I had this happen years ago when I was driving on the beach (sand, of course) except the CHECK TOD light was not on and it was not manually engaged in 4L. My ride back to my camp site was "harsh". Turns sucked, as you seem to be relating to as well. Before I got back to my site, I stopped at a do-it-yourself pressure wash and gave it a good blast-down to get some of the sand and salt off of it. I shot the undercarriage very thoroughly. The salty air and being so close to the water left sea salt crystals all over the my VX, which we all know, cars LOVE. When I started it up and left, all was good. Maybe salty air built up on something and the ECM didn't like it and something was triggered, dunno. Still a mystery to this day.
And definitely triple check tire pressure. I know in my case, I had to let loose some pressure to drive on the beach but refilled back up at the ranger station pumps on my way out. Even if you didn't let any out, still a good measure.
Also, I would reinspect everything you did during your lift. If this happened so close to install, I would mark that as primary suspect for now.
Keep us updated.
