2008 Gen 2 triangle of death, engine turns off, battery and other symbols light up

Wow that's interesting to see I have an '09 still a generation too and I've had every code in the book I've replaced the hybrid battery all that car runs perfectly but I have never seen that battery and that other icon over the top of my consumption meter and the green car which usually when anything is wrong that involves certain things that green car turns red but I've never seen icons over top of it interesting

 

It's all icons over top of it.

The "green car" is just part of the artwork of the usual MFD display pages, happens to be in the top left corner:



When it "turns red", that's a red car icon that pops up over the top left corner of whatever page is showing:



It's not the only icon that can show up there;

 

That's how I know there's something wrong with my 2009 but I have no idea what it is when I had all those codes and the ABS was messed up and blah blah blah my MFD never displayed any of that none of it The red car or the turtle has only been read when the inverter pump goes bad and that's it It might have gone red when the hybrid battery was down to nothing and we were driving the car to get a new one but my MFD has never showed anything The only warning I've ever gotten on the MFD is stop on the level surface usually because the door's open or something.

 

It's hard to know what Tom's posts are trying to say a lot of the time. LOL.

As to your issues, the battery icon on your MFD is the Charging system warning light. The other one (the car one) is the Hybrid system warning light. This would seem consistent with your inverter coolant pump has either failed or is running but not pumping sufficient volume.

If you want to check your pump without engine vibrations, the pump runs in IG-ON which you get to by pressing the power button twice with your foot off the brake pedal (from OFF). The movement should be quite obvious if the pump is pumping a sufficient volume.

Of course, obtaining the codes would be good so that you can confirm your symptoms. I'd expect to see at least a P0A93 which is set when the inverter has cooling issues.

I hope that helps.

 

That's correct because I have eliminated my standard inverter pump to a pump that may take a long time to fail so I may not see the turtle go red for a long long time I am not positive that that energy monitor green car or turtle turned red when the hybrid battery was in a complete crap state as in getting 37 mi to the gallon and the electric system basically not working at all as far as MG1 and 2 maybe regenerative braking and all was happening but it wasn't doing any good because the battery was shot it couldn't take the juice but I don't think the energy monitor was red All the lights were on on the dash and everything else was happening that's not supposed to but the turtle or green car remained green The only time I can remember seeing that turn red is when the inverter pump was failed not pumping and I was not overheating that inverter pump water yet it was still cool to the touch but because the pump wasn't running the light comes on the car turns red that's what I remember in my generation too this is all been very recently

 

Did you "check battery codes"? Most faults with the hybrid system would set codes in the Hybrid Control ecu or the High Voltage Battery ecu. Dr Prius is nice for what it does (viewing HV battery voltages), but is limited. It can read and clear engine & (mostly) HC/HVB codes. Dr Prius sort of treats HC & HVB as a single system and sometimes doesn't see alcodes correctly.

You would need a more capable scantool if you need to do more (or to work on other systems on your Prius)

I've noticed my Innova w ABS button . Reads all my P codes and my abs codes . I have tec stream but I've been using my Innova Alot no computer needed .

 

Yes that's better than mine so should do well .

 

I don't see the ABS button on this model. My lesser model has its red button . But this is same company . Mines a few years old

Here's a thread reviewing several scantool apps and OBD devices. The 4 at the bottom of the list will scan all systems on a Gen2 Prius for codes and data.

Another option is getting TechStream, the dealer's pc based diagnostic software + a Vehicle Communication Interface
cable. The legit way is to get a cable (can be several $ hundred) then buy a subscription ($60 for 3 days?) & download the TS software from Toyota and install it on a windows laptop.

There are bootleg copies of TS on amazon and ebay that come with a clone of a clone VCI cable. Can be sketchy to install and get working. All are hacked somehow to bypass the TS activation key.

You can search the Technical Discussion forum for "Techstream" & "VM" for a thread about downloading a virtual machine image file that has TS installed in it. Get a VCI cable, put Oracle VirtualBox on your laptop or macbook, and load the image file.
