Haptic Motor Menu

[Frank2015_1990]

Hello,

New here. I just got a used 2015 Yukon SLT and cannot get both the left and right seat haptic motors to come on at all. I did some checking and disconnected both the left and right motors and applied 12V to them and heard each of them go off just fine. However when i go into the intellilink menu, under vehicle settings, there is no option for me to change the alert type from beep to vibrate. Is this a software update of some kind? I can not find any information about this anywhere.

David,

Thanks. Yes I have seen this but I do not have any  “Service Driver Assist” message nor do i have a setting to change the alert type from beep to vibrate. Since this is a 2015 I’m wondering if there is some kind of IntelliLink update that will give me the option to switch the alert type from beep to vibrate.

Not sure if my issue has happened to anyone else....but i went to the dealer and they couldn't figure it out either. They hooked up their controller to the Trucks ECU and were able to actuate the seat haptic motors from there but, just like me, could not find a menu anywhere to turn them on. Finally when they connected the car and updated the software, the menu showed up! The dealer was shocked since he had never seen this kind of issue. Hope this helps anyone else who is having the same issue.
