I have ordered subject alarm module to install on my 2011 Navigator. I got it directly from Lincoln accessories website to make sure I am going to get right model. Today I got it installed by local Lincoln dealer which btw took tech over 6 hours (!) to get it done. Thanks god I paid $95 up front for installation when ordering online, otherwise dealer might have charge me more.
When I came to pick up my car, I checked alarm operation and found impact sensors not working. Without being told where override switch and LED are located, I made complain after being told, tech left already so I have to come back next morning.
Same evening, I googled installation manual for this alarm and later found module location with LED and override switch hidden deep and taped to harness. After studying service manual, I was able to adjust both impact sensors: light and main after which alarm finally works as expected going off with single chirp with light hits at body or glass and turning siren on and off at serious impacts.
So it looks like in my case everything worked just fine, I only wish installer was more responsible and would not leave me on my own. To make it work I had to figure it myself and adjust completely uncalibrated module. It worked.
One thing I noticed is that the horn turns on in random periods unlike most alarms where signal has regular on and off intervals. This alarm does not. Anyone knows why is that?
