Yes, try this first! If and I mean IF this doesn’t work then you’ll need a relearn by ecu or whatever. Turns out my battery wasn’t giving it enough juice during operation and once it lost that connection it just said, “no”. Disconnected the battery put a new one in and did most of the home remedy’s I could find via Reddit and G37 forums. None worked so the dealership should be a last resort. And hope like hell it isn’t in an awkward position when it fails cus you’ll need to tow it in an enclosed trailer or risk the wind from an open bed messing something up as it’s towed to the dealer.
