    welcome! you need to have the trouble codes read. how many miles on her?

    you can either take it to a dealer, or buy a mini vci if you have an old windows laptop.

    some codes can be read by an auto parts store, but not all.

    anything is possible. you can get the mini vci on amazon or ebay. $25. or so, and see if it is compatible with your laptop. it may have viruses, so don't use the laptop for anything else. it contains the software for all toyota troubleshooting.

    10-4 Much ThanX " will do" i charged the aux battery & went for test drive & no dashlight symbols" may be aux battery" a few months ago i replaced 2 of the cells in the 200v battery & battery has been staying strong" so should eliminate 200v battery for the problem" The dealers around here charge way too much to just look at the car " $250 just to diagnose ?? they wanted to charge me $3000 for new 200v battery" when it just cost me $40 for the 2 cells"

    You're just taking shots in the dark until your Mini VCI shows up.

    All will be revealed .... :)

    There's no sensors on the brake calipers. Only sensors in that area are the ABS speed sensors on all 4 corners.

    Keep an eye on the brake fluid level because as you go super thin on the pads the calipers hyper stroke and use all the fluid you got. There is a low brake fluid sensor.

    It showed no codes because your probably throwing hybrid codes that the auto parts store reader cant decode.

    Ok "Much ThanX"
    Will Do" Thankyou" I really like this car" i will order the Mini VCI soon" i tested the aux battery& was 11.7v." I charged" & haven't had the red triangle & yellow ((!)) symbols come back on".
    Just changed my motor oil,last oil change I used a fully synthetic 5w30, went the recommended 10k & watched my 55 mpg go down to 44mpg towards the 10k". I just changed to a 10w40" went thicker, due to no oil leaks, yet loosing oil due to burning up through the rings with the lower compression from so many miles on the motor" just turned 270k,& now I'm getting 54-55mpg again" Is there a sensor for the compression in the motor? was thinking that could have been the cause of the red triangle & yellow ((!)) ?? i know shots in the dark" Much ThanX for your time & help is greatly appreciated"

    "ThanX" will get one soon" how many mpg do you get on your plug-in" ?
