Sorry for the gap between replies i checked those pins continuity is 0 ohms. I pulled the connector didnt see any spread pins or anything wires all seem connected good into the plastic. Im not sure what else i can do. This summer ill be pulling the dash and motor to put in a 24v and all wiring modules etc. is there a way i can run cruise control and ac without the PCM until then or no?

Will do i should be home for a but after today its outage season so work is pretty strong atm. Ill pull that plug and see whats what and check my continuity

I dont see any issues with the plugs on the female ends

Ill look at the plugs and see the pins looked ok when i cleaned the harness but ill look more thoroughly at it again

So i unplugged and plugged the pcm C3 in a couple times and OD light came back on im wondering if maybe the pcm isnt getting good connection should i use and grease or anything

I put the pcm back in this morning i have it just sitting with on screw holding it loosely for now i turned the key and the OD light isnt on anymore i have the ESS un plugged im gonna purchase a new one and gap it when i get a chance but the WTS still is staying on very curious

I had it all unwrapped and i cleaned all wiring and inspected it all ill have to look at it

Infinite continuity between PCM and ABS Pin 29/30 on C3 PCM and Pin 3/7 on ABS and i checked pin 29 to 3/7 and 30 to pin 3/7 just to be safe and nothing

Yup still not working i will check tonight

PCM came in today so fingers crossed although im not getting my hopes up No change so i think i should give up

I have an in cab meter thats in my switch panel for lights its at like 14.7v when running without lights but im going yo disconnect it when i put the pcm in and see if it gives me any response before hooking everything back up. When everything was working it was at 14.5 i think

Update on my PCM, got a text just now PCM was DOA according to builder. He told me to recheck all grounds and harness since he doesnt have another core if something fries this one. But he verified the replacement is working and communicating. So what should i triple check before installing PCM to make sure its not a installation error

Pcm is in the mail, noticed my aftermarket fuel level guage isnt reading anymore im guessing it has to do with the connection saying sensor return? Would that be a ground or 12v supply?

That is my thought but it is not giving me bias for the bus

.5/.6 v in pin 9 and 10 of C1 with PCM connected No bias at ABS module either Im gonna send the pcm to the builder tomorrow hes going to test it for me for communication and put it in a test truck What else should i check this is definitely a good indicator
