Intelligent Access and Auto Start-Stop Fails

[APCO_P25]

But now over the past couple months we’ve also noticed that the intelligent access feature (opening or locking door by placing hand on door handle sensors with key close by) only works on the driver door.

Hello
After the Sync3 System Update I had always the same Problem. I do each a Master Reset on the SYNC3 System and after this it works fine.

I heard if something plugged in at the trailer hitch disables it. I never meet anyone one who likes this feature. I hear vehicles are 'restarting' at stop signs

That will do it but it also disables your rear parking sensors.

I don’t mind the auto start stop.

Just a reminder on the access. Your hand going behind the handle is what unlocks it. Tapping the button on top of the handle locks it.

I had my 2018 Expedition serviced on Monday for smart locks not working on any doors and I had start / stop not working for few month. they diagnosed it as intrusion sensor failure and replaced the part (EB3Z-15K609-A) all door locks started to work normally and engine start / stop started to work as well. may be a coincidence.

have your dealer inspect intrusion sensor. I had mine replaced on monday for the same issue - only driver door's smart lock was working and start / stop was not working at all. they replaced intrusion sensor and everything is working now. Part replaced EB3Z-15K609-A

That’s interesting...I wonder what the connection is. Perhaps a faulty intrusion sensor is a battery drain? Because it’s absolutely a battery issue, so I’m just trying to think of the connection between the two.

Thanks!

X2 on that. Could this sensor be the drain we are looking for. If I charge by battery all the problems go away. I just don’t drive mine much right now.

Thanks,

Will forscan find this code? 12.4 is pretty low. Just over 50% of a new fully charged AGM.
