Coltjack Posted May 13, 2018 Share Posted May 13, 2018 Hey guys so my 2009 WRX won't stay running it'll start for a few seconds the die like I turned the key off the the security light constantly stays on after the start it's not on before tho. Icar throws a code P1572 I had the keys reprogramed well kinda the matched up to begin with that didn't help. Btw this all started after I disconnected the battery to clean the MAF and the check for vacuum leak's cuz I was throwing a code before that fr being to rich and I did have a hose disconnected from BPV to the throttle body so anyways got it all back together car sounded good ran good well for a little if I WOT it would cut out then back in CEL would flash I thought maybe the ECM was relearning the it just stop running All together and I've researched everything i could. So here I am looking for help and a second opinion Link to comment Share on other sites More sharing options...

GeneralDisorder Posted May 13, 2018 Share Posted May 13, 2018 1572 is an immobilizer code. Either call out a locksmith or take it to the dealer. Those are the easiest ways to get that fixed. GD Link to comment Share on other sites More sharing options...
Coltjack Posted May 13, 2018 Author Share Posted May 13, 2018 Called a lock smith last night the key didn't need to be reprogramed he said everything matched. Then digged a little more with his programer and said he could access the immobilizer Link to comment Share on other sites More sharing options...
