Alarm going off for no reason

Hi Everyone,

My alarm has been going off randomly for no apparent reason. After the horn stops blowing, my turn signal lights continue to flash, but with no sound from the horn.

Any ideas? Please help

Few things you need to double-check when enabling the alarm - see attached Alarm Guidance.

If this persist, disconnect the battery for a few minutes, reconnect, recalibrate the throttle position as per docs, set power windows limit as per docs, go for a long ride for the adaptation process, and try that alarm once again before putting everything in the bin!

Hope this helps a bit mate - fingers crossed.

Anthing aftermarket in the car??? Radio?? Alarm?? My 99 did the same thing and it turned out to be the micro switch on the side of the radio.
