Joel Up Front Posted May 9, 2011 Share #1 Posted May 9, 2011 I know about the brake hissing being the ABS self-diagnostic, but what about that little warbling before the bus actually starts up? And before you ask, yes, the back of this bus doesn't have an Long Island Bus decal or the numbers like the back of every other NG does. It seems to me like they used the side decals just so they could have a number on every side. NG #1793 is also like that. Link to comment Share on other sites More sharing options...
Fresh Pond Posted May 9, 2011 Share #2 Posted May 9, 2011 The beeps you hear is the system checking itself The hissing you hear is the ABS checking itself (as you said) The "warbling" you're referring to is the engine turning over to start...its like starting a car Link to comment Share on other sites More sharing options...
