Did you get to the bottom of this? Sent from my XT1585 using EO Forums mobile app

It was intermittent, but driven that way until it was continuous. Did the frame shop get her straight? Any lingering effects of the accident? Sent from my XT1585 using EO Forums mobile app

I'm glad you got it to work the way you liked. Remember that brake switch harness break you suffered? I finally had one come in doing the same thing. It took about two hours to find the break. Sent from my XT1585 using EO Forums mobile app

Occasionally the blower resistor also gets damaged, but generally speaking replacing the switch and repairing the harness and connector solves everything. Sent from my XT1585 using EO Forums mobile app

Hi Aaron, Yes, the blower motor always has power. It grounds through the blower motor switch. The switch and its connector get fried when old blower motors start consuming too much power. You have fixed the root cause, now pop out the switch and look at the connector. Replacement connector...

If you get good at Hino burners, you'll be very popular. The vehicle batteries or connections are bad. The dcu is seeing low voltage during cranking. It does not have an internal battery. I probably worded that wrong. Now, if possible I'd like you to put the soot at 2.3, set up those...

After you download the burner log, close the download screen. On the main screen there should be a print button, you can see a print preview. You can view it from there. At idle with the exhaust brake on, you should see approx 5-8 psi. If it's higher, unscrew the tiny braided hose and check...

The DCU is the Dosing Control Unit. It is located right above the DEF tank. It controls the DEF pump, which is right behind the DEF tank. The BCU is the burner control unit. If you were to remove the left front fender, you'd see it above the burner. The atomizer is a real joy to replace. It...

The DCU needs an update, and replace the batteries The latest DCU software is E0142. That code in the DCU suggests that your batteries are getting pretty crappy. Also I think that there's an ECU update due.

While you're at it, while in the BCU diagnostic menu, there is a tab you can select and it'll allow you to download the burner event log. when it's finished downloading, exit that page then hit print. It should print to pdf. See if there are lost flame events, or other events with flame temps...

If the DPR graph is between 3 and 9 bars, the DPR button will function. It will not do anything at 0-2 bars unless it was specifically configured to do so. P2436 is not good at all. This very often means the atomizer has an unfixable internal fault. P2030 means that the burner is not coming...

The first thing to do is to learn how to force a regen without using the DPR check function. If you force a regen through the engine ECU menu, you won't be able to watch the bcu. Leave the ecu diagnostic menu and enter the ecu customization menu. This differs depending on if you're using DX...

You have figured out how to connect to the ecu. How about the BCU? Are you using DX or dx2? Sent from my XT1585 using EO Forums mobile app

Also, P141F is a generic code sent from the burner control unit to the ECU, requesting the check engine light. The real codes are in the BCU, and I don't know of any software aside from Hino DX that will read them.

Hi Scott. This system is going to be very difficult to diagnose without Hino DX software. Think of this system like a big Reddy heater. There's an atomizer which mixes air and fuel, injecting it into the burner through the nozzle. There are two spark plugs. There's also a combustion air...

Radiator by greasytshirt posted Jun 29, 2017 at 2:07 AM This radiator looked clean around the edges. Removing the intercooler revealed how dirty it actually was.

Does the fan clutch come on? You'll hear it cycle on and off as you're driving. Does the coolant level stay put, or are you having to add coolant? The radiator fins can get clogged, and it won't be noticeable at all until you get some stuff out of the way. You can try removing the...
