wisemk Posted August 29, 2016 Share Posted August 29, 2016 Hi, my Elise s2 has just developed this problem. The horn gives a short blast every 5 mins or so. Has anyone any ideas as to what could be causing this? I have checked all of the Alarm switches and they seem to be functioning. The car runs ok but the horn still goes off whilst driving. The only way I can stop it is to disconnect the battery. Link to comment Share on other sites More sharing options...
wisemk Posted August 30, 2016 Author Share Posted August 30, 2016 On further investigation the horn is going off exactly every 1 min 28 secs. Removing the Horn relay obviously stops the horn. I assume that something pulses every 1 min 28 secs and is shorting to the horn relay. I have contacted the alarm people and they state that the alarm system is not wired to the horn of the car. Does anyone know what pulses every 1 min 28 secs? When I get time I shall be removing the fuse panel and relay panel to see if I can see the short.
