Transfer Case Control Modules (TCCM)
The Transfer Case Control Module (TCCM) manages your 4WD or AWD system, controlling the transfer case motor and encoder. A failing TCCM can leave you stuck in 2WD or cause the “Service 4WD” message.
Common TCCM Issues
- Service 4WD warning light
- Unable to shift into 4WD
- Stuck in 4WD mode
- Grinding noise when shifting ranges
