bubbamobilin Posted November 29, 2020 Share Posted November 29, 2020 Just got finished serving my 2016 MP8 505. Go to crank it and the shut down light and electronic malfunction light are on. My scan tool shows code U010C which is lost communication with the turbo. What caused this? Where should I start looking. All the wires and harnesses look intact around the turbo.

fjh Posted November 29, 2020 Share Posted November 29, 2020 Check the plug below the turbo! Quote Link to comment https://www.bigmacktrucks.com/topic/65089-mp8-lost-communication-with-turbo/#findComment-464563 Share on other sites More sharing options...
bubbamobilin Posted November 29, 2020 Author Share Posted November 29, 2020 I appreciate it. There are 2 harnesses that go to the turbo. I unplugged both and blew them out with air but no success.

Mackpro Posted November 30, 2020 Share Posted November 30, 2020 There is a fuse for the turbo , I can’t remember which fuse box it’s in though. Also, other sensors on the same 1939 data that the turbo is on could be shorting out causing the issue. On some year models the DEF level sensor is on the same data link as the turbo. Make sure your DEF level guage is working Quote Link to comment https://www.bigmacktrucks.com/topic/65089-mp8-lost-communication-with-turbo/#findComment-464611 Share on other sites More sharing options...
steeler Posted November 30, 2020 Share Posted November 30, 2020 The fuse for the turbo is in the panel by your left foot.I can't remember which one (p13 maybe).

bubbamobilin Posted November 30, 2020 Author Share Posted November 30, 2020 Thanks for the info. The turbo fuse is p16 but that's not the problem. Dropped it off at the Mack dealer. I'll give an update when they find the problem.
