Pinpoint Test AJ: AWD Module Power, Ground, Or Internal Fault

WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to ALL WHEEL DRIVE (AWD) 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 P0562:00 System Voltage Low: No Sub Type Information The AWD module detected battery voltage below 9 volts on the voltage supply input circuit.
    AWD P0563:00 System Voltage High: No Sub Type Information The AWD module detected battery voltage above 16 volts on the voltage supply input circuit.
    AWD P0603:00 Internal Control Module Keep Alive Memory (KAM) 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 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 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 P1397:00 System Voltage Out Of Self Test Range: No Sub Type Information CLEAR the DTC. Turn the ignition off. Wait 1 minute. Ignition ON. RETRIEVE Continuous memory DTCs from all modules.

    Possible Sources 

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

  2. AJ1 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 - 2.0L EcoBoost (177kW/240PS) - MI4 .
    No  GO to  AJ2

  3. AJ2 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  AJ3

  4. AJ3 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE POWER FOR VOLTAGE

    • Ignition OFF.

    • Disconnect the AWD module connector C3841 .

    • Ignition ON.

    • While manipulating the harness (wiggle test) measure:
      Positive Lead Measurement / Action Negative Lead
      C3841-1
      GFD691676Courtesy of FORD MOTOR COMPANY
      		 Ground

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

    Yes  GO to  AJ4
    No  REPAIR the circuit.

  5. AJ4 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.
