Pinpoint Test C: AWD (All-Wheel Drive) Module Power, Ground, Or Internal Fault

  1. Refer to FOUR WHEEL DRIVE SYSTEMS for schematic and connector information.

    Normal Operation and Fault Conditions 

    If the AWD module observes an overpower or a low voltage condition, a DTC is set.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition

    AWD P0605:00 Internal Control Module Read Only Memory (ROM) Error: No Sub Type Information The AWD module detected an internal fault which may have been caused by a voltage supply concern to the module.
    AWD P0607:00 Control Module Performance: No Sub Type Information The AWD module detected an internal fault which may have been caused by a voltage supply concern to the module.
    AWD P060A:00 Internal Control Module Monitoring Processor Performance: No Sub Type Information The AWD module detected an internal fault which may have been caused by a voltage supply concern to the module.
    AWD P060B:00 Internal Control Module A/D Processing Performance: No Sub Type Information The AWD module detected an internal fault which may have been caused by a voltage supply concern to the module.
    AWD P060C:00 Internal Control Module Main Processor Performance: No Sub Type Information The AWD module detected an internal fault which may have been caused by a voltage supply concern to the module.
    AWD P064F:00 Unauthorized Software/Calibration Detected: No Sub Type Information Sets when the AWD module detects unauthorized software/calibration detected.
    AWD P068A:00 ECM/PCM Power Relay De-Energized - Too Early: No Sub Type Information The AWD module detected 0 volts on the voltage supply input circuit before it was expected.
    AWD P166E:00 Internal Control Module All Wheel Drive Disconnect Control Performance: No Sub Type Information This DTC sets when a malfunction has been detected by the AWD module.
    AWD P1674:00 Control Module Software Corrupted: No Sub Type Information Sets when the AWD module detects control module software corrupted.

    Possible Sources 

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

  2. C1 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 - 2.3L EcoBoost (199kW/270PS) , or REFER to: Charging System - 2.7L EcoBoost (238kW/324PS) .
    No  GO to C2 

  3. C2 CHECK VOLTAGE AND GROUND TO THE AWD (ALL-WHEEL DRIVE) MODULE

    • Ignition OFF.

    • Disconnect AWD module C2371.

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2371 Pin 17

      		 C2371 Pin 46
      C2371 Pin 1
      GFD758227Courtesy of FORD MOTOR COMPANY
      		 C2371 Pin 46

    Is the voltage between 11 and 14 volts? 

    Yes  GO to C4 
    No  GO to C3 

  4. C3 CHECK VOLTAGE TO THE AWD (ALL-WHEEL DRIVE) MODULE

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2371 Pin 17
      GFD758227Courtesy of FORD MOTOR COMPANY
      		 Ground
      C2371 Pin 1
      GFD758227Courtesy of FORD MOTOR COMPANY
      		 Ground

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

    Yes  REPAIR the circuit. CLEAR all CMDTC.
    No  VERIFY BCMC fuse 25(15A) and fuse 54(40A)is OK. If OK, REPAIR the open circuit or short to power. If not OK, REFER to OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify possible causes of the circuit short. CLEAR all CMDTC.

  5. C4 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  CHECK OASIS for any applicable service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, 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.
