Diesel Exhaust Fluid issue hopefully resolved

13redwings19 · 01-17-2011, 03:54 PM

My DEF system never did read how much DEF I actually had in the tank. Hopefully got it fixed today and I did learn a few new things that GM sent out to the mechanics very recently. This could be stuff you already know, but I doesn't hurt to try to give some facts.

The new GM suggestion for when to add DEF is when the 1st warning light is activated and your DIC reads Exhaust Fluid Range: 1000. They suggest to add 3.5 gallons at that time. You must drive the truck for a while to get the system to read the level again. If the DIC doesn't clear then after you shut the truck off for 5 minutes it SHOULD clear the system.

If your truck does what mine did and what quite a few others have done, the system won't read the change and your range will continue to fall. You must get it fixed or you will lose speed and power when you get under 75 miles left. The mechanic must drain the tank and put in a new calibration system. The new system came out 1/13/2011 is what the papers showed.

Hopefully your new truck won't run into the DEF issues. I can't really answer any questions because I'm no mechanic. I'm just trying to spread word on what I was told and what information I saw.

have you had any problems since... I have an identical truck but i def in before the warning and now im having more major problems with mine....

During 2011 there were multiple releases of the programming associated with PIP4864, and then a recall (for 2011 trucks) in the fall of 2011.

If you have a version from 13 Jan 2011, you are probably not yet done with this issue.

redwngr, is yours still 'intact'? if so have the updates taken care of the issues (if u had any to start with) ?

Yes its' intact.

PIP4864 rev D was done because it had the classic issue of not resetting after a def refill. 4 or 5 weeks later (and 500 miles from home) it decided it needed fluid again, but would only take less than a quart, and would not reset. Found a dealer, and because of knowledge from this site, was able to work with service writer to keep researching in his computer and find PIP4864. (He wanted to follow a procedure that was for a different problem ). Anyway, he agreed PIP4864 was the correct thing to do, and the truck has been trouble free since.

I've had zero troubles since PIP4864 rev F was applied in late spring 2011. I had the 'recall' programming done late in the fall.

The truck has just over 30,000 miles.

30,000 sounds like a good enough test drive

I am now at 21000 miles and I have not had an issue since my original post

I think that I need to take mine in to get checked. Mine did give me the low fluid warning. Then soon there after I get the "Engine Power Reduced" warning. Now the truck runs a little funny. Doesn't seem to have the power it use to have..
