It is a common 200 issue for the center diff lock light to flash when it is cold if it does not get used. You can drive a bit, turn the truck off and on and it goes away. The key is to use periodically in 4lo and lock center diff. Most LX owners never use either. I looked at one that the dealer unplugged the diff lock to prevent it from flashing. Not sure it what is listed is related but sounds likely.
My 2013 did it some and then the weeklong snowmaggedden with lots of center diff use cleared it up. I believe the center diff lock actuator is tested on start up and if gummed up, it causes an indicator light.
