Hi Chris You can buy a cheap Chinese OBD2 cable that cost less than 20$ on eBay, it called "mini vci" With it you will be able at least to see the versions of your ECU software, and not only, you will be able also to see like all the parameters of engine, battery and much more. But this cable cannot reprogram, for reprogramming you will need at least a MFC Mongoose cable that costs near 500$ The Techstream you can download for free on official european Lexus service website .

^Για σου μιχανικέ :) In GS450h made of 2006-2010 it's a ECU software problem which kills all the modules of battery! a official update exist, i already updated mine especially for that procedure i bought a MFC Mongoose cable that costs 500$, but i did it too late when the battery was dead already, i has the P0A7F. I measured the capacity of all modules, the side modules have about 5Ah as it goes to middle the capacity is decreases, the middle module have 1Ah capacity left... The document which comes with the ECU update it says the new software prevents the HV battery from overheating, my capacity shown exactly that this happened from overheating since in the middle they heats more and the middle are the weakest modules! So with a P0A7F don't expect that you will fix your battery with changing few modules, 95% of battery is junk with that DTC. Alex.
