Service bulletin 2018-1048

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

E-ONE has identified that a large number of DEF tank senders that have been returned for evaluation have been diagnosed as no fault found from the manufacturer. In an effort to minimize this in the future, we are sending this bulletin along with troubleshooting steps for your technicians to use when you receive customer complaints related to DEF tank gauge level issues.
