Service bulletin SB 399
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 Service Bulletin informs affected customers that the electronic control unit (ECU), which controls the antilock braking system (ABS) on the trailing (tag) axle, was installed incorrectly at the production plant on coaches equipped with a rear axle steering (RAS) tag axle could result in unnecessary yaw corrections by the electronic stability control (ESC) system at speeds below 20 mph on model year 2011-2013 MCI J4500 model coaches, and that MCI will remedy the affected coaches at no cost to the customers.
