    Hi there. I have a 3rd generation 2015 Honda Fit LX with CVT. I reversed polarity jumpstarting it and now some of the smart electrical things don’t work. Here are some of them:
    – Cruise Control state resets when I turn off the ignition. I usually leave it in Main On state (press the Main button on the steering wheel) at all times and just press Set when I actually need CC. Now I have to press the Main button every time before Set.
    – Headlight’s Auto mode doesn’t work (lights go dark).
    – Central locking system (the buttons on the drivers side door that lock/unlock all doors) doesn’t work unless the ignition is on.
    – Remote key doesn’t work (the small led is flashing when I press buttons on the keyfob but nothing happens, the car won’t lock/unlock)
    – Power Windows buttons don’t work unless the ignition is on.
    – The stereo didn’t work but I was able to fix that by replacing a blown fuse.

    Everything else seems fine, the car runs, turn signals/lights/stoplights work.

    I have a new battery now, checked all fuses (Box A under the hood, Boxes A and B under the dash on the driver’s side). Only one was blown (the car stereo).
    What else can I check to narrow down the problem?
    Can I fix this without special tools?

    Suggest you research if there are fusable links that may have been damaged.
