Need help understanding "New" codes in Paccar engine.

Your point about waiting till this "new technology" has been on the market for 5 years used to make sense. I bought a bridge Cat 10 years ago and regretted it from day one. But todays technology changes so fast, if you wait a few years, you will be dealing with a whole new system. I know this as a fact, I waited when my friends bought trucks in '08... The new DPF's were destroying engines. A few other friends bought Cummins in 2011 and '12, sinking liners, after treatment issues... I then waited till the new DEF technology was around for a couple of years... Guess what, its all changing again... I was assured by Paccar Reps that they would stand by their product if I took a chance on them. For the most part they have been very diligent about trying but I can't wait for them to get it figured out so I am dealing with it in another way. My recommendation is to go with Cummins and deal with the issues associated with them, they have very serious engine and after treatment issues. But at least they can diagnose and repair them, that is more than Paccar can do. You go ahead and wait till 5 years after this stuff is all resolved, I can't, I make my living in California. Your truck could have 5 million miles on it by the time this stuff is resolved so you better be taking good care of it.

 

UPDATE: I finally found a guy who said "Oh, I know what the problem is". Took 30 minutes to find the "Can Bus 2 Fault". A loose plug in one of the CAN's under the truck. He plugged into the dash, I crawled under the truck, grabbed the cluster of wires, as soon as I touched it he said "Thats it"! The laptop went crazy flashing codes. He's fixing that harness now.
Anyone have any Idea what I should do about Rush truck center and Paccar bilking me out of $10,000 over 4 months? I begged them to check "CAN bus 2" 4 months ago but they treated me like an idiot for suggesting they weren't looking in the right place.

 

I have NEVER heard anybody say "Rush did a good job"... How are they still in business? I understand Paccar and Peterbilt paying them to throw parts at new trucks but I can't imagine how they can make enough doing that and not need older trucks with cash paying customers.... Oh, wait... Yeah, $130 an hour to throw a nonstop barrage of parts at the thousands of junk trucks being spit out by Peterbilt, Yeah, that does sound pretty lucrative.

 

Still fighting CAN - BUS issues, ECM issues, and now EGR problems. No end in sight, Ive had a few different chassis electrical/computer gurus try but they all say the same thing.... Should not have bought a Paccar.
Its a great engine internally, but the electronics make it unusable now. I can't load the truck because I can't deliver loads with it, G.E. Capitol does not want it back and say they are willing to "work with me" but I told them, it can not be fixed so come and get it now or in six months, either way it doesn't matter.
For Sale: 2013 Peterbilt 388 - Pay no attention to all the dash lights and dinging bells.... Runs great (for about 400 miles then you'll need to stop at a Paccar shop).

 

The problem is (as always) big money players like Swift, Knight, and Werner love to tell whoever asks that it all works just fine. They are the ones who funded the push for it, just like E-logs and anything else that makes it harder for small operations to compete.
Last year I had a chat with my Congressman about this problem and he was honest enough to tell me that not enough people care about our problems to start upsetting donors from big trucking companies.
Its up to us to do our homework and find the healthiest horse in the glue factory, every engine and after treatment system has problems but some have less than others. Unfortunately for me, I was a third generation Peterbilt guy and believed their lies about the Paccar engine. What I know now is that MaxForce is the worst and Paccar is not much better. Anyone considering a 2012 to 2015 truck should stick with Cummins or Volvo. Yeah, they have serious issues but you can fix them and get back on the road, thats not the case with Paccar.
