NeilH Posted October 28, 2016 Report Posted October 28, 2016 I have a 2009 Galaxy III Gaia 2.2 tdci whose alarm keeps going off for no reason. Had to disconnect battery last night so looking for any suggestions urgently please. I lock doors with remote fob as normal and alarm goes off after a couple of minutes. I have double checked all doors closed. Tried to leave car unlocked so not arming the alarm but still goes off after couple of minutes. Just going to try reconnecting battery and connecting OBD reader and will update if I sort it, but would appreciate any suggestions where to look. Thanks, Neil. Quote
BrianH Posted October 28, 2016 Report Posted October 28, 2016 (edited) Don't know if the galaxy is the same, but most fords you could do a test on the alarm by operating any of the switches 10 times in quick succession - this would then make a blip sound everytime one was moved (for door sensors etc). You can then test the indivual switches (you may find one either doesn't blip at all, or blips a lot - if so its probably corroded inside, and wants either to be replaced or bypassed - if you bypass it then you should be able to prove if its the problem part before spending any money on bits. The bonnet switches they used used to fail regularly, particularly when it started getting cooler at night as they move around making and breaking the connection. I found this resulted in it arming the test mode so every time the car went over any sort of bump the hazard lights would flash - very annoying till you find out what the cause is. I found that disconnecting the bonnet switch on the mondeo was enough to stop the alarm coming on, but allowed it to be locked. Edited October 28, 2016 by BrianH Quote
