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...

    That was it.....thank you.

    Sorry, 15 amp EFI FUSE. Not relay.

  • Toyota Ed May 11, 2010

    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.

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.


CAR ALARM ISSUES


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

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.

I had to change the battery. After replacing the new battery all systems work, but the car won't turn over and the factory alarm is blaring. How do I disable the factory alarm? I do not have the...


Hi,
If you have the Toyota factory alarm, there should be button under the driver's side dash to reset the alarm....Look for it 1st, then read below.

Put the key in the ignition, and turn forward
all the way just before cranking, to the ON position.

Then within 5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

At this point, the only thing working would
be the keyless entry from the alarm,
if it came equipped that way.

Just Repeat these steps to place it
back to usable armed mode.
You may get 2 chirps, confirming it,
and the lights may flash twice as well.

GL,
Td

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.

1993 celica alarm goes off all the time


Well what I would start with try setting the valet switch...Every alarm has one the trick is finding it... I would look by the fuse box for a little toggle switch, this is where it most likely will be ... you can activate the valet by flipping the switch and turnining the key.... If you have an L.E.D. that blinks when alarm is armed this light should stay solid...Activating this switch will override the alarm so removal will not be necessary... Good Luck
