Pinpoint Test Bl: P0560, P0562

WARNING: This page is about a different car, the 2022 Ford Police Interceptor Utility and 2022 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Normal Operation and Fault Conditions 

    Refer to Electric Powertrain Control - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    SOBDMC P0560:00 System Voltage: No Sub Type Information This DTC sets when the internal processor voltages are greater than a calibrated range.
    SOBDMC P0562:00 System Voltage Low: No Sub Type Information This DTC sets when the internal processor voltages are less than a calibrated range.

    Possible Sources 

    • Wiring, terminals or connectors
    • Low 12V battery voltage

  2. BL1 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CIRCUIT FOR VOLTAGE

    • Ignition OFF.

    • Disconnect Inverter System Controller (ISC) C1458A .

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1458A-K3
      GFD659138Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage greater than 11.5 V? 

    Yes  GO to  BL2
    No  DIAGNOSE the low voltage symptom. Refer to Charging System . Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs.

  3. BL2 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CIRCUIT FOR VOLTAGE

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1458A-K3
      GFD659138Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage less than 16V? 

    Yes  GO to  BL3
    No  DIAGNOSE the high voltage symptom. Refer to Charging System . Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs.

  4. BL3 CHECK FOR INVERTER SYSTEM CONTROLLER (ISC) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, clear the Inverter System Controller (ISC) DTCs.

    • Allow the Inverter System Controller (ISC) to complete a normal power down sequence.

    • Using a diagnostic scan tool, perform the Inverter System Controller (ISC) self-test.

    Is DTC P0560 or P0562 present in the Inverter System Controller (ISC)? 

    Yes  GO to  BL4
    No  Test is complete, the system is operating correctly at this time.

  5. BL4 CHECK THE PSR VOLTAGE PARAMETER IDENTIFICATIONS (PIDS)

    • Access the SOBDMC and monitor the ECU_VPWR (V) PID

    • Access the SOBDMC and monitor the ECU_VPWR_HR (V) PID

    Are the PID voltages within 3 volts of each other? 

    Yes  While monitoring the PIDs, inspect the harness for an intermittent circuit issue while wiggling the harness at the Inverter System Controller (ISC).
    No  REPAIR the affected circuit.
