02 solara sle doesn't beep when alarm arms or disarms

[02slera]

what color are the wires on that connector you found?
i did some looking around at my car again yesterday and after removing the front passenger turn signal lamp i could see a harness ran through the fender, i noticed there were plugs going to the washer fluid tank (one for the pump and one for the level sensor i think), then i noticed two wires that were cut (my car was wrecked before i bought it), the wires were green/red, and white/black. the second color is the stripe. But i also connected a extra bulb i had across those wires and hit the lock/unlock buttons and the bulb did not light. (i put the same bulb directly across the battery and it is a good bulb), it seems that if the wires i found were meant for the buzzer then i would have seen the bulb i rigged up flash if the 12v was applied. im almost to the point where im just gonna buy the buzzer and wire it into the turn signal. the front passenger turn signal has 3 wires, when i put my test bulb across the green/orange and white/black wires it lights with the lock/unlock flashes but not with the turn signal or hazard, so if i wire the buzzer into those two wires on the turn signal it should work fine.

that connector on my car has the same wire colors as your cut off one (red-green and black-white).
make sure your car has enabled beep sounds in buzzer and re-test, maybe your car alarm now is in disabled buzzer mode?

i disconnected the battery and then reconnected it, my understanding is that this will default the system to where it does beep. there is still the possibility that something else is wrong and the buzzer (if it was even there) is not getting a signal to beep. i am going to buy a piezo buzzer and hook it to those wires, i do believe that is where it is supposed to be. but if that doesnt work ill just do like i said in my last post and rig it up with the green/orange turn signal wire.

EDIT: looks like i'll be buying a M-80W piezo alarm here: http://www.floydbell.com/ for $21.06 shipped.

bought the buzzer off ebay for $15 shipped (used from Lexus IS300 - power slide door buzzer - with same Toyota p/n), plugged that into my plug and now alarm beeps

[02slera]

^^^ i should have checked ebay.
i ordered my piezo alarm and i am STILL waiting for a confirmation that is been processed/shipped that floyd bell website is not looking good right now.

yeah I was lucky with it. a fellow TN member pointed it out to me (he's trying to make his '99 Avalon alarm beep as well) right before I placed the order with one of Toyota parts online dealers. saved me a bunch of money. also shipping from that ebay seller was super quick, I was really lucky

i got my peizo, i bought the "continous" beeper because i figured the the car would pulse the 12v when needed and make it just beep once or twice. but i have a constant 12v on the wires and when i hook up this beeper, it continuously beeps. i dont know if buying the original oem part will work or if my car has a bigger issue. anyone have time to put a meter on these wires and see if its a constant 12v? that would help me alot. if its not a constant 12v, then is the green wire (+12v) switched? or is the white wire (ground) switched? in other words is a ground applied to make a beep or is the 12v applied to make a beep? the last option is that the 12v is supposed to be there all the time and when you hit the button is creates a pulse that tells the piezo to beep. this is the one i hope is correct because that would just mean that i bought the wrong beeper.

so it turns out that the turn signal wire i was looking at tapping into will not work properly.
the beeper will beep when i want and does not beep with the turn signal or hazard, but what i didnt expect is that when i turned my lights on i got a constant beep haha. so this beeper will have to be wired into the place it belongs. now if i can just figure out if im supposed to have a constant 12v to this thing or if its switched AND if it is switched, how? the ground is switched or the +12v is switched? damn.

I would check the voltage at beeper socket on my car, but the weather is terribly crazy here and I don't have a garage...

so what happens when you attach the beeper to its correct socket?

[02slera]

if the weather clears please take a few minutes and check for voltage at the plug with the beeper disconnected.
i read 12v constantly and im thinking maybe it should only get 12v when you hit the button and it is trying to beep.
when i attached the beeper i bought to the wires it immediately goes into a constant beeeeeeeeeeeeeeeeeeeeeeeeeee....p
and im not sure if its cuz i bought a random 12v beeper and i need to buy the factory one, or if my car has just got more issues and i should not be getting that constant 12v. but even further, if you have time, if you do not have a constant 12v at that plug can you see if the ground is switched on/off or the 12v is switched on/off. easy way to do that is check for continuity between the white/black wire and a known ground, my car has constant continuity there so the beeper is getting a constant ground throught that wire and a constant +12v through the green/red wire.

hmm, I would check your wiring again. it sounds like ground wire is shorted to chassis, before signal reaches alarm ECU further. Toyota electrical systems usually activate/energize devices by switching the ground on/off at the ECU (or a switch).
unless this circuit is different, but then I don't see how it would be able to activate buzzer when needed (door lock/unlock etc).

I will check the voltage and resistance for you, no problem once the weather clears/warms up. We have a damn cold one now, well below freezing constantly and getting as low as around 0F (winds effect counts too) after sunset. once it goes back up to high 30s I will.

[02slera]

thanks man. i know what your talking about with the cold weather, im in virginia, and even here it's damn cold. and i agree i think the ground should be getting switched and is probably shorted out, i had a little trouble following what you wrote though, you mean the wire is probably shorted to the chassis somewhere between the alarm ecu and the buzzer location? < thats kinda what im thinking. and if under normal conditions you do not have a ground at the beeper this will further verify what is suspected. and after that i will test the wire at the alarm ecu, and if that checks out, then run a new wire if i cant find the short. but one thing at a time.
speaking of the cold weather reminds me, be careful, a couple months ago my door was frozen shut and without much force at all i broke my exterior door handle (plastic) (-$80.53).

yup, that's what I meant.

I should be able to check it for you during the next weekend if weather forecast holds nice.

thanks for a tip on frozen doors and handles.

[feniks]

02slera, I did the checks for you.

first of all this system is unlike toyota's circuits.
I also have ground wire (black-white) continuity to ground point at all times.
there is no continuity on +12V wire (red-green) to ground wire or ground point ever.

the +12V appears on red-green wire to show only when pressing remote buttons, besides that it reports 0V all the time.

sort of a hint (not quite, but still something), buzzer beeps all the time in my case only when alarm tries arming and 1 of monitored doors stays open (or sensor is open).

[02slera]

ah the hint may very well help, now that i think about it i believe i had the hood open when i was trying to install, perhaps i just need to try again with the hood closed. i already know that the hood is monitored because one time i was working on my car in my garage and the hood was popped but still down and after 10 minutes or so i went to lift the hood and the alarm about gave me a heart attack. Thanks for taking time to check the voltage for me. It really helps me out a lot. ill post back after i try the install with the hood closed.

Edit: no luck. i have a constant 12v and i cant figure out why. thanks again for the help though.
