Yellow Triangle Of Death

Hey everyone,

Currently out of town on a road trip and my 2012 Prius is acting funny. Went to autozone to check the odb port and get a code because the "stop check hybrid system" with yellow triangle indicator turned on, precided by a check engine light that came on and off yesterday. When the autozone tech plugged into the obd port with two device we did not receive any code like I was hoping, only a engine is not running message even though the engine was in fact running. Then the warning lights turned off. Any guess as what it could be? Had the main battery back replaced last summer so shouldn't be that. Maybe battery fan?

 

Hey so I did just refill the coolant reservoirs on both sides. I am not sure if the inverter pump reservoir is moving while I am stoped. If it is, what does that mean? I haven't replaced the 12v battery in awhile.

Yes, the problem is it is Sunday and most shops are unfortunately closed. I will check the 12V battery, maybe it is starting to go bad?

 

It was refurbished, I do not think it is all new. I am not completely ruling it out, but it's only a year old built by a phenomenal company. If it is the larger battery, it is warrantied.

 

I honestly could not see any movement. However, it has become obvious I have a coolant leak.

 

It's okay, I will figure it out and get it fixed. Thanks for all the help guys.

 

Not that many, 178k.

 

That is true, however I am not hearing any engine knocking or rough idle as of yet.
