How do i reprogram a used ECM if needs replaced?My boyfriend was hooking up stereo system and seems he fried my ECM??Inside lights and locks headlights all still work but will not start…
To answer your question, For programming a new ecm on a hyundai with out dealer tool you can use most any j2534 pass through device (I prefer drewtech devices)along with Hyundai's aftermarket j2534 programming software found at (https://www.hyundaitechinfo.com/).
I really doubt your ECM (engine control module) died, sounds more likely to be a blown acc/run fuse, bcm (body control module), or if equipped issue's with proximity key system. You probably should just take it to Hyundai or a qualified shop to save time and money before tossing parts at it.
