2015 258 Rollback. A little down on power. It needed other work done, so I took it to the Hino service center an hour away. They take two weeks, allegedly fix it.
Driving back to the yard, the check engine light came back on.
I pulled the codes with the same scanner I use for my Sprinter Vans, and I got a list of 29 codes, either pending, current, or permanent. I decided to clear everything out and start from scratch... to see what popped up first (since they obviously didn't clear them out). The moment I cleared the codes, DPR Check came on the screen and it was severely de-rated.
I took it back to the Hino service center (three hours away in this operational state).
Two weeks pass, and they "repaired" it, allegedly.
Driving back to the yard, the check engine light came back on again. The driver stated he could barely hit 75 on the interstate, and it started going downhill further once back in town. The next driver stated it could barely reach 45 mph in town.
I pull the codes, and I get P1515, P0299 as current, P1515, P0299 as pending, P026C Pending, and P2201 as Permanent.
I know the first two (turbo underboost and intercooler performance), and dove around inside the engine compartment, where I found evidence of a small boost leak. I cleaned up the connection at the end of the hose and tightened the clamp, hoping to clear that problem. The P2201 is permanent, and never cleared the system the last time I tried clearing the codes.
I put in a new air filter, then went to reset the computer again to see if the boost codes would go away. Ign on, not running... "clear codes." I hear a click, then the DPR CHECK warning came back on the screen and its in limp mode again. P244B appears in the computer before the engine is even started.
How can I get past this problem? Every time I clear the codes, it goes into limp mode under DPR CHECK. I don't have the Hino computer equipment, just standard OBD-II functionality from an iCarsoft MBII scanner (Chinese knockoff for Mercedes).
Today, I am going to pull the cooling stack, clean everything out and verify all the hoses and connections. I am also putting a new fuel filter in it (just standard PM time), then limping it to the International dealer in town that just got a new Hino tech on-board to see what he thinks and if we can just reset the junk and see what happens.
