Thank you to. IDK how many days I would spent trying to make this work, if not your help. And if only I always recheck any connections, it would be faster. So, I may say even more, cos of my "fails" - No charger connected or half plugged gives battery errors. - Brown wire to yellow, as dc-dc do...

Upd. Repluged charger/dc-dc controlling connector and connected SDW to DCSW through 1kOhm resistor, without dc-dc main board, and car say no error. Thanks very much. I hope that our work help somebody's else

Hello. I get 13.8 (battery voltage) on DCSW pin (white wire) when car tries to enable missing dc-dc, and there's no voltage on red and yellow wires

Yes, I mean DCSW signal. Thanks. I would try this on Monday and then write what happened after

Just 12v? Or battery voltage? So we have "DC-DC enable" 5 volts signal from car and "DC-DC enabled" 12 volts to car? I'm right?

I have i-miev with working(but not totally sure) charger and completely drowned dc-dc. Would like to install any other dc-dc instead, if don't find spare original one at good price. I feel totally stupid, when after making some CAN-bridges I start getting troubles with just some pwm signals or...

Hello. Thank for your hardworking investigating all this things. I would like to ask, is someone can read what going on sdw pin of dc-dc when it working? Is there just some logic voltage, or pwm, or even something more complicated?
