Newb here, so don’t trash too hard but...
Today I went to DCFC, and naturally I parked on the wrong side of the tower, opposite the Chademo plug. There was plenty of slack, so I lugged the cable over and plugged in, but after hitting ‘Start’ on the tower, it failed twice, “Transaction voided, disconnect the plug and try again...” Mind you, the cable wasn’t exactly taut, but definitely no slack. On the third attempt, I pulled a bit more on the restraint from the tower so the cable would be more relaxed, and it fired up without a hitch.
I’m not necessarily suggesting this is as a solution to OP’s issue, but It is something I’ll make sure to do from now on. As someone that knows virtually nothing about the inner-workings of these machines, I theorize that the little extra tension in the cable was keeping one of the com pins from making good contact...?
Anecdotal I know, but just my own experience.
