- Cannot verify shift completion
- Service 4WD message
- Shift hunts back and forth
Common Causes
- Encoder ring sensor failure
- Encoder contaminated with metal particles
- Wiring damage
- Shift motor assembly failure
Diagnostic Steps
- Read encoder position with scan tool
- Command shift and watch encoder response
- Inspect encoder wiring
- Check transfer case fluid for metal contamination
- Test encoder sensor output
Repair Notes
Replace encoder motor assembly. Flush transfer case if fluid is contaminated.
