Thomas Saf t Liner, check air intake

[nachosforjoe]

So I turned my bus on today and the check engine light, check air intake light, and stop engine light all went on. As well as an alarm by the driver. I am wondering if I have an actual issue or if I need to let it run for a bit in order to build air pressure up. Did notice my air pressure was below the red line on the dashboard. It also took a bit for the bus to turn over. Havent turned it on in over a week so that might be the delay. It was raining out so I didnt spend much time investigating it, but figured I should at least start to poke around online and see what I can find.

Thanks in advance

Was bus running with all these lights on? if so YES there is a problem

IF NO, this normal to check bulbs for working condition

check engine, could be related to emmisions or??? depending on model

check air intake, could be a stopped up air filter that needs replaced

stop engine light, shouldn't be on when engine running (need to figure out what controls this, maybe it's an oil pressure switch)

the buzzer should be low air pressure, and yes bus needs to be run for a few mintues to build up pressure (google air brake testing on youtube)

PLEASE FAMILIARIZE YOURSELF WITH SAFE OPERATING CONDITIONS OF AIR BRAKES
PLENTY OF INFO ONLINE
