    Car was driving fine until I went through some slightly flooded streets, when it was time to park I had the “transmission p lock mechanism is abnormal” message so I put my parking brake on. Came back out 2 hours later and car wouldn’t ready up with red triangle of death on dash. Thought it was from my old 12v so I got that changed but still no ready up. FIXD scanner is showing P0A40 and P0A41. Also some side info my splash guard is gone I literally just lost it a few weeks ago and didn’t get around to changing it.

    The water caused a short in the resolver system.
    Unfortunately, the only solution is close inspection of all the wiring, plugs and ecu.
    Try drying everything out thoroughly
