DONT DO THIS MISTAKE AGAIN. if ur ecu is fried, this means may be your mec, didi some wiring play or some other problem#
mostly ecu burn during service people when they throw water blindly
but i knew 1 guy who tried to do some wiring himself & got it burnt, again he bought new ecy from dealershil but just after installing it , he gaian burnt it, so then he took car to dealer , then they fix it
please contact hyundai direct, why it get burnt, they will giv u the correct reason
