# Service bulletin MA\-WI\-001

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 current M/MA software was designed with the pump output for wire 40 and wire 41 backwards. Because of this wiring harness design, the gear pump and vane pump configurations cannot be controlled in the same manner. Software version 8.1.18 or later corrects the programming issue.
