Anyone passing through VA, 95 corridor? We are slower than hell, in and out no problem.

It's either a P204F or P207F. In any case, what you are seeing is a generic "something is wrong with the scr system" code being sent from the DCU to the ECU. The DCU is telling to ECU to turn on the check engine light. To find the ACTUAL codes, you'd need to be able to talk to the module...

Look at the rear of the exhaust. There's a thing with three pipes going to it, and an electrical connector. Tell me some backstory. Any warning lights? If you've got dealer software that's good. If not, you're in trouble.

I never would have though of that unless I was right there! Glad you've gotten it sorted out.

Be aware that there are two fuse boxes. The primary box, which is outside near the battery box, usually has a few inside that blow. Tools are needed to replace the large fusible links. If the ABS light thing is new, it just so happens that the TCM and ABS ECU are on the 1708 CAN. In other...

This is a problem. You're describing a case where the tcm does not have power. It's either a fuse you've yet to discover, the ground wire for the tcm is bad/fried, the tcm has fried, or there's some other fault that is causing the tcm to not communicate with the rest of the truck. It's not...

Is there a small spin on filter on the front left of the transmission?

Allison 3000RDS?

Did you accidently have the jumper cables reversed? It's a common mistake, the positive posts are toward the inside, and there's a red stripe on the negative battery cables. Since it worked correctly before jump starting (I assume), I'm pretty sure you blew a fuse. Check EVERY SINGLE FUSE...

Just eyeballing it, if the box was lowered to be even with the bottom of the sleeper (4-5 in, maybe), it looks like the clearance between the tires and bottom of box will be...minimal. Would to help to see it in person, though.

Sounds like they shoved a 6x6 in there. That's ridiculous. If you drop it to an inch, will the tires hit body crossmembers, especially under load?

You had mentioned tire sizes in a different thread. Do you move to a larger diameter?

Id take it to an Allison shop simply because they have the software.

Pretty sure that's still under warranty.

Where are you located? It may or may not have a def quality sensor in the tank, depends on VIN. If yes, dealer software needed to turn off light. If no, check both nox sensors. The newest ones end with E0451. You will need to replace both if the p/n ends with E0450 or 0020. If those are...

The 2007 did not come with an exhaust brake, but it could be ordered with one, or a Pacbrake could be added. The factory brake functions when certain conditions are met. The accelerator position needs to be at zero, the idle validation switch needs to be on, and there can't be any active abs...

The 9-speed was an uncommon option here, and I've never had to deal with one. All of the manual transmission Hinos I've seen have a simple hydraulic clutch with a master and slave cylinder with no clutch booster. So I can't offer specifics. All I can tell you is to adjust the clutch until you...

Yep. I need more info on this thing.

Im not familiar with that model. Did you mean an SG? What is your location?

Replacing kingpins in my driveway.
