Hi,  I have a fault where horn sounds (short double beep) when I press lock on key fob, try locking with key on drivers door or locking from inside with the button on drivers door panel. All doors lock except right side door (drivers side). I took to a garage who ordered the complete lock assembly for that door (£400) and had exactly same problem so said I need to take it to a Ford garage.                 P.S. He also said the alignment of 3 prongs was OK and that he could probe signals which seemed to be working.                   Would appreciate some advice, specifically how BCM determines when there is a fault. In this case, the door ajar function is working and you can hear a clunk ( i.e. solenoid is trying to drive the lock catch).

Also, would Forscan be able to at least disable the horn beep function?

Thanks in advance.

I've got this issue on my 2018 custom, never happened before upto recently on intermittent occasions. Have applied copper ease to the locking mechanisms on all the doors but to no avail
