grandson jumped 05 prius, no start, main fuse blown

yea, tried that last time just melted it more than what it was.




Merged.

I will look it up , I just bought inverter & fuse box ( the hole thing) dropped right off @ my door step all for a $110.00 dollars not a bad price in my book.

 

It took some searching on car-part.com there are a lot of them out there I got lucky this guy just wanted to get this out of his inventory ( smart guy!) but alot of these guys think they have the last one around & think they can get it, a lot of the local yards around me thought that too. I called lkq a national salvage parts co. & they just got one locally & would not hook me up with the local yards here ( there call center was in Texas) she told me that I had to drive 30 miles to there place to get the price! I told her that is one of the stupidest things said! she really didn't care & hung up. I will teach my son inlaw today how to swap this out. I still got the old one from last time. I did take the bottom plate off of the bottom & found the burnt components they look like mico circuts not going to attempt to fix not that good @ electronics repair.

 

Ok , just got done replaced Inverter, main fuse & found another fuse I think it was etc fuse which was blown & cleared codes got another code now it is P0AEE, & got red trinangle still no start never had that code before so this is new to me the start button will not go green or the ready lite on dash either, I tried to clear code it is a hard code & come back right away, kinda stuck now going to do some more reading I guess.

 

yea we got that to go away but other codes, got these & triangle to disappear aft resetting codes a couple of times, swaped out inverter before this BUT getting check engine lite on , brake lite on , abs on & no ready lite & key botton just amber no green the only thing that keeps coming up is code B2799 which is the emoblizer for the key tried both keys no luck. can't run car for a long time don't want to kill hybrid battery so do a couple of differnt things & than let it rest. we had a spare hv ecu & tried that no luck either.

 

just read your thread on the hv ecu replacement! boy am I glad I didn't try to start car 20 or more times! how do I register ID number for icu? I got a mini vci on my lap top but have not used it yet. I bought it to use on my 2001 Prius will it work on this car?

 

well just went over there & jumperd obd 2 plug for 32 mins, got code to clear pulled 12v neg off for a couple of mins & hooked back up that cleared red triangle &imobilizer code still can't get car to go into the ready mode but the battery ( hybird) is about down to 1 bar now was going to put on grid charger before trying again, 12 v is new with battery charger on it ( 13.8 v) going to check the brake switch too. what do you think?

 

yes I bought a grid charger for my 2001 prius person I bought it from said I cad use it on gen 2 prius only thing was his directions for hook up on gen 2 are vague, I watched video on system & neg. side of battery ( hybird) is the one with 2 relays don't go by color of wires, ( my 2001 is color coded ) I will check voltage again battery seems to recover a little bit aft sitting, ( yes I do have rubber electricians gloves that I always use) the thing I can't figure out is why the drain on hybird battery goes on when it is not even coming on? ( when were not in the ready mode) I can hear the pump running for the inverter cooling I thought that runs off of the 12v system am I wrong on that?

 

no codes! aft I cleared all, no codes, will not go into ready mode. ( codes where due to previous issues)

 

a scanner I bought at sears, I have a mini vci it is a p.o.s. everytime I try to use it it is looking for password & a bunch of other info to work! I bought it off of e-bay had to get computer geek to install, doesn't work!

 

well, I did some more reading in the service manual & did a sequence of operation, I think what I will do is swap out the power source ecu that is under the dash on the drivers side up behind the steering wheel everything goes through there before it sends signal to hv ecu to start system, I did test on brake switch that test out ok, so I can get the part cheap off of e-bay. I called toyota first to give them my vin to make sure the part would fit he informed me that we had to go off of the production date & year & found that the power souce ecu for the 2005 was only used for a short time sept 04 thru nov o5 and that will only work with that part number for that production dates only! he told me that toyota can not even get that part any more ( 89618-47011) that it was discontinued, so that makes me wonder if they had issues with these early ones that they changed to something else.( different part no. ) the biggest problem now is how to get the dash taken apart to put this part in.
