Thank you for that

does it crank over and start ??

Customer: replied 3 months ago.
Ir cranks it starts it runs fine thereis no engine problems just dash gauges a/c and radio. The gauges work and then it goes out on a blick then comes back up. A/C dont work.
Expert:  Wayne replied 3 months ago.

Thank you for that

that code this is what the book says

Connector #4007 Pin #E Electric horn under current
The Current from this output is below 0.5 A
Open circuit

For your AC check for a complete system charge to be sure the pressure switches are getting enough pressure to allow the compressor to cut in. If so check for a faulty switch and harness. Other potential causes are fuses and relays, Faulty harness or pressure switch. Check the harness and pressure switches

Customer: replied 3 months ago.
I been through the whole harness and checked all fuses all relays all modules and all connectors. I checked all pressure switches and wire to and from switches any thing else you got?
Customer: replied 3 months ago.
I also have the book i know what the code means but is there something else that I am missing. How can the a/c the radio and the dash gauges work sometimes and don't work other times.

hi im alex, have you had this hooked up to DLB navistar software?

Customer: replied 3 months ago.
Nope i dont have it hooked up yet but maybe i could
Expert:  Alex Olsen replied 3 months ago.

yea the a/c is controlled by the body controller, if there is no power with the a/c on then body controller is shutting down ac system , this is a first gen body controller a simple softwear update could fix all these problems have seen it tons of times

Expert:  Alex Olsen replied 3 months ago.

do you need any help on this?

Customer: replied 3 months ago.
Do you have any idea why the dash gauges go out on a blink and come back up in a few seconds? I hooked up DLB no comm for any module but the truck runs just fine.
Expert:  Alex Olsen replied 3 months ago.

and no other warning lights on? i would check data link at the diagnostic connector

Customer: replied 3 months ago.
I have checked DLC wires all hooked up and got powers and grounds but no comm. Something is shorting the comm out.
Expert:  Alex Olsen replied 3 months ago.

you have 60ohms at the connector?

Customer: replied 3 months ago.
sir
Expert:  Alex Olsen replied 3 months ago.

do you have engine software? can you connect to engine?

Customer: replied 3 months ago.
Can't connect to engine I was looking for the software version on the body controller but still no comm probably take computer out and take to dealer but you think I am still missing something?
Expert:  Alex Olsen replied 3 months ago.

yes this dosent seem right, the engine is on the 1708 data link should beable to communicate with it, you can hook to another truck with comm adapter you are using?

Customer: replied 3 months ago.
my computer hooks up fine to another truck I tried 1708 and the 1939 comms and still got nothing no abs, engine module, or trans module comm.
Expert:  Alex Olsen replied 3 months ago.

ok i would unplug all but one module see if you can connect to just one, if you can plug in another
