Four Wheel Drive (4WD) Switch Circuit Range/Performance
The four-wheel-drive switch is sending inconsistent or out-of-range signals, making the vehicle unable to reliably shift between 2WD and 4WD modes. This can cause the system to malfunction or stay locked in one mode. The switch or its connections likely need service.
