The transfer case shift control module is equipped with the ability to store diagnostic information which is useful to a technician in the event of a module, component or wiring failure. DTCs should not be cleared from the transfer case shift control module until these codes have been recorded or servicing the system has lead you to a repair and directed you to perform the "Clearing Flash Codes" operation. The following steps provide an easy way of clearing the flash codes properly.
Important: Replacing the fuse before the specified time may result in not clearing the DTCs.
