit\) calibration issues in Blue iQ CNG \(compressed natural gas\) fuel systems for the Cummins® 6.7L engine. Issue 1: Program incompatibility causes throttle response to drop to zero when an attempt is made to operate in economy \(Eco\) mode. Issue 2: ?Liters to Empty? Smart Gauge function is not programmed; at fuel levels less than 5\-10%, zero throttle response results. Agility® is coding a new ECU calibration to remedy these conditions which will be distributed through the Cummins INSITE customer online portal.
