i just installed the factory alarm shock sensor and it works great. no problems with it arming/disarming and i have the sensitivity adjusted perfect. the problem I'm having is strange. when you hit the windshield to trip the alarm you can hear what sounds like the door locks do a rapid lock/unlock sequence, it sounds like tap tap tap tap, then the alarm goes of as it should. but it also does it when i shout the car off and get out, i shut the door and it makes the same tap tap tap tap from the door locks and the interior lites blink with the taping ( locks) but alarm dosent sound...that's without the alarm even armed yet, it does it when i go to get in the car too when i shut the door.. so what is causing this?

 

perhaps this is the wrong section to post this...

 

That wouldn't be good Did you try opening the door when it cycles?

 

no i havent tried opening it when it cycles because it does it fairly fast, as to as you shut the door its an instant TAP TAP TAP TAP. but ill see if i can do it tomorrow..why what are you thinking that would matter for?

 

There are a number of different ones of these..and the wiring is different...
could be wired wrong...

 

Yeah I would double check all your crimps and what wires you crimped. Basically just walk back through the instructions. I am embarrassed to say I caught myself. I had crimped the last one to the wrong side of a wire run.

If they are right maybe find someone through your local forum here and swap the unit as a test. Heck it would cost only a few minutes and a couple new zip ties.

Oh, could they put it in a worse area/position .

Take care,

Brian

 

Strange indeed. There are at least two different types, and I think one was for 04-05 and then 06 and above if I'm not mistaken..........and indeed the wiring was different.

Do you know which one you have?

There was a thread somewhere where we were discussing this difference about a year or so ago. I don't remember reading or talking about an issue like yours though. I think you got the best advice.............go through the instructions again, I know some people had grabbed one of the wrong wires. Kinda strange that it works except for the issues you describe.

I've got my old instructions if it comes down to that and I see you have an 05 car. I'll take a look at my old instructions and the wiring diagram of the car and see if I can come up with anything.

 

the instructions say its for a 04. so i wired it like the instructions say and i double checked the wires and there right

 

There's a DIY on the site for installing the OEM 04 anti-shock sensor. I followed it with ease. It's much better than the cr@p documentation you get from Mazda.

here ye go searche schalanged one.

Look for mysql's picture. His and the multitude of others will help.

 

yeah i followed the write up and the factory instructions and i am 100% sure this thing is wired right. the install was cake for me, im use to wiring entire EMS systems so this was nothing..and like i said the alarm functions perfectly, it just makes that strange sound (cycling of the locks) i also assume that if it was wired incorrectly, the alarm wouldnt function.

 

Most likely as you said.............................seems very weird though, but you already know that. I'll take a look in the morning while having my Java and see if I can spot any potential things that might explain what is going on.

 

cool thanks

 

OK i took another look at the car and i have more detailed info about the problem.. when you hear the tap tap tap tap sound coming from the door locks when you shut the door, the lock buttons near the inside handle doesn't actually lock/unlock it just makes the same sound it would if they were locking/unlocking. i also noticed that when it does this the (open door) light comes on in the gauge cluster. and to answer someones question in a previous post, yes you can open the door when its making this noise. it immediately stops the tapping when you open it. another thing is when the car is started it doesnt make this tapping when you shut the door...

 

It shouldn;t cycle the door locks when the alarm goes off....either the sensor is FUBARRED...or you wired it wrong

I have done 2 of these......they were a PIA..one was defective from the dealer..and the other was an 04 sensor they sold for an 05 and they don't work


...it is likely trying to trigger the horn relay....that would account for the on off on off noise.....does the alarm go off at all when you hit the car??

 

yeah the alarm functions flawlessly other than the strange sound. it even makes this sound right before the horn starts beeping when i hit the windsheild to trigger it. and also when the alarm isnt even armed. so if its like you said about it trying to trigger the horn relay. that wouldnt make sense since it makes the sound even when the alarm isnt armed. the instructions that came with it said at the top (instructions for a 04) but all the wires were the same on my car as they were in the instructions and the write up on this forum.

 

Get the dealer to call tech...and find out if the 04 sensor works on an 05....I know it doesn't on an 06......they had a batch of sensors that didn't work...so maybe you have a bad one....

 

Best to do that as I can't see anything in the wiring diagrams that would cause it by possibly having an intermittent short.

 

ok. what is the reason the 04 dosent work on the 06? i mean im assuming if my wires are in the same location and same colors as the 04 instructions i cant see any reason why the 04 wouldnt work. and like i said if this was the wrong sensor for an 05 i would think it wouldnt work at all, right?

 

sounds broke to me... either defective or the wrong version. I've got an 04 using the 04 kit and it doesn't do any of the click click type stuff you keep referring to.

It just works.

 

well this is where i bought it.http://www.finishlineperformance.com...cat=267&page=1 i figured a mazda dealership would know what years it works on but i guess not..

 

Talk this over with Tommy, he's a good guy there and should be able to help you out. He visits this forum and is.............."RosenthalMazda"

 

OK ill try to contact him. in the mean time i have more clues to the mystery. i shut my car off to day, pulled the key out grabbed my drink out of the cup holder and slid the cup holder lid shut, when i shut the lid the vibration made the sensor do the tap tap thing same as the doors do when you shut them. so its not just the doors its any shock that the sensor sees even when not armed, even if i take my hand and hit the dash it'll do it too so....

 

Do they still make this with the diode?
Is it mounted vertically?
And your sure it's not wired backwards...........although I don't think it could be, I'm just asking. Try turning down the sensitivity and then repeating what you just posted. Does it still do it? Oh......how did you initially set it.........the three feet tennis ball dropped onto the windshield?

All this is really BS cause it sure sound like you got a defective one, but I just don't know.

 

by diode do you mean the red light? yes that is mounted vertically. i initially set it by doing what the instructions said to do. hit the windshield with your palm hard it should go off but when you hit it lightly it shouldn't. then it was still too sensitive so i lowered it a little bit.

however it shouldn't matter where the sensitivity is set, when the alarm isn't armed you should never hear any sounds at all right? I'm thinking it must be defective...do you think rosenthal mazda will send me a new one?

 

The LED on mine blinks whenever it detects a shock that exceeds the threshold, regardless of whether it is armed or not. The only thing that is different is that there's no "system shock" that follows afterwards.
