I have a 2009 g37x coupe with the issue of my cruise control not turning on after I got an up rev five map mail in flash tune… CODES: U1000/U1001…p1564…p0725…ONLY in a advanced scanner no CEL Attempts to fix: new battery, more grounds, new cam and crank sensors, new clock, spring, new steering wheel controls…..car runs fine, no cel codes, no dash lights AND the ecu and bcm register me pressing the cruise buttons but yet no illumination or activation… I just want to switch tune maps😭😭
