I was trying to clear some DTC codes before I take my truck in for work. Evertytime I cleared via "Shift+F11" it looked as though it cleared but then read te same codes back again. Any suggestions?

What codes are you getting?? If they are ERG codes, you may need to set some parameters that will effectively shut it down.

Codes are C0035, C0040, C0055, C0245...U1000, U1064

The code could be a sign of a problem. Clearing the code doesn't clear the problem. And after it's cleared then comes back.
I'd think you would want to find out why there coming back.

if codes are cleared and come right back, there is a reason. Need to get it checked out and figure out why the codes keep reseting.
