# Service bulletin PN668

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.

- Type: Service bulletin
- NHTSA id: 10152387
- Published by NHTSA: 2018\-12\-17

## NHTSA's summary

Notice that the programing of the IH Daimond Logic chassis controller did not provide two speed operation. It does not increase the engine speed \(about 400 rpm\) above the torque lock up speed to provide maximum pump flow. Four units remain to be reprogrammed at their next maintenance inteval.
