355: 4 beeps when arming alarm. where is the fault?

According to the manual. ..4 beeps means "something is still open"...like a door or an engine lid or hood. All shut of course.

Once in a while it only beeps once as it should. ..but then the alarm will usually go off randomly. wow is it loud!

Anyone else have this or solve this? Ive tried to check the sensors on the hood and engine lid. ...but no luck.

It might t be the passenger door. It sometimes beeps only once when i try it after my passenger exits.

 

You'll have to talk to the alarm with an SD tester.
Are you near North Jersey (Tenafly)?

 

Im in Ocean County. I guess an sd tester searches the alarm ecu and could find the fault?

 

It's been a while so I hope I'm thinking of the 355 alarm but it should give you a list of the last few faults.

Whoever you use for service should have an SD so they could look at it.
If not, if you ever find yourself in North Jersey stop by the shop and I'll look at it.

 

thanks Mark. Where are you located?

 

What was the final result on this thread???

My car is back from it's major and my alarm is doing the 4 beep dance now.

I pulled the switches out of the doors and they all work, leads are clean and contacts good.

Boot & trunk latches have been tested and all acting as they should.

I pulled the leads from the alarm ECU and cleaned & tightened them...one by one. Ugh.

I pulled the lifting device and cleaned it as best I could but not sure how to test it. Four leads on the Bosch unit and I would think I would get an ohm meter to show me a closed contact...but I have none.

Close it all up and arm the system: Light + 1 beep, pause & 4 beeps. ahhhh.

Any other ideas??

 

Wait, 4 beeps isn't normal?

 

Could be a hood or trunk not fully closed

 

From the manual:

System not "armed" correctly due to an incorrect access (open doors, bonnet and hood, faulty switches):
1 + 4 flashes + siren beeps.

Disarming after theft attempt (the system signals that one of the accesses has been forced and the siren has beeped) :
3 flashes + siren beeps

 

Thanks, but not only did I ohm them out, the car runs the F1 gears fine...and it will not do that with the hood or trunk open. Latch & Door switches check out as fine.

 

Nope.

Normal arm = 1 chirp - 1 flash

Normal disarm = 2 chirps - 2 flashes

The rest courtesy of Eitan:

 

With the system armed, jack up the side of the car as if to change a tire. That should trigger the lifting device & alarm (at least the one in my car does.)

 

Great suggestion.

I am too lazy for that much work. I have the inner front clip out so I just leaned on the sensor.

Weird in that it triggered the lights, but not the siren.

 

My f1 beeps i think 4 times if i lewve it in neutral. My passenger door if its open the alarm will not lock the doors when it beeps 4 times. I have levt the pass door open even though it looks closed. About 1/16 inch diff between closed and open.

 

So no flashing alarm light on the dash when driving? In my experience if you lock and unlock the car with the fob and do that a few times without driving the car it will beep 4 times.. Unlock it,drive it around then lock it,seems to like that and beep once etc. I have a new GM alarm siren and works perfect.

 

Any update on this ?. Was it the anti lift unit or door switches or something else ?

 

Yah, I'm still stumped. One out of ten times it will chirp once.

If it chirps 4x, usually the alarm goes off within the next 5 minutes or so.

I always have to lock the car with the key.

I guess we are all waiting for that one person to figure out the elusive fault, since my car has no plans to be in the $hop anytime soon. When it comes to electronics and wires....yeah, not my forte.

 

Check your doors and make sure they are fully flush when closed.

As i said above allthough the F1 system is NOT supposed to know when a door is not fully closed my F1 will still work when a door is mostly closed. This leads me to believe that the alarm also knows when the door is mostly closed.

This is not what the manual says. The manual says open or closed no in between.

The car runs and shifts fine but the alarm will not lock doors or arm system when a door is almost closed.

I hope this helped.

 

Im usually pretty delicate with closing my doors, but I think I'm going to give my passenger door a good shove and see if it arms with one beep.

 

Any luck??

 

confused...are you talking about the factory immobilizer? Mine has never made a sound...is it supposed to?

 

Well when you push the fob yes. When you push it to lock the doors and arm the alarm it should chirp at you. Then when you push it to unlock/ disarm it should chirp again. I think it's two chirps when you arm it and one when you disarm. I can't remember for sure I never lock my car. If you try to arm it and it chirps then pauses and the chirps four times there is a fault. Your siren / chirping speaker might be dead if you've never heard it.

 

I have never heard a peep lol

 

Randy is you red light by vents on solid?

 

Does it flash the park lights at you? If it does then it's working just your siren is bad.
