06 LBZ 2 days ago had that pop up on DIC, read in owners manual that it has to do with coolant, and temp. Engine was cold as it was just started and warmer up, coolant level is right on level. Had no power when I started out and went and shifted to manual trans, went thru gears and had power.??? tried to delete info on DIC and was not able to. Yesterday she ran normal and display is clear on DIC. My ques. is might that reading also have something else beside coolant I need to be concern with? is there a different way to delete it from DIC, or it will clear itself? Thank you for any info on this. I'm still learning the duramax world. Chris.
