# Service bulletin M011460900

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 new software corrects an issue with false \-7 diagnostic codes for fuel injectors not responding causing unneeded downtime. The Fuel System Verification Test calibrations have been updated and an improved signal filtering algorithm added to capture the correct valve responses. These improvements will provide optimal fuel injector performance.
