let me understand one thing,if I have the serial protocol in kline I have to connect the control unit on the kline of the mpps,otherwise canbus
if there is resistance to solder I have to solder

what I do not understand,that it changes from the read in boot mode to that in the serial??
why? if the block the edc15 with the serial boot mode I can resume it?
what has this mode? of cos? powerful?
