Clearing Diagnostic Trouble Codes

- Perform the following to clear the diagnostic trouble codes (DTC) and stored memory from the transfer case control module (TCCM).

1. Turn the ignition switch to the "OFF" position.
2. Remove the 20-amp T-case fuse (Number 2).
3. Wait at least 40 seconds then replace the fuse.
4. Cycle the ignition switch from "RUN" to "OFF" five times to clear diagnostic trouble code 1 from the TCCM.

Important:
- The codes will not clear if the 20-amp T-case fuse is not removed for at least 30 seconds.
- Code 1 will continue to occur until the ignition switch is cycled from "RUN" to "OFF" five times.
