Hello everyone, I have a 2014 RAM 2500 with just 200k miles.
Around 140k, I changed the injectors, trans, and turbo actuator.
I replaced it with the City Diesel billet actuator.
It was working perfectly until the other day.
I leave my exhaust brake on auto, so it gets used every time I drive it.
I got the U code that says communication loss with turbo actuator.
I checked the plug, and I had 12v on the correct pin.
I'm wondering if anyone else has had this issue. Everything I have found related to my problem is with failed stock actuators, and the solution is to upgrade to the one I have.
I got the DDP turbo actuator code guide, and it says to check the can pins for 115-125 ohms on the actuator side and truck side of the harness.
I need to recheck that. When I checked it the other day, the actuator had 120 at first but didn't when I checked it again.
I can't find any example of a City Diesel actuator failing.
So now I'm trying to determine whether the truck wiring going to the actuator is damaged or if the actuator itself failed.
If the turbo goes bad where the vanes wouldn't move, I should be getting different codes, so I don't think that is the issue.
Has anyone ever had a similar issue?
Thanks!
