    P3019 question

    The code indicates a module #9 bank fault,

    Just curious does each bank have its own fault code?

    Thanks

    This indicates block 9, which consists of 2 individual modules. 1 of those modules most likely failed.

    Yes each block has it's own failure code

    Follow up question: Load tested Block 9 pair (18 and 19 from terminal end) and they both appear good. (quick drop from full voltage, then plateaus with a slow voltage drop, then when getting below 6v very fast drop). Similar to a good cell.

    Next step is to load test all, will update.

    Is the 3019 code specific to block 9 modules or is it for a range of modules? Any ideas are appreciated.
