    Hey everyone so my 2006 prius suddenly had all these lights turning on the other day. At first the master triangle red light turned on as well but turned off now. Also my tire pressure light is on due to what we think is a bad sensor but its been on for awhile and i think it's irrelevant to this current issue. What do I do?

    I've tried testing the 12 V and from what I'm seeing it seems normal so now I'm at a loss as to what else to do.

    Car is running fine.

    First thing to do is get the trouble codes read.

    You need to use a mini VCI cable to read some Toyota specific codes.

    the red triangle turned on then went back off----check your oil and see if it's low

    While the Prius is READY, look at the inverter coolant reservoir for fluid turbulence. If you do not see this, the inverter coolant pump has failed.

    Since you see the VSC, ABS and ((!)) warning lights on, the skid control ECU definitely has logged DTC. As previously suggested, use Mini VCI to retrieve those.

    Toyota is out of these inverter pumps. You'll need to get it online somewhere

    Did do as Patrick said in Post #7? Verify that you see or don't see turbulence/fluid movement in inverter reservoir? If no turbulence/fluid movement when the car is IG-ON or READY, the inverter pump is dead and needs to be replaced.

    Many posts on how to replace.

    If you have not done the recall, the repair would be free. However Toyota is out of these pumps, you'll probably get a free rental until the repair is completed
