its the factory fit alarm siren is by the fluid res and you should have a red led above the hazard switch. The button where the interior light is is to disable the ultrasonic (that black circle next to the button is the ultrasonic)

if you deadlock the car the alarm will activate about 10-30 sec later and the led will flash every 5-10 sec or so

to see if the alarm works pop the bonnet so its on the catch then deadlock the doors wait 10-30 sec it the light start flashing open the bonnet and it should go off.

i have the same car but an 2000 model i also found the button (which is up by the interior light itself) and it does acitvate a red led on the hazard button!! And yes i have no clue what it is for either??

Anyone...:thumbs:

Right...

Ive been sorting the car out 2day and i disconnected the battery to sort the fogs out which i had no luck in doing..

Anyway i heard a faint noise coming from the drivers side near the Brake fluid.. Anyway i seen a small siren e.g alarm which i couldn't believe this i thought i never had one :tu: So there must be a loose connection somewhere i think and when i locked my car it made a faint beep noise...

Now moving on to the Immobisler were my interior light is on the corsa there is a small button with a small circle next to it(will get a pic soon) and then you hold you finger on the botton theres a small red light on the dash which flash for about 3-5 seconds then goes off..
I have no information on what model,make,serial number they are so i can't declare them... :td:

Does anybody now what i should do....
Its a 98 S reg 1.4i 16v corsa sport

Thanks Danny
