Note: The alarm system has a self-diagnosis
function, which allows a Ford dealer to carry
out fault diagnosis, using suitable specialist
equipment. In the event of a problem with the
alarm system, it is advisable not to tamper
with the components until appropriate fault
diagnosis has been carried out.Location
