Bulletin 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.
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.
