What does the immobilizer/alarm do, exactly?

[TWODAN]

the link says the clip is for years 97 to 2004. what do i use on a 2010?

As far as I am aware, the red clip will also work on the 987 but have no actual experience with a 987.2 model.

If you want to make sure that the clip will work, go out to your car and do this test to confirm:

Put the top down and windows up. Reach over the top of the windshield from the front and push up the plunger button inside where the top latch goes. While pushing up the button, turn on the alarm using the key fob and continue to depress the button for another 5 sec to make sure that the motion detector is activated. Now, release the top button and remove your hand from the interior carefully so as not to set off the motion detector. Even with the button released, the motion sensor should remain active (or the theives would just remove the clip to deactivate the motion sensor). Then, stick your hand in the car and wave it around. The alarm should go off (might take 3-5 secs).

Clip is fine on a 2011 so it should surely work for you. The alarm activation is painfully slow however at least for me.

So don't be disappointed when it takes 15 secs or more to go off!

Ok, so the alarm not honking i get.

What I don't get is why the alarm doesnt go off if i reach inside and open the door while the car is locked with the top down.

The car doesnt need a motion sensor to know that someone is opening the car from the inside.

Likewise, I would imagine that if someone used a J-hook when the roof is up to open the door, I doubt the alarm would go off until they tripped the motion sensor.

Can someone else confirm that the alarm does not trigger if you do a simulated break in with the top down?

ok so since noone will do my little test i will presume that opening the doors thru the roof should set off the alarm (but in my case it does not)

Well I checked my codes with the durametric and they say this:


Alarm
Current Fault Codes
________________________________________


33

Clearly I have some sort of issue going on. How to fix these ?
