P0B3B Honda CR-Z/Civic Lithium BMS Board Failures Update & Repair.

Well I have the four bad BMS boards 2xA 2xB back from my SMD solder volunteer and can report that three now work again after the LTC chip swapping. A 75% success rate which is pretty good. Two boards were fixed with brand new chips and two with reclaimed chips. One A board still gives an error but it's now a different one from before, so I think I will swap the other LTC chip on that board as well. Maybe reflow the other replaced chip as well. So it looks like the failures where one or more of the LTC chips has an internal voltage reference problem can be fixed by simply soldering in a new part. 00101110 $2E (46) Codes look fixable. 00110001 $31 (49) Codes look more tricky, not bottomed that yet. Details in the long thread on the CR-Z forum. https://www.crzforum.com/threads/lith...
