Grand Voyager 2004 Alarm Issues
 

Hi,
Having an issue with my alarm, but only at night!
Will go off at random times, each night, never in the day.
The only way around it is to press the lock button 4 times.

What can i check?

Thanks!

Introduce the fob to the car again, get them antiquated, try a reconciliation!

- turn the key to the start POS but do not START the engine

- when the checks stop lock and unlock the doors FROM the FOB several times
- - - this will re-marry the KEYFOB and the PUTER

- lock in the usual way with the KEYFOB, does the alarm function normally ? - if not do the following :
__________________________________________________

- disconnect the batter for 5 minutes, your FOB and car are now divorced .. .. then reconnect the battery
- your battery and FOB are now acrimoniously divorced and won't speak to each other

- turn the key to the start POS but do not START the engine
- - - the PUTER will read all BUS's and door locks, do all checks, you will hear lots of clicks

- when the checks stop lock and unlock the doors FROM the FOB several times
- - - this will re-marry the KEYFOB and the PUTER

- start the car, while it warms up re-set the missing settings from the radio and the roof display
- stop the engine and lock in the usual way with the KEYFOB - does it work now ?

NOTE : an afterthought - when you think you have locked and alarmed etc the vehicle you / it hasn't finished. The vehicle polls the computer BUS for 15 minutes checking windows / doors / radio and lights left on etc. Only then is the alarm function fully functioning.

Thanks for that. So far so good.

- good , pleased to help !

I'm sorry for the diggin', but this seems to be similar to my problem..

In this case, it's a '08 Grand Voyager 2.8CRD Stow'N'Go. Almost every day the alarm triggers at night.. It is properly locked. Should I try what's stated on this topic?

Thank you in advance!
