Alarm going off - 2002 Land Rover Discovery Series II

  • bjmwh Nov 18, 2008

    When I lock the car with the remote the doors lock and the horn beeps twice and the flashers all come on and the car is locked. After some time the horn beeps twice, then nothing but say after 5 minutes it starts beeping more often and the alarm goes off. This does not happen all the time, I left the alarm in my drive way and it was more than 5 hours before it beeped again. Help!

Another option so you don;t have to remove the horn fuse all the time is to disconnect the motion sensors at the point where they join at the sensors.The sensors are only a backup your alarm will still be active and as the horn is the siren if this is disconnected say when your shopping then your alarm is virtually useless as only the hazards will go off.All the best Nev  retired alarm tech

Thanks, I took the Alarm fuse out of the the main box. I do not have the problem now and I think the problem was the movement sensor. My Disco is a 1997 and the sensor attached to the lining in side the car was coming away from the soundproofing due the age. I had not noticed this, so the slightest movement set the alarm off. I have glued the velcro back and after two attempts I no longer have the problem. I don't know if this is your problem as you have a newer Disco.

My 2001 TD5 discovery has the same problem and this started in the last 18 months.
Normaly the car is parked in a locked garage, and the car is not locked.
The alarm does not go off during the day when parked anywhere even when parked for long periods.

When we are away camping in the bush or caravan parks, if I think of it I remove the "horn fuse" under the bonnet at night and replace this in the morning, if I dont do this the alarm does not go off every night, but I rather do this, than me and everyone at the camp site being woken up at 0300 hr'
Maybe it is the night temperature, ??

I hope this is of some help. John L.L

CAR ALARM ISSUES


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.
