1999 S80 Keyless Entry/Alarm System

Discussion in 'Volvo S80' started by Deacon Eisenhart, May 3, 2005.

  1. I have noticed that sometimes my turn signals will flash when I lock the
    doors with the keyless remote, most of the time they do not flash. Why is
    that? The doors lock/unlock and the red light is flashing every two seconds
    on the dashboard.

    I wonder if Bill Gates is involved with my car?

    Those times when the turn signals don't flash, are the doors already
    locked beforehand? If so, yes, that's how the S80s are programmed.
    Repeatedly pressing on the "Lock" key of your fob will flash the
    lights only once.

  3. No, I can exit the vehicle with driver or all doors unlocked, close the
    door, and press lock and no lights.

    The only reason I knew they flashed was the other night before I
    disconnected the battery, they flashed when I locked the door. I
    disconnected the battery and charged it, and the next morning placed the
    battery back in. The lights still were flashing at that time when I locked
    the door.

    A day later, they are not flashing anymore.

    The interior lights DO come on when I unlock with remote.

    If one of the doors/trunk/hood is not closed properly, then the alarm
    doesn't set (lights don't flash) until that door/trunk/hood is closed.
    And if the microswitch in one door lock is defective (very common), then
    the alarm doesn't arm.

  5. Hmmm.

    Would those micro switches also be the same switches that indicated when the
    door is open or closed? They are all normal and work properly if (the
    display screen on the dash will tell me each door is open/closed).

    As far as I know the system is arming (i will trigger it today with an open
    window and lift the doorlock and check). I am getting the red flashing
    light on the dash every two seconds, which from the owners manual says means
    that the alarm is set.

    I haven't had to work on that part of the alarm yet, but I believe the
    same switch in the door lock is also used for the dome light. The only
    one I've worked on had a bad hood switch - try setting the alarm with
    the hood open and see what happens.

  7. The problem was solved. I was reading in one of the later posts.
    One of the hood latches must not have fully engaged.

    I open the hood and closed it a bit harder. Lights are flashing now.

    I don't like to slam the hood, but that did the trick.

  8. If you prefer to close the hood gently, can't you just then
    push down with the palm of your hand over each latch?

  9. It did not seem to work when I did that. For the most part, I just wondered
    why they weren';t flashing one day and now they were. I could really care
    less if latch switches catch or not. It will take somebody a while to steal
    the engine.

  10. Deacon...I am having a time learning the 00 keyless system
    "protocals"... as well...
    when driving the car home, this occured twice....i stopped to get
    gas...removed the
    keys, walked to the gas door and found it was locked...i removed the
    fob from my
    pocket and electronicaly unlocked the car...gased up, replaced the cap
    and closed the
    gas door...walked to drivers door and found the whole car locked...i
    unlocked the car and "let myself in"...it seemed the system was re
    locking itself every
    time a door opened or closed......i need to dig into the manual and see
    whats up...or
    how i should set the car not to do that...

  11. Hehe.

    Davids suggestion about pressing on the hood...that worked. I didn't think
    about it, but there are two latches, I just need to press lightly in the
    correct spot... Now I don't have to slam.
