It would help if you pulled the codes and posted them. Your best shot is to get a mini vci cable & Techstream software--it's the pirated version of the Toyota software and will show the codes, HV battery condition, etc. Cheap on Amazon & Ebay. Also if you're needing jumps on the little battery in back, you probably have a bad battery or a parasitic drain. When you reset, you also reset the readiness monitors. When those turn back on, your codes are detected & set. Really no good alternative to getting the problems fixed.
You should get a set of service manuals. You can find them on Ebay, any set for 01 to 03 will do. Rockauto carries BISHKO 10503 BOUND for $100 both of the major manuals, they are factory reprints. If you get stuck, the bay area is a great place for indy Prius garages--look up Luscious Garage. Probably spendy, but they sure do know their stuff.
