DD-15

That is the bad thing about computers, they print out data. You really want to get a copy of the fault history it will give you the engine serial number and the time the low pressure started and stopped and the lowest pressure it went to. It gives you a very good idea of what happened, and how long the problem has been going on, it will give you the first and last code times. Day date and hour, and minute
You also want a printout of the parameters to see if the unit was set for shut down or just to turn on a light. that printout will also have the engine serial number. Check the paper work, request a meeting with the regional representative, be nice and ask if there is anything he can do for you. If you do not ask there is no chance.

 

Last time I checked, I thought if the ECM detected low oil pressure or low coolant the engine would shut down.

 

Low oil pressure, high oil temperature, high water temperature and low coolant levels are a programmable parameter and can be changed to just turn on the light, some had an override switch that would give you 15 seconds, every time you tripped the switch to get the unit to a safe place.

 

All the dealer showed me was a single page that shows there was almost 3 hours of pressure under 5 psi and they claim there is no way of knowing when the low pressure happened. My argument is that the light didn't come on until the engine blew (and then it did instantly), and the gauge on the dash NEVER went under 12 and certainly not to 5 like they claim. My argument is also that the low pressure most likely happened before the base warranty was up. All of these codes you are talking about: are you sure they can do it? It's a 09 Pete with a cummins. Any help is REALLY appreciated from anyone who can. When I call the dealership they treat me like I punched their pet cat in the face but in reality all I want is for Cummins to come good on this motor. I would have thought the 2 trucks and the trailer I have bought from them would get me some level of service but there appears to be none at all.

If any of you guys are Peterbilt or Cummins mechanics and can verify that I can really get more detailed info from the truck please PM me or respond. I can't even sleep at night now over this whole garbage.

 

What you want them to do is print out a complete fault code history, every page will have the engine serial number on it. That code will have the first and last code in detail. It will tell you the throttle position the water temperature, the time and date the first code came up, and the amount of seconds the code was active, a long list. same for the last code. You want to Phone and ask them for the complete print out, ECM history. You really do want to call the warranty representative and tell him what they are telling you, and your request.
I realise you will find it hard to believe but, they could be lying to you.

 

that is what I am starting to fear. This really sucks. I've been such a huge fan of my Cummins motors and this really leaves a bad taste in my mouth. Thanks for the help.

 

I bought a 2011 Western Star last October with the DD15 and urea.I haul logs to 60,000 kg.The engine is easy to service,it's quiet and the jake is great.It's a 560 hp. and not a real power house,but what is? I haul with guys who have the new 565 cummins and they're real dissappointed in the power.Both engine are good on fuel but urea needs to be added also.The cummins seems to still need more bugs worked out as they still have their problems.I dont know if theres a place that works a truck as hard as our industry and so far these engines are holding their own.

 

The DD15 is new down here with only a handful on the road, so I am very interested to hear how they perform, AND the electrical problems that I may have to deal with in the future. Due to our emission rules you can still get new DDEC6 EGR non DPF S60's at a better price.
I have been working on DDEC engines since the first 8V92 DDECI's arrived here in the '80s. They were a steep learning curve and the progression through to DDECV kept us on our toes. I consider the DDECIV non EGR S60 to be the cream of the electronic engines. We missed out on the DDECV EGR truck engines and only have a few non EGR industrials. These engines are lucky, "they don't have to eat their own ####".
In my opinion, DDECVI is not a genuine DDEC system. It is a German system called TEMIC, that has been adapted to look like DDEC. Getting to grips with it is like going back to when DDECI arrived.
I was horrified when I first saw the wiring looms on a DDECVI S60. The wires are very thin, and run untaped through convoluted plastic sleeving. This in my opinion is a recipe for disaster. Detroit have been making engine looms for nearly thirty years. All the lessons they have learned have been thrown out the window, and the only reason I can think of is price.
Are you guys having problems with engine looms, or am I just being overly sceptical?

 

150000 kms I have had a complete engine wiring harness replaced, turbo, lots of sensors, throttle intake valve and an ECM. Truck still runs like crap when its regenning. I am getting crazy good fuel mileage just got home haulked a light load (20,000 lbs) east from Toronto and got 7.8 per US gallon. And didn't spare the ponys. I wish they could get the regen issue sorted. The truck is quiet, rides good and gets great fuel mileage. It out pulls any prostar. Mine is DD15 530hp 1850 with 22.5 tires and 3:55 rears.

 

Is it possible for the dealer to erase or delete those fault codes?
