Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
