    Possible Sources 

    • Vehicle level voltage concern
    • AWD module voltage supply
    • AWD module ground
    • AWD module

  2. E1 CHECK FOR VOLTAGE DTC IN OTHER MODULES

    • Ignition ON.

    • Connect the diagnostic scan tool.

    • Retrieve continuous memory DTC.

    Are voltage DTC set in other modules? 

    Yes  REFER to: Charging System - Overview .
    No  GO to  E2
  3. E2 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE GROUND

    • Ignition OFF.

    • Verify AWD module retaining nuts are secure. Torque: 55 lb. in (6.2 Nm)

    Were any of the fasteners loose? 

    Yes  TIGHTEN the AWD module nuts to specification. RETEST the system for normal operation.
    No  GO to  E3
  4. E3 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE POWER FOR VOLTAGE

    • Ignition OFF.

    • Disconnect the AWD module connector C3841 .

    • Inspect harness connector for damage. Verify terminals are not splayed, damaged, or pushed out of the connector.

    • Ignition ON.

    • While manipulating the harness (wiggle test) measure:
      Positive Lead Measurement / Action Negative Lead
      C3841-1
      GFD658367Courtesy of FORD MOTOR COMPANY
      Ground

    Is the voltage greater than 10v and remain constant while wiggle testing the harness? 

    Yes  GO to  E4
    No  REPAIR the circuit.
  5. E4 VERIFY CONCERN IS PRESENT

    • Ignition ON.

    • Connect the diagnostic scan tool.

    • Clear continuous memory DTC.

    • Ignition OFF.

    • Open and Close Driver's door to initiate module shut down.

    • Wait 1 minute for AWD module to sleep.

    • Start Engine, allow to idle for 1 minute.

    • Retrieve continuous memory DTC.

    Did the voltage or internal fault DTC set again? 

    Yes  INSTALL a new AWD module. REFER to: All-Wheel Drive (AWD) Module  .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. Address the root cause of any connector or pin issues.
