Ford Galaxy alarm goes off for no reason

A common fault can be bonnet switch and also close the fresh air vents and see if it helps . Gusts of wind can cause a disturbance in the car which can be mistaken by a movement sensor. This is from another site re. this problem ,

Had experienced auto mechanic investigate-no success.


The Galaxy alarm system has a self test facility but its very lengthy and can be quite involved - depending on what is or is not found, along the way...

If your alarm is going off for no reason without double locking set:




If this is the case then the problem will normally be the bonnet switch as its exposed to the elements 24/7. There are two common faults with it - the biggest being the rubber boot that covers it has worn allowing moisture to enter the switch and cause false readings.The other is that the bonnet isn't closing tightly on the switch. This can be rectified by adjusting the bonnets rubber seating bung (one either side of the front cross member) until the bonnet sits tightly on the switch.




If your alarm is going off for no reason with double locking set:




This can be due to a couple of things. The biggest cause of false triggers is with the interior scanning system which activates automatically when you double lock the car. Ensure that when you set it every window is done up tightly, including the sunroof and boot as air moving in the interior will trigger the alarm! Other reasons will be damaged door/sunroof seals allowing drafts or connector problems.


You should be able to sort the problem with the the above -- If not, the very best advice is to have the vehicle connected to a diagnostic system / comouter to read and see whats going on. The alarm ecu ( control unit ) is then scanned to see what faults are occuring as they will be logged in the units memory and the fault is sorted then from there....
