I have one of those little IC buses low profile . It has the 365 V8 with an allison hydaulic brakes . Driver came off her run yesterday and shut her bus off to do her post trip . Went to start the us to put it away and nothing . Said during run the bus had a hicup but stayed running . So I grabbed my laptop think it was transmision . Couldn't read the computer . So I checked the engine and same thing wouldn't connect so no readings . Where should I look and would both show no signs of life ? When I turn the key I just get a click like te bus is in gear . Thanks for any help
check for 60 ohms at connector plug on the 1939 data link might be bad power to a pdm which houses the fuses and/or relays for drive train (loose connections or bad) sounds like data link issue where the engine is not seeing neutral signal plus you can't hook up to either

2006 should have the two power harnesses ( one is grounds) they follow drivers side frame then come up fire wall and feed the fire wall relays , I 've found issues with those harnesses alot of time

Now I found something really wierd . We pushed this bus into the shop. When the guy steering the bus tried to open the service door the stop paddle and lights came on . The only way to turn them off was to sut the door . This was done with the key on . So I tried the amber lights and they don't work . I wouldn't have thought everything was tied to the ECM ? Anybody have any ideas ?
