430 F430 Alarm issue

Yes, there is a motion detector (anti-lift sensor), but no adjustment as far as I am aware. It may also be possible that one of your doors/frunk lid/engine lid switches is out of adjustment/faulty. Some wiring diagrams (Scud) show some kind of ultrasonic detectors, but I don't have any information on them.

The anti-lift sensor appears to be located in the very forward centre console under the dash. See DK35

I don't know if you can interrogate the Alarm ECU with an OBD2 scanner (???)

Thank you Ian, that's a BIG help!

For info, the alarm system appears to get data from both:
1) the door open microswitches near the door hinges (also responsible for putting the red door lights on)
2) the driver's (and possibly the passenger's) door latch mechanism (inside the door), also responsible for putting on the door open indication on the dash when the ignition is turned on. These also put on the interior light.

Are any of the doors/lids not properly closed?

Latch switches discussed here:

If your door or interior lights are on or your door open indication is present, with the doors closed, then perhaps the door switches are faulty.
Similarly, if you have any (frunk/engine) lid open indications when closed, these microswitches may be faulty.

 

Thank you for that additional information. I've turned off the interior light and have no door-ajar messages.

I think I'll try to locate the anti-lift sensor and disconnect it to see if that has any effect on the erroneous alarms.
