I have the same problem with my ABS light staying on after installing my turbo timer, and then using those directions to enable me to arm my alarm. Could someone please help? Thanks in advance.

 

i believe there is a thread for installing turbo timers on www.scoobymods.com for the blitz turbo timer, and although u have the apexi the problem u are experience should work. Since all wrx's come with the minimum of a keyless entry, that module detects whether or not the key is in ignition or something to that affect. Anyways, you need to cut a dark green/black wire in the keyless remote entry module located above the fuse holder which can be reached from taking off the panel underneath your steering wheel. Tell me if u need any more info, of maybe i'm just totally off track and dont even know what i'm talking about. But as far as not being able to lock the door, that should be the problem. And if you have the upgraded alarm, you would need to cut another wire location. but all this will be shown with pictures too at scoobymods.com Hope this helps
