Service bulletin C1858A

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

This In-Shop Campaign is being issued to address sensor related fault codes 1866, 3383 and 3228 on certain ISX15 engines installed in Kenworth T680 and T880 chassis. Certified repair locations are authorized to change the mounting of the Original Equipment Manufacturer (OEM) wire harness per the instructions in this bulletin on certain engines. This action may be completed anytime the unit is in for maintenance or repairs, with certain restrictions on reimbursement. This is a revision to a previously submitted communication.
