Thread: U010C Trouble Code

    U010C Trouble Code

    Hi All-

    I keep getting a u010c trouble code saying "I've lost communication w/ the turbo/super charger control module.

    I had this pop up right after i done my last oil change about 2 months ago; been clearing the DTC out w/ my Ultra, but it comes back on in a few days or so.

    Most of the research I’ve done online is telling me I have a problem w/ the Turbo Actuator.

    Any suggestions or previous experience on what else might be causing the problem other than the actuator would be greatly appreciated before I consider dropping the money on a 2nd Gen Swap

    Looks like its the actuator.

    But the 2nd link offers a way to test and verify.

    Had that code pop for me on a trip a few weeks ago, turned out to be a blown fuse. Think it was M21 in my 2011. Worth a shot.
