Original wording in English

MODULE, Transfer Case Control (DTCM) If there are any ECU's being updated for Software updates this will cause an interuption in CAN communication which in combined with a shortened key cycle (CAN communication is still alive) can cause the C1472-92 DTCM Fault. If Vehicle sets C1472-92 verify the diagnostics by the following: (1.) Take Vehicle Scan to verify DTC is Active/Stored. Send to Tech Advisor to record DTC snapshot information. If Vehicle sets C1472-92 verify the repair by the following: (1.) Verify there are no Ground loose connections / concerns (G910A) by ensuring the ground stud securement is correct. (2.) Complete sleep cycle. Allow DTCM to fully shutdown. PRDNL lights will no longer illuminate. (3.) After complete shutdown, turn ignition on and shift out of Park. (4.) Shift back into part and complete shutdown of ignition cycle

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
