2011 International Prostar many odd electrical issues

I have a customer with the exact same issue as well any resolution.
He's already lost his job with his carrier.
I would like to help if possible.

 

Did you already follow steps in previous posts?

 

I have a 2011 prostar I changed ac compressor , pressure switch, and both sensors but avec still not working. Anybody can help me at this time

 

AC is computer controlled on those. Unless you get someone to connect to it with Diamond logic software, you'll just be guessing.

 

Hello,
I'm having this same exact issue going on with my 2010 international. Question, has anyone answered it and finding out the answer to it?

 

i got 2010 international , the jake switch don't work, neither does regen, and other switches in this strip. fuses are good, i swapped the switch pack with another truck just like it same-same and it doesn't work ? both switch packs are good because the good truck worked with switch pack i assumed is bad. i got a bootleg version of diamond builder where would i go to reset module or where is module for these switches. i been looking at several threads and you seem to be the most knowledgeable with these internationals. thanks i hope to here soon

 

was wondering if you can help me out , 2010 international dash switch pack not working (jakes, regen, slide 5th wheel ) you get it. fuses are good. I swapped out switch pack from other truck that is working..switch pack is good cause it worked on good truck. i have a ghetto bootleg version of diamond builder and its kind of confusing with all those symbols and #### must be masons anyways. where can i start to reset module or where is module for these switches i can probably swap them out faster than playing ohm meter boy. i could use your help you seem like you know these trucks ....btw you part of the A TEAM....

 

Are you sure the terminals are good at the fuse? They like to spread apart.

 

At the wiring connector for the switch pack, with key on, you should have 12 volts at the light blue wire. The white wire is ground. The dark blue is powered when the lights are on. The twisted pair is the datalink wiring. The switch packs are wired in a series chain if you have more than one. So make sure they are plugged in so that they form a chain with one plugged into the main harness. It is possible to plug them in to form a loop so that they are only plugged into themselves and not actually into the truck harness and that might be why it isn't working.
