All, Got "Check Hybrid System" and no start when I tried to start the car on Sunday. Started with the 12v battery, as it was 8.5 years old. After replacing with a new battery, same code. Hooked up a basic obd2 scanner/Dr. Prius android app, and it throws code P3004. Unfortunately, it can't read the detail code. It does seem to show that all the battery cells look strong. Any ideas before I have this thing towed to the dealership? Thanks!
practically the whole of the high voltage harness. problem can be at any point, battery, a/c compressor, tranny, or anywhere in between. you're right about tech stream. but if you're going to diy, a lot of work is involved all around. the work has to be worth more than paying someone, or else it isn't worth the trouble.
