This recently happened to me as well. I thought it was the LED upgrade that blew out, but XenonDepot tested them and said it was all fine. Im going to try the ECU reset tonight, ill let you know if it works.
Question
Your truck looks great! I am new to this site and to modifying my 4Runner. if you don't mind me asking, what was the install cost of the kit? or the time that it took? thanks
