    Hi folks, I saw a number of you post about the check engine light/system error that says Plug-in Charging Error, Power Limited (or something like that). Sounds like most of you had that problem while trying to charge (L2). We were driving and the error popped up close to home. There's still 39% (15 mi) supposedly remaining in battery power and we'd not been charging it. The OBD II reader reports fault code U0296 that brings up a generic error saying:
    type: Network - Network Communication - ISO/SAE Controlled
    description: Lost communication with AC to DC converter control module "A"
    Anyone have resolution to this problem? We've turned the car off and on and few times and error persists. I hesitate to clear the fault code. Is this really something Honda will have to repair or does disconnecting negative battery terminal work to reboot and resolve the error?

    I suggest taking it to the dealer. Even if you could clear the fault, the only way Honda learns about these issues is through owners taking their cars to service departments. You also want to have the issue on record in case it happens again out of warranty. I hope all is well and it was just a signal or sensor or software hiccup.

    Has anyone had the issue and the dealer actually fixed it?

    Yes, you are lucky that the fault seems to be persistent. The dealer will often dismiss problems which aren't there when you arrive.

    CORRECTION: the error says "Plug-in Power System Problem. Range Limited." OBDII: U0296 (can't change the thread title)
