2010 Toyota Tundra Crewmax Platinum/Few Dash Lights Popped Up

Good morning, I'm new to this forum so it will be nice to talk with some folks a lot smarter than me when it comes to keeping my Toyota on the road. My truck is a 2010 and its been a workhorse all these years, but a gremlin is popping up from time to time as expected with a vehicle running 262,000 miles on it. Yesterday I cranked the truck up and the check engine light came on with the LSD Light staying amber and the 4LO light flashing. Thinking it was a sensor in the transfer case I checked to make sure it went into 4 high, which it did, and I don't use it a lot, so coming out of the setting was a little hesitant. I haven't checked 4 low in fear it will get stuck there but I will. Ran the AutoZone scan and it came back saying I needed a new ignition coil, which I will replace this weekend after I pick up the part, it has been running a little rough. Would the truck throw these lights that seem to point to the drivetrain if the ignition coil is going bad? I added a pic of the craziness for reference...thank you all!

Welcome to the forum and 'limp mode'....

Certain engine, transmission and support system errors/failures will throw their own code up to let you know what's wrong (the original source), but in some cases a 'sympathetic' code will be triggered (such as c1201) or others that will push the vehicle into 'limp' mode (which is the christmas tree of dash lights you are experiencing). Normally, you'll get a different feel in the throttle, truck won't shift beyond 4th gear, etc.. This helps minimize further damage to the truck's various systems and is designed to get you off the road and to a dealer/repair shop before something catastrophic occurs (permanent damage, collision, etc.).
