Toyota auris mk1 2011 p3004

Hello I’m having issues with my car.
So it started last week when i went off work and parked my car in the evening. Tried to start it it was no go ready blinks once. I can hear relays clicking once then ready comes off and I’m getting check hybrid system.

So far I replaced 12v battery. Checked fuses.

got my self obd reader and I’m getting this.

dr Prius shows voltages 15.70 to 15.78 after sitting for 7 days

 

The recall in question has been attended years ago. no outstaning.
Just ordered used inverter off ebay going to long shoot it.

 

Update
Cant find edit option on phone. Sooo in meanwhile waiting for the inverter. I disassembled the HV relay box. It looks pristine. Same thing to cables no corrosion whatsoever on high voltage battery side. Also tested relays and the white thing which I believe is some kind of resistor moulded in casing. Waiting for inverter then

 

Update for future reference.

Soooo i finally got hold on spare inverter cheap off ebay. Replaced it in like 1 hour without any mechanic experience. (got electrical backgound only) So after replacing the inverter car works without any codes. A presume other codes showed up either due inverter fail or just response to tweaking with fuses.

Did not had to clear any codes after inverter replacement.

So basically auris 2009-2012 is also affected by the same inverter issues as gen3.

And when i was playing with HV battery i found large amounts of moisture on the car frame the leak was in the boot from wiper fluid seal cleaned it and gave it good amout of clear seal just for good measure.
