the "triangle" could literally be anything, especially if the engine light is not on any more, including ABS problems to a bad wheel sensor due to an out of adjustment wheel bearing.

Is the check engine light (engine symbol) on as well?.

Proper software is the way to find issues with modern trucks.

For the engine it would be Insite software, and for the rest of the truck, Jpro software works well.
