Perform the AWD CONTROL MODULE VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612764-S24771594392014043000000) .
5. INTERMITTENT WIRING AND CONNECTORS The conditions necessary to set this DTC are not present at this time. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit. Wiggle test the wiring harness and connectors while checking for shorted and open circuits. Using the scan tool, monitor the data related to this circuit while performing the wiggle test. Look for the data to change or for the DTC to reset. Were there any problems found? Yes Repair as necessary. Perform the AWD CONTROL MODULE VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612764-S24771594392014043000000) . No Test Complete.
