# Service bulletin SB 394

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 wheelchair lift threshold warning system \(TWS\) function requires improvement on model year 2012\-2013 MCI J4500 model coaches equipped with the Actia multiplex system. The threshold warning system as currently installed will beep, but will not continuously beep when the wheelchair lift platform is below the cabin floor and the acoustic sensors detect a moving person and/or stationary object in the door way of the designated threshold area with the wheelchair lift cabin door open, and that MCI will remedy the affected coaches at no cost to the customers.
