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

Oh yeah I guess a scanner can't find or talk to the immobilizer is what the guy said too I'm just stuck it has a AP on a stage 1+ AEM tune it was on a stage 2 bout idled rough and wanted to die at stop lights so I did all that work and fixed but brought more pain my way

have you tried locking/unlocking (actually, setting/disabling the sec. system) with the fob a coupla times?

Yes I have I don't understand how this happened some told maybe a brake switch sensor but idk

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.

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
