So just inspected my ground wires. The 12V to chassis is fine - looks practically new. HOWEVER, the one that goes from the chassis to transmission looks completely corroded, and the one that goes from the chassis to intake or IMA motor (whatever that black box is, I haven't opened it yet to find out) is corroded AND CUT. Literally cut in half and not connected at all.

The mechanic that did my valve adjustment graciously hooked up his diagnostic computer to the Insight for me to use to diagnose the problem.

(Shoutout to Chris from Crown Motors in Holland, MI! Amazing guy with years of expertise in all things Honda!)

There is one persistent code that pops up, but it isn't throwing a CEL. That code is P0AA6, which is "High Voltage Short Circuit", and is the same code that popped up yesterday. Research seems to indicate a ground strap issue, which I know I have after inspecting. Will be replacing the ground straps ASAP as well as ordering a new 12V battery. I probably won't get sub-zero temperatures here, but I can't guarantee it, so I'll stick with the typical lead acid since the hybrid battery works fine. There are no codes whatsoever for hybrid battery deterioration.

Hopefully this helps fix all the issues!

(smacks myself for being so ready to throw out the IMA)

EDIT: $90 later and I just finished installing the new 12V battery. 500 cold cranking amps; I think the old one was only 400 or 450. Ground straps will arrive Tuesday. Cost $14.60, original Honda parts.
Is it okay to keep driving the Insight until then, or should I park it until I install the new ground straps? Or should I bypass the IMA until then?
