sheiksoft your lowest modules seems to be 8 and 9. like Nacke mention might be either one or both cells in the modules got to strip the cover and test each module. a time consuming process. you will need some cover to work away from rain and dust and lights if going to work at it in the night. try to be careful with the tiny screws for the cover. thought i lost one under the passenger seats. luckily was stopped by some cables and i could pick up with my screwdriver with a magnetic tip.
need
8mm
10mm
12mm
sockets and a ratchet to make things easier.
remember to remove the orange safety switch before opening up the battery otherwise is 200volts.

btw, how to find out which modules are 8 and 9 physically.?
Also, once I get the modules I can replace them with the bad ones, right.? No need to charge them or boost them.?

Finally got the new modules and replaced it. Could only took snaps which I will post it soon.. My bad, when working with HV Battery I was wearing a metal watch and accidentally came into contact with the modules, the watch broke apart with heat. I got hurt a bit.
Replaced the modules with the faulty ones. So far so good. I am periodically checking the Data list via toyota techstream. Will post the pdf's and images for reference purpose soon.
Thanks Guys for helping me out. Thanks a Lot. Club Lexus Rocks.!

1. P3018-123 Battery Block 8 becomes weak
2. C1259 HV Control System Regenerative Malfunction
3. C1310 HV System Malfunction
Do I have to order few more cells again.?
Please help.

Thanks for your message. I touched the modules which are in the extreme end like 13 or 14th block. After a week placing the order of 4 modules, I saw 2 blocks are low along with the ones which I thought of replacing. So I have to change 2 more blocks maybe.
