Service bulletin Testman Flashing

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

ZF has prepared two TSBs (separately submitted under 49 C.F.R. § 579.5(b)) regarding: (1) replacement of the ReAX module within the steering column on certain recreational vehicles and transit busses; and (2) a related software reflash. ZF previously offered an interim software solution to address customer field experiences regarding the ReAX system. At that time, ZF provided a guide for upgrading the ReAX module from the then-current 14F level software to the new 14G level software. Although the 14G reflash addressed different performance issues for different customers, a single slide deck was prepared for ZF?s customers explaining the overall reflash procedure. This communication was identified during a review of the current software reflash TSB, which upgrades the existing 14G level software to the most recent 14H level software. Because it had not been previously submitted, in accordance with our process and in an abundance of caution, ZF is reporting this previous communication.
