Question about Cars & Trucks
You can probably reset it by disconnecting the battery for a while, but you really need to find out what the code(s) are. Some codes set the MIL immediately on the first ignition cycle, others take 2 or 3 failures. You could also pull the fuses PCM BAT and PCM IGN...I would like to suggest, however, to get it looked at by a mechanic so he can tell you what they mean, some do it for free.

No. It's just a question of aerodynamics.
The current combination of vehicle plus the long trailer simply results in the vehicle being affected by the turbulent air created by a semi. All cars are affected to some extent, but as you're in a taller vehicle with a long trailer you're affected even more. Without wishing to criticise your vehicle choice, it's probably worse as it's a US design: although they're often very big and powerful, they do tend to handle like a boat compared to European and Asian models, but on the flipside you simply don't get many non-US models that are that are as big although many produce similar power output using smaller engines which are more modern and efficient.
All you can realistically do to minimise it is to ensure that your tyre pressures are correct and that there is no adverse wear to steering or suspension components. Also check that your towing hitch is at the right height and loading and that there's an effective tow-hitch stabiliser fitted which is appropriate for the size of the load. You'll also find that if you carry loads on the roof of your vehicle it will make matters far worse, so try to avoid doing so.
