I cleared the codes and they haven't returned, though I haven't driven the truck much. I am now getting a P0600 code which after reading about it is a pretty non specific code. And I am still perplexed that my CEL is not on. I need to pull the cluster and see if someone has removed the bulb. Is the bulb even removable?

Do you see the CEL when you turn the key but don't start the engine?
The bulb can't be removed, but people put black tape over them or break them off the circuit board.
