Thanks for asking your question. I will try and help you out.
You may want to check for fuses in the battery box. I have seen some KW and Peterbilts have a fuse there.
Please reply back if you need more help or have more questions. I am happy to assist.
I did check those and all seem to be good.
Thanks for the information.
Then I must suspect a broken wire on pin 70. If all the fuses and relays are good. A broken wire in the harness must be the issue.
Can you tell me where 70 goes when it leaves the ecm?
Sorry. I can not. I'm not sure where it goes. I would suspect straight to the fuse.
