The flex cable carrying VB2_ON and connections are OK, confirmed...
Then I cut the VB2_ON track, and shorted ICPWR3 pins 1 and 2.
Output (pin4, TIN) went HIGH... but TOUT remained LOW. And according to
LV8013 data sheet, when EN and TIN are HIGH, TOUT should also be HIGH.
There is another strange thing with this LV8013... it has charge pump, output from it is ~13V, but motor is definitely powered from battery (via _-MOSFET that I had to replace earlier as faulty). At this moment, I am not sure where this voltage is used, and I can't imagine someone just blindly followed the data sheet and left all recommended components on bard, only to use only a fraction of the the functionality of the IC.
