2014 Mack GU713 MP7...

2014 Mack GU713 MP7 code U010C FMI00 no comminication with turbocharger module.

Mechanic's Assistant: What's the make/model/year of your truck? Engine type?

Mack GU713 2014 MP7

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

Yes, i pulled up a wiring diagram and checked resistance between pin 36 on ecm to pin 5 on turbo module and got .02 ohms same with pin 35 on ecm and pin 6 on turbo module

Mechanic's Assistant: Anything else you want the Truck Mechanic to know before I connect you?

I try to actuate exhaust gas pressure regulator and it doesnt do anything. if that helps with diagnosing anything.
