I did not mention it, but I swapped the display first. same thing, exclamation red light, no hour meter, just a small circle. Swapped FNR switch, same thing, cut out drive. The coolant level sensor was busted, i jumpered it. Now that the truck wont recognize respond to the seat switch open, i suspect the ECM. After cleaning the connections, the truck changed and now runs with no codes or drive shut down.
Wife is tugging at me, new years party awaits>>>>
Happy new year all!
