  1. what diagnostic tool to buy?? alarm.

    Range Rover Sport / L320
    Alarm keeps going off again. Happened a while ago and I read on here it's 99% chance it's the hood switch and I replaced the hood switch and worked for about 1.5 years (Thanks forum :dance:). After a year and half it kept going off again and I replaced the hoodswitch again but it didn't do...
  2. Strange alarm sound

    Range Rover Mark III / L322
    2008 RR SC. I was pulling out of the grocer store into fast moving heavy traffic this evening and kind of hammered on it and an odd alarm sound came from the dash. I quickly glanced at the warning screen below the gauges and nothing was displayed. It was an electronic up and down tweet that...
  3. Alarm system disable '96 P38 HSE 4.6

    Range Rover Mark II / P38
    Gents, Is there an easy way to permanently disable the alarm system while still keeping the key fob entry? This system seems to be a little over kill for us guys out in the country. Thanks

  6. 2011 RRS - ALARM MALFUNCTION

    Range Rover Sport / L320
    Recently, after locking the car with the Key Fob, the siren will sound after 45 minutes to an hour of sitting. There has never been any indication that someone was trying to get into the vehicle, thereby setting off the alarm. It's gotten frequent enough that I hesitate to lock the RRS for...
  7. BECM in Alarm State

    Range Rover Mark II / P38
    Although I often follow this forum, it is the first time that I dare to participate to explain what is happening to me in my RR P38 2.5 TD LHD. The car worked with a key without remote control, one of the emergency ones, since it had the immobilizer canceled with the Nanocom. I had one of the...
  8. Alarm went off when fuse no 15 was changed

    Range Rover Mark III / L322
    Fuse no 15 (central locking, diagnostics+) was changed and the alarm went off. Unable to stop it for a short time despite disconnection of the battery. Then suddenly several fault codes appeared (incl. the air-suspension and central locking). Subsequently, after the alarm was silenced, an...
  9. Alarm keeps going off when unlocking

    Range Rover Mark III / L322
    Hi all, I have a 2003 L322. For a while now the alarm has been going off when I unlock the doors. It goes off for about 25 seconds or so and then stops. The doors unlock fine and I can start the car immediately, but the alarm keeps sounding off. This used to be an intermittent problem but...
  10. alarm keeps going off + dead battery

    Range Rover Sport / L320
    Had the alarm problem two years ago and had the passenger side hood latch and rear passenger side latch replaced under warranty. About 6 months ago the alarm kept going off so I bought another hood switch but the alarm stopped going off so I got lazy and never put it in, but recently it's been...
  11. Tailgate Alarm Warning

    Range Rover Sport / L320
    I just got my first RR Sport and love it! However, I notice there is no alarm when I have the tailgate up and put the car in D or R. I've driven off a few times with it up!! Ridiculously unsafe. Anyway, any insight on how to activate this? Thanks!
  12. Alarm going off randomly, hood switch or something else?

    Range Rover Mark III / L322
    Another question about my 2007 Full Size Supercharged. When I lock my car and leave it, the alarm will randomly go off. Way more than it should. It seems like it is worse in the summertime but that could be just a coincidence. When I was driving the range rover daily and parking it at work...
  13. Random alarm going off L320

    Range Rover Sport / L320
    I have a 2010 RRS SC and I have been having random alarm sounding issues. Reading this forum, I assumed it to be the hood latch sensor. I bypassed it and removed the switch. I checked continuity on the switch after removal and it was fine, so I assumed bypassing wouldn’t work and it did not. The...
  14. 2010 RRS alarm going off typically 15-20 after it is activat

    Range Rover Sport / L320
    I have 2010 RRS supercharged. For the past 6 months the alarm goes off consistently 15-20 minutes after I lock the car for no apparent reason. Pretty annoying. Does anyone else have a solution to this?
  15. ALARM goes off on start and randomly through the day.

    Range Rover Mark III / L322
    Hi everyone, first of all I want to say thanks for taking the time to read my message. Really depreciate it and hope that some of the seasoned vets in here could shed some advice. I also want to note that I have combed through the forums to see if I can find a solution before posting but I...
  16. P38 reset BECM success out of alarm mode

    Range Rover Mark II / P38
    I recently had success bringing life back to my P38 and thought I would write about it so others may find my experience helpful. Recently I returned from a store unlocked the door with the key and found the engine would not start and the instrument panel said engine disabled. I have no key fob...
  17. 94/95 RRC: Alarm ECU

    Range Rover Classic
    Hi, I'm new here as an RRC owner, but have been around various Rover forums a while as a D90 owner. I've concluded that you can't really start a 95 RRC after removing the ECU -- I want to get mine back up running so my door locks can operate via the fob. I need to track down a replacement...
  18. Alarm - What sets it off

    Range Rover Sport / L320
    So this might seem like an odd question but things have changed since 2008 (my rr sport year) in the alarm world. My truck makes no chirping noise when armed, just the side markers; The alarm brain is located on the right glove box side of the truck and I've "slammed" my hand against the truck...
  19. Is alarm supposed to honk or chirp when arming?

    Range Rover Sport / L320
    Since we bought this used my wife was wondering if arming/locking the car has an audible indicator. Thanks.
  20. Alarm goes some mornings

    Range Rover Sport / L320
    My 2008 Range Rover Sport SC alarm goes off onsome mornings. When I go to the vehicle it states that the right passenger door is open but that’s not the case. I looked at previous postings on this subject, and they allpoint to the hood latch which doesn't appear to be the case here...
