The horn on my Montero (2003) came on in the middle of the night, I could not disable it hence ended up disconnecting the battery.
Subsequently, the next morning I connected the battery but the issue continued. I then disconnected the horn cable. The horn is disconnected but I feel that the battery is draining.
Any suggestions? Is this a Alarm System malfunction? Can I disable the Alarm System? Please advise.
Thanks, Kamal
