2001 battery/computer problem with error codes

Hey guys,

My 2001 Prius acts like I have some bad NIMH modules.

Keeps giving me code P3006 for high differential and P30011 and P3015 on my SGII.

Battery level on MFD varies easily from 25% to 100%

Car goes into high rev mode with battery fans on until I pull over and restart the car. What happens when I get this condition.

Way I see it, modules 1 and 5 need replaced, and I'm in the process of trying to get the HV battery apart right now. But the cold weather here in PA makes it slow going for now. Any hints?

I've hjust started to remove some brackets on the case that attaches the battery to the car. Mostly seems like I just have to plug away and figure it out as I go.

Also, just see 1 vendor on ebay right now for gen 1 battery. Any recommendations on where to get some modules?

Thanks for any input...
