Its a prius. take it in,
lost of things to go wrong with any hybrid, due to huge complexity.
if serious DIY, and feel compelled to get shocked on HV?
then read the FSM buy it ran read all the pages on 3000
and on how not to get shocked and killed. do so , dont guess
study the book.

or go there, first google hit for 3000, read this ?

http://priuschat.com/threads/code-p3000.49355/

could it not just be, that you didnt follow the battery swap instructions
in the FSM then trip these/
reset them and see if they come back.

P3004 - Power Cable Malfunction 130 HV Battery Malfunction. When HV battery voltage becomes lower than inverter voltage
131 Power Cable Malfunction. When main fuse is blown out, service plug is disconnected or limiter resistance is cut off
133 HV Battery Malfunction. When inverter voltage sensor is malfunctioning or limiter resistance value increases

Toyota prius code P0A41

If neither of those two things fixed it, it's probably the motor/generator itself having an intermittent open circuit in one of the windings. New motor (MG-1) time, I'm afraid.

Prius 2005 triangle indication

The Triangle indication:
Description: MASTER WARNING LIGHT.
The battery ECU has a self-diagnosis system. If the computer, High Voltage (HV) battery system or the components are not working properly, the ECU carries out a diagnosis to detect the malfunction, and illuminates the master warning light in the combination meter together with the HV system warning indicator on the multi information display.
NOTE:
The master warning light illuminates when the HV battery system fails and it blinks when in inspection mode.

It is your Hybrid Traction Battery. P3006 refers to a problem in cell number 6. It will need to be replaced or rebuilt. You can do it yourself with a replacement module from eBay. Watch some videos on youtube.

Finding bad cell in hv system. How do I remove the rear seat. After the service plug do you diconnect the cells from the busbsr and test them one at a time.

Hello. Welcome to FixYa.

I am a Toyota Service Manager, with all of the necessary Prius credentials..

I would seriously recommend that you do NOT fool with the HV battery, or anything inside the HV battery's protective case. Even with the service plug disconnected, you are dealing with potentially LETHAL voltages. 303 volts DC, to be exact. So, touching the wrong terminal at the wrong time could send those 303 volts across your heart, and that voltage is more than sufficient enough to stop your heart.

Plus, if you do find a bad cell, individual replacement cells are not available; you must obtain the entire HV battery.

In short, PLEASE stop what you are doing. You are taking a great risk.
If you do not have the in-depth knowledge with regard to proper handling of the HV battery, you are headed for a potential disaster.
