Partial arming
If an aperture (door, bonnet or tailgate) is not fully closed when the remote control lock
button is pressed, the horn will sound briefly to signal that an aperture is still open. The alarm will remain disarmed, but all of the closed apertures will lock.
As soon as the open aperture is fully closed, the system will automatically arm, signalled by three flashes of the hazard warning lamps, with interior space protection activating 30 seconds later.
Note: The vehicle will not superlock if an aperture (other than the bonnet) is open.

One goes off whenever it wants to, one goes off every morning at 07.00 and the other one goes off every time I race Toerags.

"This bulletin supersedes TSB LA419-004/2006 dated 27 January, which should either be destroyed or clearly marked to show it is no longer valid (e.g. with a line across the page).

Subject/Concern: Discovery 3/LR3 - Battery Back-up Sounder

Models:
Discovery 3 / LR3 Vin range: 5A000318-6A389525


Markets: Belgium and Netherlands

Section: 419-01

Summary:
A customer may report a concern that the vehicle alarm sounds with no theft attempt.

This bulletin has been re-issued to include a closing VIN.

Cause: Some vehicles have been built with an incorrect battery back up sounder (BBUS), or the unit has not been installed, or the correct unit is installed but there is a control module software error. The central junction box (CJB) is not recognizing the signal 'heartbeat' from the BBUS that incorporates the alarm tilt sensor. When the vehicle is locked, the incorrect or missing signal from the BBUS is seen as a theft attempt by the CJB and triggers the alarm.
Action: Should a customer express concern regarding the above, refer to the Service Procedure detailed in this bulletin."
