From the service manual...
The TCCM features a cold temperature strategy which is used to warm up the front axle in cold temperatures to improve driveline synchronization. When ambient temperature is below 32 F (0 C). IWEs will engage after initial key cycle and a driven gear is selected. Hubs will stay engaged regardless of 4x4 mode change for proximately 2 miles (3km). Once distance traveled has been achieved IWEs will disengage if vehicle is in 2H. Distance traveled will reset only if the temperature is below calibrated threshold and another key cycle has occurred or customer shifted to park and back to a driven gear within the same key cycle.
