U0114 - Lost Communication With Four-Wheel Drive Clutch Control Module

The Technical Definition: The primary computer network has lost its communication link with the 4WD/AWD control module.

Common Symptoms: The 4WD system becomes entirely inoperative, leaving the vehicle stuck in 2WD. You will likely see a "Service 4WD" message and a flashing or dead 4WD selector switch.

Typical Fix: Because the 4WD module is often mounted on the undercarriage, the most frequent fix involves repairing corroded or water-damaged wiring connectors. Replacing a blown fuse or fixing a loose ground wire resolves many of these issues before needing to replace the actual module.
