inverter replacement problem

You must be able to pull all the codes the car is throwing yourself. If not you will always be at the dealers mercy. Thats not necessary as you have DIY skills since you replaced the Inverter yourself. There are a few OBD Hybrid Capable Code readers out there pretty cheap.

Whatever code reader you get it must have Toyota Techstream software on board or it may not harvest all hybrid codes.

An android app for an android phone called Torque. But no TS.
There's the Mini VCI on amazon that's very cheap $25 but sometimes tricky to install the software. Need a laptop. It has TS.
There's the VXDIAG on Amazon for $77 that has TS. Need a laptop.

 

If you have amdroid phobe/tablet, you could also buy
- ELM 327 OBDII Bluetooth adaptor
- Torque Pro app
Cost less than $25.
You'll be able to read and clear codes as well as see some hybrid specific data.
Not as feature filled as Techstrem, but helpful for the basics.

 

There are two types of diagnostic devices to consider, an SAE J2534 interface and an OBD-II reader.
To use Toyota Techstream software, you need a device called an SAE J2534 interface or pass-through. Techstream gives you complete scanning and programming functionality. Techstream software is Windows only, thus the need for a Windows notebook PC.
For general code reading, you need a device called an OBD-II reader. OBD-II readers do not do programming.
They both use the OBD-II connector in your car, but have completely different command sets.

See this thread for details.
OBD-II and SAE J2534 Tools List for PC, Smartphone, Tablet; Toyota centric, July 2018

SAE J2534 interface devices are in section I.
Toyota provides the MongoosePro Toyota 2 MFC2 from Drew Technologies, number 2, in their Techstream LITE Kit, number 1, but they are expensive ($500 alone or $1345 for the kit of device + 1 Yr. subscription of software).

For a low cost SAE J2534 device, look at a Mini VCI, number 5 ($35) or 6 ($50).
For a little higher cost, look at the VXDIAG VCX NANO series, numbers 3 and 4 ($80 - $240).
(These come with the appropriate software).

For OBD-II readers, keep in mind that Wi-Fi versions are often easier to get working with an iOS device while Bluetooth will generally work with Android, although there are a few Bluetooth devices listed as working with iOS. Software for iOS is more limited.

Avoid the cheap ELM327 clones.
Devices listed as non-ELM, will not run the common ELM apps such as Torque Pro and Hybrid Assistant.

OBD-II readers are in section II.
OBDLink LX and MX Bluetooth devices are highly recommended, number 1 ($50 and $80). They work with the Torque Pro and Hybrid Assistant Android apps ($5 and $0).
ELM-327.EU ELM327 Bluetooth uses the genuine ELM327 v2.2 IC and is also highly recommended, number 2 ($57).

For iOS, look at -
OBDLink MX Wi-Fi, number 1 ($130)
ELM-327.EU ELMINO WiFi, number 2 ($64)
PLX Kiwi 3, Bluetooth 4.1, number 5 ($100)
K Solution LELink^2, Bluetooth 4.0, number 6 ($35)

Software is in section III.
Torque Pro, number 3 ($5) and Hybrid Assistant, number 4 ($0), both for Android, are very popular.
Torque Pro has a custom PID editor.

For iOS, look at -
OBD Fusion, number 5 ($10), can create custom enhanced PIDs, Toyota Enhanced Diagnostics Add-on ($10)
OBD Auto Doctor Pro for iPhone, number 6 ($23)
OBD Car Doctor Pro, number 7 ($4)
Car Scanner Pro, number 8 ($6), has custom (extended) sensors (PIDs) support for manufacturer specific data - unlimited active custom PIDs

 

Do the iOS apps come preoaded with prius hybrid specific codes like state of charge, battery block voltage, etc?

I know torque for android has it available, you just need to press a button to make them active.

 

I'm not sure, but I quoted some web pages below. I listed the iOS devices and software because I've seen several threads with people asking about it. Most devices in my list have links to their sites where someone could ask about hybrid codes or if the software is capable of adding custom Parameter IDs (PIDs) so they could be added.

OBD Fusion for iOS ($10) says the following:
"Settings are available directly in OBD Fusion. You can easily change adapter configurations, create your own PIDs, and edit your vehicle information." and
"Create custom enhanced PIDs"
There is also an add-on called Toyota Enhanced Diagnostics Add-on for in-app purchase of $10.

Car Scanner Pro for iOS ($6) says:
"Custom (extended) sensors (PIDs) support for manufacturer specific data - unlimited active custom PIDs"

Torque Pro ($5) has a custom PID editor which allows adding PIDs, which I assume is how it got support for the Prius.

 

For me, often customers are not comfortable adding custom pids. It adds an additional layer of complexity that many people do not want to attempt. Hoping to hear of an iOS app that has it preinstalled, or even just a quick option to activate hybrid specific data.

 

Could be a number of things.

Without knowing which codes are logged, it would be hard to say what the exact problem might be or where to look next.

Did you actually pay the Toyota dealer for the vehicle inspection/diagnostics, if so they should've provided paperwork with the needed DTC/INF code(s) that support their repair estimate.

Please post any known codes (DTC's) and any subcodes (INF's) for further help, without these codes you are wasting time (labor) and money (parts) without making much progress.

While waiting for codes... have you already physically removed and inspected each individual fuse/link. Though a long shot (since you said the inverter coolant pump is working), make sure you check the AM2 fuse.

 

Did you lock the orange interlock properly on the hv battery? Flip up and then push down to lock. Double check this item

Then reset your car by disconnecting the 12v negative for a minute. Try to start

 

Wow with battery safety interlock still installed those orange cables had 230 volts on them. They were hot.

You missed the most important step of the whole process. Really lucky you didn’t get electrocuted.

 

I think if you pulled the 12v negative, you should be pretty safe. The danger of leaving the orange interlock in place is if the car accidentally powered on, you could potentially get electrocuted.

Strange you get the same error after inverter replacement. That should have solved the ground fault info 614.

 

Will leave this here for reference:

2004-2008 Toyota Prius with code P3009 or P0AA6 and info code 526, 613, 614 | TOYO Headquarters

 

Harvest the new DTCs (with supported INFs) and post them here.
