I purchased a 1997 Tacoma a few weeks ago. I noticed the red LED pushbutton on the dash, just left of the steering wheel, and the "security system" sticker on the driver's side window, but the previous owner didn't have any clickers, and told me he had never used the alarm system.
Well, last week the truck stranded me at work -- I turned the ignition to start it, got a "click", and nothing else. Went to check the battery connection, opened the door, and the alarm went off. I popped the hood and disconnected the battery. The positive battery connection was pretty loose.
My theory is that the loose battery connection set off the theft protection, so when the battery made momentary contact again the alarm went off. I got a ride home, then returned the next day and pulled the alarm brain. The truck started right up at that point.
Pulling the alarm brain, however, has made the power locks act a bit funny. The driver's side lock button only controls the passenger lock now -- the driver's lock must be pulled up and pushed down manually. It's also stopped doing the automatic lock-unlock process when the truck is started and then shut off.
I'd like to plug the alarm brain back in, but I don't want to mess with it until I have a clicker. I've read that the southeast region/gulf states trucks often came with different alarm systems than the rest of the country.
Can anyone identify this alarm system, and point me toward what kind of clicker I need to get for it? I know the pics are terrible -- I took them quickly with my cellphone. I haven't yet pulled off the adhesive pad to see if there is more text underneath that might be used to identify the alarm, but I can do so upon request.
