The Master Warning Light came on. I have not synced my tpms sensors yet so that light is also on. I had auto zone pull the code and it read C1268 Transfer L4 Switch Circuit. There are no other symptoms. I stopped and shifted the new, 4low/center diff lock when close to home. it all shifted as expected. The other auto parts store did not pull a code when they tried and neither did torque pro through a bluetooth adapter.
