Thanks, I did see the previous post with picture.
This note under U1D is confusing then:
”2 - Includes trailer tire pressure monitoring alert ONLY when (PTT) trailer tire pressure monitor system is factory ordered”
I was curious to hear from someone that didn’t have the PTT on their factory build order sheet and if they were receiving alerts. It appears the sensor setup is there with U1D but is there something missing if you don’t order PTT? Hope I am making sense. I understand you need U1D and the sensors but the notes make it seem that you have to order both from factory to get the alerts.
