U010C Loss comminication with Turbo

[BuellBlackbelt]

So my next saga, I have the code U010C - loss communication with Turbo code pop up... found that my 12v feed wire is not getting 12V.

Is there a fuse that could be blown?

I just had the PCM switched out due to the Alternator situation in the past.

Any help would be GREATLY appreciated.

U010C is an actuator failure. (Seems to be a massive number of these failing lately..thats concerning).

Prepare your bhole & wallet.

i have read these and yes i am hoping that is not it.. however the issue is the 12 volt source wire on the 4 port connection is not getting power from the PCM

I'm pretty certain that the actuator is not a 12v item, it's a 5v.

Are you getting 0v on the port?

I had a similar issue on my 2011, fuse M21 was blown, repaired a bare wire, replace the fuse, good to go.

I had the same code pop up last week. Happened early morning while cold, just hit the cold season in Cali (low 50s lmao) I would get boost back after a couple hundred feet. Code went away for a few days then came back early morning. It’s been off for about a week now. Hoping it’s just a fuse or wire thing.

Where is the M21 fuse.. I have read this and i can't find the dang thing. i am thinking the wire is also bad on my truck. Long story short my idle pulley bearings went out a few weeks back and when the belt came off it bumped the wire harness and two wires going to my Alternator were damaged... think the Turbo wires were as well. cause the code came up the exact time the belt came off..

You sure it's M21? This is from a '17. There is K & F but no M.

On my 2011, it was M21, 20amp fuse labeled ASD #3.
The middle wire for my MAF sensor chaffed and the bare wire shorted out blowing that fuse and throwing U010C for the turbo and P0102 for the MAF sensor. Repaired the wire, replaced the fuse and all was good again.
