    I have a rattle in the dash so I went digging for it. Removed the instrument panel to address the issue. Plugged it back in and now the readout for the hybrid battery isn’t reading correctly. Instead it reads nothing but when I accelerate it goes up and then down. Now I don’t know how much the hybrid battery is charged. How do I reset that so it reads correctly?

    make sure you didn't damage the pins, it is locked tightly, and there is no wiring damage.
    then disconnect the 12v negative for a minute

    I will try that. Didn’t have any issues plugging it back in but the idea makes sense.

    Btw, I never found the rattle but I know it’s in the top cover of the dash. Possibly something fell into the front windshield defrost vent? Do you have any info how to remove the top cover?

    Well, no damaged pins or wires. Connectors snug. Disconnected negative terminal for about 30 minutes.Combo meter still blank accept when accelerating or decelerating.

    Dufas says there are three different settings for the combo meter. YouTube it.

    My 2017 PP has rattle sounds coming from the dash as well. Too lazy to disassemble to figure it out and Ive been living with that for past 7 years. I cannot live with clicking, ticking sounds coming from the driver side front wheel or axle.
