LMTV M1078 All five lights on CTIS solid not flashing.

[JRKJeeper]

I looked all over the forum and only see posts about the lights flashing. On a recently purchase LMTV my lights all just stay on red. No sounds nothing. I looked in the troubleshooting but it stops at 4 lights lit up.

5 solids is an unrecoverable internal fault. You can try hitting it with a hammer, but beyond that it is now a paperweight.

Mine was the same, I used 3 switches, a relay and a pressure gauge and control it manually. Search electric over pneumatic manual ctis, also have videos on utube under username rronmar($30-50 to build yourself?)

You can get another controller, or an acrduino based alternative developed by a user here, $350-???...

Thank you! You are a gentleman and a scholar. I’ll look for your videos and see if I can find the user who developed one.

My issue now is I’m to new to message him. So I can’t get there attention to say I want one.

Read through my recent thread first. You can find the Dana controllers pretty cheap on ebay, etc and they are pretty decent actually. More rugged and environment proof for sure and with the diagnostic software and their ability to output fault codes, etc I find they work well.

CTIS pressure settings increase - no programming, transducer, or module required.

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...

I looked through your thread and im interested. What do I need to buy with the dana unit to make it work on the m1078A1?

Not sure I understand the question - the Dana/Spicer/Eaton CTIS controller is stock for our trucks.

sorry for my not knowing. So I can remove the dead green unit I have and just plug the black dana one in and ill be back working again? I know that depends on the rest of the systems condition.

Yes…

The A1 and later trucks all use the same controller since they all use ECM controlled engines. The early one's were green and the later ones or replacement units are black.

I thought there were 2 types of black controller, one that could be accessed with the diagnostic port and one that couldn't?

Both of the black controllers and even the green controller will talk to the diagnostic software with J1708. It's only the later black controllers that will speak the faster J1939 protocol. They all interface with the software - as far as I know even the A0 one's do if you acquire or build the breakout cable.

 

[Ronmar]

yep, pretty sure you can talk to all of them with the correct interface…

Good deal, just found one of these I'll be playing around with shortly.

You may or may not be wired over to the CTIS from the diagnostic port. I'm not familiar with LMTV trucks I just know my M936A2 wasn't wired for it. So I made an adapter/breakout cable I plug between the CTIS controller and the harness. I then use the dearborn adapter and plug adapter from the kit pictured (STE/ICE) to plug in to a laptop with the Dana software. It works very well. The older boxes I can't talk to but the newer (black) boxes with the J1939 protocol work great. The pinouts and software are available online as well as the CTIS controllers that have which protocols.
