2007 Gen 2 Prius Red Triangle, VSC, (!) dashboard lights! help!

The codes you have relate mostly to engine issues. Most are from the engine control module. One (the P3190) is from the hybrid control module, referring to an engine problem. The brake control module will respond to problems reported by the hybrid module.

Your list of codes doesn't include any brake code. It should, because those lights are on, so most likely you are using a scanner that is not retrieving the brake codes. You should find out what those codes are (though it is possible they will just be the "look your hybrid module has codes" codes, which again would be secondary to the engine issue).

If you didn't read the original codes that were the reasons for the lights to be on before you replaced the actuator, then we also don't know what the original issues were, or whether they were major, or whether there was any need to replace the actuator. A job like that, which is involved enough to run the risk of creating new issues, isn't one I would recommend to anyone unless the evidence clearly requires it.

 

How are you checking/maintaining the coolant level, as there is the radiator cap (preferred method) and the coolant overflow tank.

 

Have you noticed any leaks under the vehicle?

When was the last time you check for a leaking water pump, or had it replaced?

Check the dealer vehicle maintenance history by entering your VIN at : https://toyota.com/owners

Like @ChapmanF mentioned, the scanner you're using isn't fully compatible with a toyota hybrid. You still have unreported DTCs.

Many prefer using a mini-vci cable and a copy of techstream (same software the dealership has) for regular OBD2 scanning. Though not as good, you might also try a OBD2 adapter and either of the "Apps" : Dr Prius (Dr Hybrid) or Hybrid Assistant/Reporter.
