1993 Toyota Pickup Alarm

Hello,

I have an alarm that the factory put in when I bought this in 93. For the last 8 years or so, I had it in valet mode. Last night, the alarm went absolutely nuts. Without being set, it started going off (which led me to think that the car battery went dead and the alarm was resetting.) Either way, the end result is that the truck won't start...won't even turn over(kill switch??). The headlights are the only thing with power. Tried disconnecting the battery to reset and put in valet mode, however it will not go into valet mode. Basically, I went to just disconnect the alarm. I am mechanically inclined (although in engines, not electrical) so I could probably figure it out with a little guidance. I am not sure what type of alarm it is. I believe I found the brain behind the left kick panel. The brain box has no name on it nut the keypad says MEDUSA. Can you help me please?

Thanks,
Bill

    In hindsight, that is correct...the dealer put it in. Either way, I removed it yesterday. It wasn't as hard as I thought. However, that wasn't the problem. Turns out that the main 80amp fuse blew. I replaced that and the truck will now turn over but will not start. I am going to check for spark and fuel here in a little bit. I am wondering if something else got fried with that many amps going through the system...

    Sorry, 15 amp EFI FUSE. Not relay.

    Look to see if your 15 amp EFI relay is blown.

    The MEDUSA is not a factory system. It was installed by the dealer. I would recommend that you elimate it completely.

I just bought a preowned 2006 Cadillac DTS and it came with the prestige alarm system after a couple of days my alarm would go off for no reason and when it does I would try to start it and it wouldn't...


This is what they are made for. To stop the car from running. Yours is aftermarket. Good ones last about 7 to 8 years.( your there). Eventually it will keep the car shut down. Your 2 choices are, to have it replaced, or just take the system out and repair any cut wires. Your car has a factory security system built in it. You'll just have to go out and start it manually.

What is the valet button located inside of glove compartment used for


It is used for programing the alarm, it is used to disarm the alarm without the remote, [in case remote is damaged] and it is used to put alarm system into valet mode, [service mode] valet mode is only really needed if the alarm has been programed for passive arming, [alarm arms itself].

Your main use for the valet switch, [if programed for active arming instead of passive arming] is to have a way to disarm the alarm if the remote does not work.

If it's the factory security system that honks the horn and flashes the headlights, you can shut it off by turning the key in the door cylinders or in the rear tailgate key cylinder. If it's an aftermarket alarm, look for a small silver switch under the dash and usually turning the ignition on and flipping that switch will permanently put the alarm into valet mode. Good luck.

Does not cherp


Is your perhaps alarm in "valet mode"? I've got a Checkmate on my Honda, and I can turn valet mode on/off by putting the key to Accessory, then pushing the black button under the left of the steering wheel. The alarm chirps when you switch the mode.

Can't locate Valet switch


Does the vehicle have an aftermarket alarm system? Is the valet switch for this what you are looking for? If so, it depends entirely on who installed it as where they have put it, although it's usually under the dash on the drivers side. Some alarms have different sequences that you have to go through to put the alarm into valet mode, it's not usually just a switch that you flick. Best to pop into an alarm or stereo installer and see if they can spot it for you, or if the car is immobilised, find out what sort of alarm it is and call an installer for the info on the valet procedure.
Hopefully i haven't just wasted my time and yours, but i can't think of any other type of valet switch, and your description was pretty minimal. Cheers, Mark.

Factory alarm


Sounds like it has an after market alarm in it? Some times you can unhook the battery and then put the key in the ignition and turn it to the on position and them hook up the battery with the key on and this will clear the alarm. If it is a factory unit you may be able to use the key in the door locks to shut it off or try the same thing as the aftermarket reset.Don't short anything that can fry things. If it is a factory alarm with keyless entry, you should buy a key fob and program it and avoid future problems. You can program this by cycling the key on and off either 6 or 8 times, ( can't remember) and the door locks will lock and unlock on thier own to let you know you are in program mode push the lock button on the remote and it will lock and unlock again to let you know it is programed. Hope this helps....Dan
