# Service bulletin SB 398B

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: 10119151
- Published by NHTSA: 2017\-10\-15
- Manufacturer's number: SB 398B
- Manufacturer's date: 2013\-08\-15
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

This Service Bulletin informs affected customers that due to the Actia's module internal circuit characteristic the potential may exist in which both the high side and low side output of power management module \(PMM\)1 may be active at the same time for a very brief time. This may result in an electrical short on the low side output and intermittent loss of the ignition signal on model year 2010\-2012 MCI D model coaches, and that MCI will remedy the affected coaches at no cost to the customers.
