Diagnosis Based on Diagnostic Trouble Code (DTC) DTC 19 ABS Operation Signal (Wire Breaking/Short Circuit) Explanation of Circuit: When the signal from Electronic Brake Control Module (EBCM) is supplied to the Transmission Control Module (TCM) the TCM judges the operating condition of the...

Roger you forgot to mention what year your W4 was. I attached the troubleshooting guide for a FC 19 from 1999-2004 take a look and see if it looks applicable to your unit. I have seen issues with the exhaust brake relay in the dash. I would perform your voltage and ground measurements from there...

That's plausible for sure, I've seen it happen. PM me your vin and let me check your warranty history. If it did fail, something made it fail such as overfueling injectors, a mis adjusted exhaust brake or an issue with the Atomization module overfueling. Without fixing the root cause your going...

If you pm me your vin I can check warranty coverages and see if you have any outstanding recalls.

My advise is if it is under warranty take it to the dealer. Your going to be hard pressesd to have someone diagnose a vibration issue without having hands and eyes on it. IMHO they all have some vibration at 1000 rpm.

If you brought the truck to my dealership yes that is how I would install them. Like I said most batt shops may be able to do it cheaper but when It comes to batteries id go for quality. I attached the PDF here and pm messaged it to you also. Let u know how it works out.

Tony found his air tank pressure switch was faulty (shorted) and causing his Meter black out FYI.

Like Treadmill said yes you can. I would recommend it. Hino has a Tech tip on switching over from group 27's to group 31 type batteries. I have attached most of the info and part numbers. Any battery shop should be able to help you out, or you can go to the dealer and ask them for the parts or...

If its not visibly leaking fuel I would assume its not leaking fuel. If it was leaking there would be a wet spot somewhere. Its very common for the exhaust manifold studs to brake on the 4 cylinder engines. There usually they break in the the #1 or #4 cylinders. If you can peek in and look to...

No problem. Glad you reported back with your findings.

Its just for setting the proper electrode gap between the two igniters. Good question.

That's a very common issue. There is a proper fix that involves just replacing the brake pedal spring. This will cure your issue permanently or you can just adjust the switch every 6 months or so. To adjust the switch, turn it left, then push it down so it makes good contact then turn it right...

I see now it says you have pressure in your wet tank. I would drain it, replace the cartridge. Then see what happens. If your in a cold climate the cartridge could be frozen not enough details to figure that out. Filters are cheap and it could probably use one anyways. I usually recommend...

I would remove the discharge line from the inlet of the Air drier assembly.This would be the large line coming in. I would then run the truck and inspect the line for signs oil heavy oil and be sure the air compressor is capable of compressing air. That will split the system in half. If it...

Im dying to know. I wonder if he just ran out of Ether:boom:

I did nothing and it just started working again on my end. Must have been a glitch form updating the site. Were good to go now.

Well now I know that it has actual issues thats a different story. I have on the rare occasion seen the air pressure sensors for the air tanks short and black out the meter. I had a newer rollback truck and the Meter went blank except for a few indicators. If you removed the meter and plugged it...

I’m still unable to get messages. Says I have 11 now. If anyone had the same issue and can now obtain messages I’m all ears.

When I first started working on Hinos I would get this code all the time. I never found anything of note. It sets when you connect a devise to the data link on some units. When you plug into the DLC it causes a can block initially and sets the code. I don’t even notice it anymore. If it’s...

I cant find where my messages have gone. It shows that I have 8 messages in the status bar, but I can not find the link to open them. Anyone else having this issue?
