Just for info, im looking at one here: no codes & using a japanese s/w programme to code read, LAUNCH x431 upto date s/ware, you wont get UK TOYOTA import support as IMPORTS are not for this country if that makes sense, hence peopls saying toyota could not read etc.
I'm still to look at live data values to see what the tool covers.
Ref: DISCONNECTING HYBRID SYSTEMS - after removing ORANGE HIGH VOLTAGE CONNECTOR WITH HIGH VOLTAGE GLOVES, after the waiting time you should also be carrying out voltage checks wearing HIGH VOLTAGE GLOVES & use a meter capable of high voltage reading and making sure you carry out AC & DC VOLTAGE checks correctly. . If the capacitors have depleted by the waiting time, you wait again.
If unsure of what you are doing, dont be surprised - if you change/replace and then go to your local toyota garage & say please reset lights etc, they may say no etc.
