Agree. Wouldn't delete them. We have a good community/network of FMTV and other military vehicles throughout the country on this forum and the facebook groups, etc and some of us have tow bars, air hoses, and interconnect cables that can allow us to rescue or be rescued. Not having the front...

These are all good too. Down to semantics but I would call these preventative maintenance. Fixing to me addresses something that is broken or missing. Fine lines between preventative maintenance, fixes, upgrades, and modifications. They all land on a spectrum somewhere for sure but fuel hoses...

Doubt that would work without a LOT of effort. A lot of this software is cracked and relies on direct hardware access and has problems working even under actual windows machines. It's flaky and difficult to get to work under the best conditions. It you have all the time in the world to devote...

As a software engineer in a former career path I understand the sentiment and for me the disembodied hand of Steve Jobs ghost can keep his bony fingers the hell out of my wallet..... but all that aside - the military standardized on Windows so if you want to have any meaningful coms with the...

ECO hubs (#1 with a bullet) Cruise Control Factory style A1P2 air conditioning 370 HP ECM flash Gen 1 HIMARS turret hatch.

The one I linked to is the NSN/part number called out by the A1R/A1P2 parts manual as fitting trucks with serial numbers above 100,623 The older valve is part number QS5-5CTP or NSN 4810-01-442-8695 The older trucks used two intake "atomizers" while the C7 trucks use one. They are not the same...

This is the US Army - not NASA. That's a sealed unit and has no maintenance. Operator PMCS: Monthly 0.1 Ether Starting Aid 1. Check ether cylinder (Figure 3, Item 1) for loose or damaged mounts and hardware. Check ether cylinder and injection valve (Figure 3, Item 2) for damage. So...

It depends on which controller you have, and the power/ground/open state of pins M and Z. And as Ronmar pointed out you could have a skewed pressure transducer signal, or someone changed the programing with the diagnostic software. Best way to know for sure is to hookup the diagnostic software...

The listing says MRAP, M939, FMTV, LMTV. Guessing it would fit an M35A3 also.... probably other stuff as well. There are no stock programs I'm aware of that run 65 to 70 psi in HWY. You will have to program it. Also what you "guess" and what a tire chalk says and what the truck decides it's...

Not really, no. You can find the Dana controllers brand new for like $600 to $700. And used one's are $100 to $200 and will continue to land on the surplus market for decades in both new and used form. With the free software, an RP1210 adapter that you should probably have anyway if you have an...

I've had one of the 5 light failures also. But the one and only Arduino I've touched was also bricked. So there's that. They have continued to make improvements in the controllers - the one I'm currently using is a 2012 black case unit that can coms with J1939. @Lostchain has a 2016 unit that's...

The Dana controllers are pretty good actually. Especially the later black unit that speaks J1939. That's the only one to get IMO. The Arduino option(s?) are interesting but the truck I'm troubleshooting at the moment seems to have bricked one of those (lights up and then the display just fades...

My point is you can get the exact same effect with a SPST switch and a few inches of wire. No transducer, no plumbing, no 12 feet of wire, and it doesn't throw off the controllers atmospheric pressure reading. And with a SPDT switch, and a few more inches of wire to a ground you can have 12...

Well this is going to make a few people (including myself) feel really silly...... I've been getting pretty deep into a CTIS diag on a friends truck and had the occasion to swap modules between my truck and his, and vice-versa. And I've been going over documentation and troubleshooting info and...

Have you looked at the spring steel inside the track? It doesn't fall out and isn't always apparent that it's broken till you remove it from the door.

I don't think you understand. Outside of a brand new truck or a brand new door for a truck - I would wager no one here has ever seen one that isn't broken. Buying a used one is a waste of money because buying a new one is likely a waste of money. They sucked and never got redesigned - the...

Those are essentially always broken in that exact way on every truck and if you buy a used one that isn't broken it will be shortly. Use that information however you like.

Yes - possible ground is another good call - check the one that's on the same part of the harness as the washer fluid pump. That one is involved in the headlight circuit. It's inside the driver's step on the older trucks - not entirely positive where it's at on the A1P2 without looking at one...

You can sort-of disassemble the end of the turn signal stalk - where the washer function sleeve is. Pull that off and inspect the contacts...... you probably need to replace it. Does the horn and washer function work? Welcome to German plastic truck controls..... 🙄

Disconnect the turn signal switch and see if it stops?
