Nov 20, 2009 · I just bought a 2005 Granite CV713, and my Lightning Bolt light comes on when under load.

Nov 18, 2015 · Recently in my 2012 Pinnacle I had my ABS and my ATC lights plus the lighting bolt illuminate on my dash. The fillowimh code was stored...MID 136 SID 55 FMI 2.

Nov 11, 2019 · Lightning bolt on dash but not the engine light. The problem that I feel is that the truck is not going into gear good first/reverse. It will go in gear with a clunk then seems to work fine. I also can’t switch between n2/n1 while lightning bolt is on. It only stays on for a day or two then goes out and all issues are ok with going into gear.
