My '10 LC will throw this light fairly regularly and it causes the cruise control to not work. It happens about 20% of the time when I start it up. The check engine light does NOT come on and the rig drives fine. What is causing this and how to fix? Thanks..

Probably your center differential lock aka CDL indicator flashing. Exercising it consistently might help.. but if not you’re looking at a bit more work.
More info:
Transfer case actuator issues are not uncommon on the 200-series. Not much documented solutions other than exercising the mechanisms regularly. Here's my attempt to provide more information on where and what the actuator is, how to service the transfer case actuator motor, and potentially provide some fixes.
Two main parts siamesed together that compose the transfer case actuator which is a plastic housing hanging off the rear:
1) Upper motor and rod is the center diff lock actuator/gearset
2) Lower motor and rod is the Hi/Lo actuator/gearset
Access is pretty easy and...

Many things can cause the blinking “Lo” light. Usually the check engine light comes on too. Evap system codes is a common cause this as an example. You generally have to clear codes for it to go away (for a while). Use a code reader to see what codes it’s throwing. If you don’t have a reader to any auto parts store and they will do it for you.
