The modules are completely silent, so that's worrying.tom91 wrote: ↑Tue Nov 07, 2023 12:29 pm If savvy can is on the bus with the modules and the BMS which ids are present? all modules broadcast a "status" regardless if they are being requested by the BMS.
There is a possibility you messed up you CAN wiring. lacking termination resistor could be an issue it does not have to be.
Possible I messed up the canbus wiring but it's the original BMW loom that was working before the experiment, so I'm not sure how. I've been through it all and tested for continuity and shorts.
Failure of the 5V supply or ground would be the obvious answer but fairly confident I've ruled that out. I'm going to check again though because that's the only thing that really makes sense to me.
