    I have a 2009 Prius with 147k miles. It keeps blowing the AM2 fuse. I already did the Inverter pump disconnect test and still blows the fuse. I also hooked up two other inverter pumps and still blows the fuse. I put a 30 amp fuse in there and I get dash lights but no engine start and I get ready mode for maybe a half of a second then back off it goes.. I plan on changing the inverter next to see if that's what the problem is. with 30 amp fuse in and dash lights on I get codes U0100 P3000 C1310 C 1259. Anyone else ever deal with this problem?

    I am very familiar with the Prius. I have the Hybrid orange plug seated correctly. Ive checked all other fuses they are fine. The 12volt battery is new and charged, I also keep a jump pack on when attempting to power it on. If I have a 15 amp fuse in the AM2 slot, the fuse instantly blows right when the power button is pressed.

    I am very familiar with the Prius.

    Have you reviewed the wiring diagram to determine all the loads supplied by the AM2 fuse? It supplies quite a bit more than just the ICWS. I think there may even be an old post here somewhere for that. hmm..that thread may have been for the DOME fuse. regardless, a wiring diagram needs to be in your future or you're probably going to spend a lot of time chasing your tail.

    Hello Saviorcrash, I am having similar symptoms after I assumed the inverter pump burnt up due to heavy mountain driving. I replaced the pump, and the AM2 fuse continues to blow, even with the pump unplugged... What did you ultimately find as a solution? I am starting to think it is possible that some of the wires somewhere else on the AM2 circuit are shorting or perhaps the Integration Relay C (82641-47020) that the AM2 fuse is located on is failing somehow.

    Any info you can provide would be greatly appreciated in helping me find a fix!
