How to ID service codes?

Hi,

My eco-diesel has 26k miles and, except for the uConnect, I have thoroughly enjoyed the vehicle. After less than 1k miles since it was at the dealer for its 25k service, my engine light went on. I scrolled through my various displays but can't seem to find out what code I'm throwing? I thought I would find it in my Stored Messages. Is this something that only a dealer knows once they've run a diagnostic tool? I live over 2 hours from a dealer. There was no difference in vehicle performance since the light went on so I'm tempted to continue driving it without taking it in.

Thanks,
Chris

There is no way to view the codes without a tool, that I am aware of. I had to go to advance auto to have them check it. I believe Autozone will read the codes as well, or any other auto type store like this.

Re: How to ID service codes?

You can buy an OBD-II reader on eBay for less than $10, and download a free app. It plugs into the dataport under the dash, below the seeing wheel and a bit to the left.

Unfortunately, if you have a 2014 or early 2015 you may have the flawed cat and EGR valve. Tell the dealer to look up all the TSBs for vehicle and order the parts, and you can leave our there for a week or two after the parts come in.

Good luck!

This. Any vehicle owner should acquire an OBD-II reader. They are dirt cheap now and most codes are common enough that you can Google your vehicle + the code and find a short list of possible causes.

Eh. If you have a fever and go to the doctor, the doc *could* (accurately!) tell you that fever is sometimes caused by cancer or HIV. However, fever can be induced by a variety of relatively innocuous causes... so docs don't lead in with the worst case possibilities.

Moral of the story for Chris: pull the codes with a reader (resist the temptation to erase/clear them!) and then report back here.

Re: How to ID service codes?

Totally agree with your points, however, I'll stick with my remote, information-less, best-guess assumption about the problem, given that many 2014s have had the Cat/EGR problem starting in the low 20k miles, which seems to be a result of the flawed design of the cylinder head (replaced in later model 2014s) and soot build up issues from low quality US fuel.

And, since the dealer is 2 hours away, he should have all of the TSBs taken care of, which include (I think) the cat and EGR valve replacement.

Could also try changing the air filter (see thread) and the fuel filters (which are messy but easy for a non-mechanic) or at least try to drain any water collected in the fuel filter housing (also messy but easy).

How to ID service codes?

SCR/DEF problems were tune and or hardware related isolated to themselves. The cylinder head issue is its own beast. Possibly amplified by the EGR, that's highly debatable.

There is no EGR replacement TSB, it does what it was designed to do just fine. It lowers NOX and fills your motor with carbon. On the SCR front, they'll likely flash your ECM first, send you packing, and then half way home you'll turn around with a MIL and hopefully at that point they'll oblige you with the SCR replacement and you should be good lol.

Well, my anecdotal experience is that I *have* had the check engine light illuminate on my 2014 EcoDiesel, and it wasn't P20EE... it was a false alarm P20E9 & P204F for the SCR system (that never recurred).

There is no TSB for replacing the scr cat in absence of P20EE, and no EGR replacement TSB at all. The cylinder head repair TSB isn't something to enter into lightly (due to the risks of a partial engine rebuild) and isn't even based necessarily on the check engine light.

He should just pull the codes and go from there. It's premature to do anything except to decide which recalls he does *not* want performed (haha, visor wiring and uconnect firmware opt-out, anyone?).

Thanks guys. I'll invest in an OBD-II reader.

Awesome. Just be sure NOT to erase/clear the codes without checking in first. If it is the P20EE issue that kleyp referenced then having the code present is necessary for the dealer to proceed with the repair.

If your check engine light is due to a more innocuous cause then you can clear the code after figuring out what is going on.

Let us know what you get. I need one too, should have bought one long ago.


Anyone out there have a recommendation? I guess if they're just $10 you can't go wrong.

Re: How to ID service codes?

I received my AGT MT-50 OBD2 reader today - purchased from Amazon for $19. The code it is throwing is P1288 - Short Runner Valve Circuit Condition. I have an appointment with the dealer next week.

Thanks,
Chris
