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/L CTSY fuse.
3. Wait at least 2 minutes and 30 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 DTC's will not clear if the 20-amp T/L CTSY fuse is not removed for at least 2 minutes and 30 seconds.
- DTC 1 will continue to occur until the ignition switch is cycled from "RUN" to "OFF" five times.
