I have not used 4x4 Low in a while. I activated it yesterday and got the message AdvanceTrac Off. However, when I switched back to 4x4 Hi, I got AdvanceTrac On. I checked for DTC codes and found none, and everything sounded normal.

I am not sure what is happening, as I don't remember that message ever coming on in the past, and the manual has the below note for when 4x4 Low is engaged. It makes me think it might be an issue.
NOTE: The AdvanceTrac system has the ability to take over control of the transfer case clutch and disable it during driving maneuvers when necessary.


Is it my memory that is failing me or is this an issue that I need take it in for before my 3/36 expires?

Thank you in advance for your assistance.

 

It's normal. Page 239 of the manual. In 4WD Low, all AdvanceTrac with RSC features are turned off.

 

Thank you Ricktwuhk.

Not sure why they did not include that info with the 4x4 system operation instructions on pages 220-224, they would have saved me a post.

 

Yup. That's what happens when switching into 4lo. Perfectly normal.
