P2772
Four Wheel Drive (4WD) Low Switch Circuit Range/Performance
High severity
What it means
The 4WD-Low switch state is implausible against transfer case position feedback. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
