hatcity Posted August 15, 2010 Share Posted August 15, 2010 Red X is telling you to shut 'er down.Lightning bolt is telling you electrical problem.With key on (engine off) press and hold cruise control button. Watch and count flashes on dash.That will give the code for the problem. Sometimes its a fuse, sometimes worse. 1 Quote Success is only a stones throw away.................................................................for a Palestinian Link to comment https://www.bigmacktrucks.com/topic/15291-x-with-circle-around-and-ligthning-warning/#findComment-61675 Share on other sites More sharing options...
joes mack Posted August 15, 2010 Share Posted August 15, 2010 that is the engine shutdown light it might be overheating, low or lost oil press low coolant level belts missing or sliping bad or it could be bad sensors or guages . any thing is poss with these newer trucks. most times when the engine shutdown light comes on on our trucks its the fan belts or the coolant levels that are the problem. but we have seen the electrical system cause havoc with these trucks also . joe Quote Link to comment https://www.bigmacktrucks.com/topic/15291-x-with-circle-around-and-ligthning-warning/#findComment-61677 Share on other sites More sharing options...
Mackpro Posted August 16, 2010 Share Posted August 16, 2010 I have an X with circle around it and ligthning bolt showing on the dash coul someone help me out on what that indicates i drive a Mack granite concrete mixer 2005The only time both "Red X shutdown" light and "yellow lighting bolt EML" come on at the same is when there is a low coolant fault. ( except on the DPF equipped MP7 and MP8 engines)Check the coolant level and if it's full it could be a coolant level sensor failure. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/15291-x-with-circle-around-and-ligthning-warning/#findComment-61709 Share on other sites More sharing options...
