I have a Evo IX with the OEM alarm, I just did a timing job a week ago and since then something weird is happening with the alarm. Before when I hit the lock the horn chirp once which is normal, now when I lock the car the horn chirp once and a few seconds later chirp again like when there is a door is open. I tried the basic setting like valet parking, disconnect the battery and others basic settings that are in the manual but didn't worked. I tested the alarm to see is it working, I'm talking about if someone try to open a door it will sound, also I tried with the trunk and the hood and it works perfect. The only thing is the third horn chirp like when there is a door open, but with all doors closed. Any ideas????
