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

WARNING: This page is about a different variant/trim than selected.
  1. Refer to All Wheel Drive (AWD) for schematic and connector information.

    Normal Operation and Fault Conditions 

    The AWD module runs diagnostic checks on itself. If it detects a fault with internal hardware, programming or performance, it will set a DTC. Some internal faults may be caused by a module power or ground issue.

    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.

    • Enter the following diagnostic mode: CMDTC self-test for all modules.

    Are any voltage DTC set in other modules? 

    Yes  REFER to: Charging System - 1.5L EcoBoost (132kW/180PS) - I3 (Y1) . REFER to: Charging System - 2.0L EcoBoost (177kW/240PS) - MI4 .
    No  GO to  E3

  3. E2 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE GROUND

    • Ignition OFF.

    • Verify AWD module retaining nuts are secure. 89 lb.in (10 Nm)

    Were any of the fasteners loose? 

    Yes  TIGHTEN the AWD module retaining 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 AWD module 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
      PWR C3841-1

      		 Ground

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

    Yes  For Hybrid vehicles, GO to  E4For all others, GO to  E5
    No  REPAIR the open circuit.

  5. E4 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE GROUND - HYBRID ONLY

    • Disconnect the AWD module C3841 .

    • Ignition OFF.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C3841-46
      GFD650816Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance less than 3 ohms? 

    Yes  GO to  E5
    No  REPAIR the open circuit.

  6. E5 VERIFY THE CONCERN IS PRESENT

    • Connect AWD module C3841 .

    • Ignition ON.

    • Enter the following diagnostic mode: Clear and Retest CMDTC self-test.

    • Ignition OFF.

    • Open and close driver's door to initiate module shutdown.

    • Wait 1 minute for the AWD module to sleep.

    • Start engine, allow to idle for 1 minute.

    • Enter the following diagnostic mode: AWD On Demand and CMDTC self-test.

    Did the voltage or internal fault DTC set again? 

    Yes  INSTALL a new AWD module. REFER to: All-Wheel Drive (AWD) Module - 1.5L EcoBoost (132kW/180PS) - I3 (Y1)/2.0L EcoBoost (177kW/240PS) - MI4 . REFER to: All-Wheel Drive (AWD) Module - 2.5L Duratec - Hybrid (121kW/164PS) (BG) .
    No  The system is now operating correctly. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
