OK, I been standing on my head under the dash on the drivers side of my 2000 Tacoma Pre-Runner, after fighting with my alarm. My battery has been disconnected for the last 3 months, and now I'm trying to get things going again. I can not reset or disarm with the key fobs, the originals, with good batteries in them (I got a 5 pack of the little 12 volt batteries for them). I can disarm by turning the key to on (not start) and pushing the red button on the dash a couple of times, but if I open and shut the door,(nothing else) the red light on the dash blinks real fast for about thirty seconds, then the horn beeps once, the lights flash, and the alarm is armed again, and the only way to disarm it it to do the key to on/red light button thing again. Key fobs do nothing.
I want the alarm GONE, or working right. This truck will be having the battery disconnected and reconnected a lot in the next several months. I followed the wire from the sensitivity box to another box that says "Main Module" and "Part # 00014-S0200" on it. It has a fairly big molex type connector also on it. Is that the alarm? Does anybody know what's wrong? Does anybody know how I can make my alarm inop completely? I don't care if I have to lock and unlock the door with keys/hands. Please help Tacoma alarm experts out there.
