Doing my camber fix, the 12V was disconnected, safely. The trip meter values were retained. Bob Wilson
That is good. How about radio presets, did you have any set? With our 3rd gen: disconnect the 12 volt, trip meters gone.
Maybe this is not an issue with the Prime. It's a known issue in the 2012-2015 Plug-in Prius. Wouldn't one be able to connect a small battery or trickle charger to the front jump terminal in the engine compartment when doing a battery change to keep all settings? Standard safety precautions, of course, to prevent the positive connector from coming in contact with the ground (chassis).
Yes, I do that, when for example: swapping to a new battery. But sometimes you disconnect the battery and want it truly disconnected, to avoid (for example) an off-the-rotor brake caliper possibly squirting out it's piston. Seem like the Prime (and maybe all 4th gens?) have more extensive non-volatile memory.
