New to the forum. Getting Red Triangle error light and others, ABS, VSC. The car won't go into drive or reverse, or activate the ICE. I have replaced the inverter coolent pump and it is working. The thing is when I plug in my OBD II code reader no codes are found. Has anyone seen this before? Any ideas on what it could be? I am still learning about these Hybrid vehicles. This is my second gen 2 Prius. The first my son ran into a palm tree so now I have a parts car. LOL.
You need to get a code reader that's capable of reading Prius codes. There are definitely codes stored. Did everything start and run fine before you replaced the inverter pump?
