Challenger Posted October 20, 2013 Share Posted October 20, 2013 Lightening bolt is the malfunction lightX is the shut down light. Shutdown light comes on for something that can damage the engine. Coolant temp, coolant level, oil pressure, things like this. Check your coolant level.

Mackpro Posted October 23, 2013 Share Posted October 23, 2013 On most all Macks (except the 2010+) when both lights are on it's low coolant (or bad low coolant sensor) Quote Link to comment https://www.bigmacktrucks.com/topic/33197-lightning-and-x-symbol-on-dash/#findComment-213016 Share on other sites More sharing options...
Mack2004 Posted December 9, 2022 Share Posted December 9, 2022 My circle with an X popped on for half a second then went out. Never came back on. Coolant level is fine and everything else seems to be normal. Could it have been a fluke? No bolt light on and no codes stored.

Joey Mack Posted December 9, 2022 Share Posted December 9, 2022 Have you looked into this any further.. The 'Shutdown' light can be serious. What other symptoms are you having? It is important that you post the Make/ Model/ Year/ Engine series/ Tranny Model...
