    My daughter bumped her 2006 Prius into an SUV in front of her. No one was hurt. The hitch of the SUV penetrated her grill and caused radiator to burst and damage to condenser. We've replaced and filled radiator, replaced condenser, and compressor, and charged AC. Car would not go ready and all lights on. Inverter Coolant was empty. Filled coolant. Restart and car cranked. Drove down the road but lights remained on. The hybrid battery is showing charged. The 12V battery is fairly new and putting out well over 12v. Inverter coolant shows turbulance. Resetting the batteries allows it to go to ready, but happens again when turned off.
    There are no codes showing but all lights are on. In diagnostic mode, all shows OK. I've read about air in the lines. We didn't pull a vacuum initially. Any pointers on where to start? She doesn't have money to take to dealership. Trying to fix it for her at my home shop.

    Or, if not Techstream, what are you using to read trouble codes? It doesn't seem to be working. That will slow you down.

    I do not. I read on a thread to buy a mini VCI and techstream on Amazon or Ebay. Then, I read where the software had loaded trojans on the computers being used. I wasn't sure if it was a good idea or not. I suppose it's still worth a shot. This car has been a daily driver in our family for 12 years and we purchased a new 2015 Prius V 7 years ago. It will probably be worth the investment since we have two hybrids.

    I have been using an older OBDII scanner. In the past, it has given me some codes, but nothing now. Since we have two Prius Hybrids it is probably worth investing in one that will read the codes. Do you have a suggestion? I read online that some suggest the mini VCI and techstream from ebay, but others claim it loaded trojans on their PCs.

    When we reset the lights, the Prius will crank and run with no problems and no warning lights. If the A/C or heater is on, it runs less than 30 seconds before lighting up the RTOD, ABS, VSC, traction, tire pressure, engine check and the red car on the MFD problem light comes on. The 12v battery was recently replaced and voltage seems OK. Hybrid battery appears to be charged, but it has fluctuated at times according to the display. I assume it is from sitting and not being driven.

    I got POAA6 but can’t get the detail to narrow down the source.

    if you don't want to try tech stream, you'll probably have to take it somewhere.. maybe you could find an old laptop to load it onto

    Thanks. We decided to take off the compressor and put the old one back on to see if it made a difference. Pulled a vacuum and filled. So far, no codes have been thrown. All lights are off. A/C is cooling. Hoping the compressor we put on was just bad. Thanks for all of your help.

    I am having the same issue with all the lights and it not cranking unless i reset the batteries. Mine happened right after my 12v battery died. What did you do to fix your issue? Just replace the ac compressor? I have the BT obd2 reader

    Yes. Installed the compressor we had taken off (assumed it was bad from wreck) and it went away. It was fine.

    Best thing for @Stevie D's different car and likely different issue is to read the trouble codes, and determine further steps from there.

    Replacing the A/C compressor would be a fine fix if Stevie D's car by marvelous coincidence is reporting the very same codes for the very same reason as deegee's ... otherwise it would be an expensive distraction with potential to introduce new issues.

    My sons 2006 had a similar issue but it turned out to be the 12v battery. He had about 2 inches of water in the 12v battery compartment. We drained it (there is a rubber plug on the bottom) and used silicon to seal inside the hatch just above the brake light area. Then I put a brand new 12v in and initially it acted the same so I disconnected the 12v and pulled the hybrid battery quick disconnect and went to bed. Plugged everything back in the morning and back to normal!

    This is turning into another one of those threads where (so far) three different people having completely different issues with their cars are tagging on to the same thread just because of which dash lights they see (which tells very little) and not knowing what trouble codes they have (which tells that they haven't used scan tools that can show them).

    Getting the trouble codes, which ought to be near the first order of business for warning lights on a Prius, would quickly reveal the differences between unrelated issues like these.
