| I had codes cleared at Auto Zone up till about 2 years ago. They said there was a law suit where they were accused of clearing something that resulted in a dangerous condition and they weren't allowed to clear them any more. If it ain't the guvmint it's the dang amblins chasers.

| Yes def was filled 800km ago it took 600km to acknowledge the fill. I think it has something to do with the urea. ? Maybe? I did not renew my onstar I think that is all a bunch if crapp. Long story why but in short it is undependable here for what I needed.

| Could be the def frozen? I think you get 30 mins or something for the truck to thaw the def tank before it throws a code but with the temps we've had the last week or so I don't think that's long enough, can you warm it up in a shop/garage overnight?

| Maybe? It's been outside. Does the def tank have a 115 volt heater in it? Like the block heater but in the def tank? I know there is a 12 volt heater in the tank maybe it isn't enough when temps approach the -30c mark? I'll know tomorrow it's going into the dealer.

| Just the 12 volt heater I think and at 30 below I think it's too cold to properly thaw before it throws a code. I guess you could add an auxiliary 115volt pan heater if it becomes a problem. You'd hafta install it between the tank and the outter tank cover insulation piece. Let us know what the dealer says

| Well dealer has the truck they'll have it all night and hopefully it'll be fixed tomorrow. I was told the urea tank was frozen solid it needs to defrost They tried to download a new program for the 12v elements to maintain. But couldn't for some reason. They suspected because the tank was frozen. So maybe I'll know more tomorrow.
