    No issues on flat land, unfortunately we are west of flagstaff on I-40( not flat) temperature gauge rises while going uphill, ECU maintenance required comes on, fan kicks on, and then stop engine fault, fan shuts off, truck stops. ONLY uphill! Help please....

    Oh, and it will start right back up every time, run fine until we reach the next incline

    Did you check the engine diagnostic and see what fault code it's giving you?

    Are you low on coolant?

    Coolant level is good, the fan is not running long enough to cool it down to the 170-180 degree mark I have a code for a def sensor but my def has been deleted....PPID 278 FMI 9 I’ve had the DEF deleted for over 6 months no issues, until now. but why would it be fine on flat ground? literally it doesn’t pop up until I’m on a steep incline and the engine temperature gets to high. My fan is not kicking on properly

    might have not flashed the ecu correctly when deleting the def modules from the ecu, or was that not done?
