Triangle of Death appeared today...

I just checked the Inverter coolant and in ready mode - its not agitating or moving at all, not even a vibration from the walls of it. With a flashlight - I don't see any coolant leaking, and the levels never really changed dramatically - so my guess is the pump needs to be replaced.... and that should solve the P0A80 issue too.

Because via techstream I am not getting a listing of any cells being weak.

Where in the past, when I did get the battery modules worked on... I did have codes saying that I had dead or weak cells ( P3018).

So maybe there is hope after this pump gets replaced. I'll call the dealer for a price on the part... seems that the autozone / aftermarket versions are not that great - based on some other threads I been reading today. Or maybe I am wrong.

I went and checked my Accessory battery charge

and its hovering around 12.3, I replaced it 2 years ago as well.
I have no idea the longevity of these batteries or what to expect - but 2 years of light use - cant be that bad.
14.3 Volts in Ready mode too.

Which, again lifts my spirit that this issue is just the hybrid coolant inverter pump needing replacement. I hope so.

Since we are here... I assume a water pump issue is a completely different beast?

Thanks for your reply!

 

The screen is showing plenty of bars on the hybrid battery. I guess one issue at a time... and I guess it will be the pump repair first since its not agitating the coolant at all. After thats done - I am considering clearing the codes, driving it and seeing if the P0A80 will returns.

 

Essentially the graphic is useless, I guess? I'll run codes after the pump is replaced.

 

Noted, thanks for all your help. Hopefully finding parts will not be a issue. Thanks again.

 

Yes, Jim - if we could get together and diagnose this beast that would be great. Hope you are doing well - Never bothered changing out the capacitor. it's an intermittent issue, and only one time we ran out of gas when didnt realize that this would cause the reading on the gas gauge to be wrong - so my girl just fills it up once a week if it needs it or barely not. Hilarious. Scroll up to see my new issues.

 

Todays update:
After replacing the invertor pump ( toyota parts $163, via rockauto and some credit I had there) It was not that hard of a job, I tried to be as fast as I could installing the new pump - but did lose fluid. So it definitely will need a bleeding. I added to the full line but I am sure that will go up and down as I bleed out the bubbles.

-- I didn't bleed it yet --- I put it through techstream and I am not getting P0A80 error codes - but it is marked as pending.
I'm going to do the bleeding tomorrow afternoon... test drive, and tech stream it for codes.

As of right now - We took it on a 25 minute drive - out of curiosity if the Red Triangle would reappear; and no warning lights appeared. I didn't tech stream after this drive.
My girl drove the car briefly to the grocery store less than 4 miles away and the check engine light clicked on - but not the triangle of death. I just ran techstream on it:
I have a few generic codes - B1421, B1271, and P3000 -- the last one probably because of the non bleeding.
P0A80 pending I am researching to confirm it takes 40 trips to clear it out of pending.. and just one more error read to move it to current... and a Red Triangle of Death? Hopefully, a bleed will resolve this.

 

P0A80 is gone - no longer pending, many subsystem had zero error codes to report. the battery is charging higher than it did previously, now at 16V instead of 15V yesterday. The gas engine was shutting off and turning back on at idol quicker than before, and the arrows on the dashboard computer make sense.
Only code was the solar panel thing for the a/c unit.

Lesson learned here was that bleeding out the bubbles for the inverter cooling system is a very important step. It was easy to do, I should have just done it the day I installed the new pump.
