    Are you still having that issue? My car just eventually stopped doing it after a while. I didn’t do anything to fix it either.

    Hey Pat nice to see your still around.

    I never mentioned one of my best friends back in the day was Jimmy Wong so every time I saw your name I thought of Jimmy.

    Jimmy grew up in Japan and went to Hitachi Electronic College. Got an excellent 4 year degree in Electronic Engineering. It was 100% free only had to work for 4 years in a Hitachi factory assembling TV's after college. Not a bad bargain. One of the best Engineering schools and a guaranteed job afterwards. Smartest electronics guy I ever met. We were very good friends.

    He owned an Electronic Repair Shop like me in largo Florida. Long gone.

    A terrible thing happened to him. He had the prettiest wife and 2 beautiful little kids. Owning a store they both owned and worked at really took a toll on there marriage though and they went to get divorced.
    In the middle of what became a bitter divorce he found out his wife had been having a long time affair with there attorney. An attorney Jimmy was using for help with the divorce. I can't think of anything worse than that. It tore him up and we lost touch. I told him he should go to the Bar about that as that's pretty damn dirty.

    So when I see your name I always think of Jimmy.

    Thanks for all your help. There are no codes, so I checked the coolant level and added some and then added very little to the inverter coolant reserve and lights disappeared and running fine the last two days.. Crazy but worked, will definitely consider changing that Inverter coolant pump, soon.. Thanks again for your help with this...

    Make sure you use an OEM PUMP not a parts store pump there a waste of time. I use Olathe Toyota Parts Online.
    The pump is really to get to the pump you take of the front bumper than your view of the pump looks like this.

    Its a really good idea to take the front bumper off anyway as there are alot of ground connections on the front chassis that tend to get corroded. Clean the connections with sandpaper and grease it up and bolt it back on.

    Aloha Patrick,
    After seeing your valuable input over the years in several threads on here regarding the ABS, VSC, and (!) Lights on dash, you are the Guru to best ask for advice. No codes on Zurich ZR11 OBD reader. History of how it happened. I replaced both front wheel bearings, brakes, radiator flush, ATF flush, oil change, and oil-engine-cabin air filter, fusible link, checked all fuses/relays under hood and driver columns, and have done the OBDII bridge pin reset which only rids of them momentarily. I can confirm the inverter coolant pump is running by double pressing IGN (no brake) and listening/viewing the reservoir turbulence. I DO however have a spare Amazon inverter pump for future case as it is prominent. I undertand the longevity won't be long but it's for emergencies. The battery is only a year old, and replaced a prior 2month old one, but I have just checked and it is sadly reading just under 12V with no load. That MAY be my problem (am trickle charging it now), but I'm afraid it could be more. The wheel bearings were practically welded on there and took quite a beating with impact tools and mini-sledge but I was as careful as can be to not damage the speed sensor, which would be another cause. Even wire wheeled clean the corroded gunk for the best fit. I've also read others solved it by a brake actuator replacement. I'm just stuck and pending the battery to be the culprit hopefully. Any other ideas would be a big help. Mahalo in advance.

    Forgot to add that it's a 08 Prius w/185k miles. No codes thrown. Inverter coolant level good. Clean battery terminals and ground connection.
