Pinpoint Test P: P0A1A:06

WARNING: This page is about a different car, the 2021 Ford F-150. 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 - Component Location .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    SOBDMC P0A1A:06 Generator Control Module: Algorithm Based Failures This DTC sets when the generator torque exceeds the calibrated threshold.

    Possible Sources 

    • Inverter System Controller (ISC) calibration
    • Inverter System Controller (ISC)

  2. P1 PERFORM THE BECM (BATTERY ENERGY CONTROL MODULE) SELF-TEST

    • Ignition ON.

    • Using a diagnostic scan tool, perform the BECM self-test and record any DTCs.

    Are there any BECM DTC's present? 

    Yes  DIAGNOSE all BECM DTC's. REFER to: High Voltage Battery, Mounting and Cables .
    No  GO to  P2

  3. P2 PERFORM THE INVERTER SYSTEM CONTROLLER (ISC) SELF-TEST

    • Ignition ON.

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

    Are there any Inverter System Controller (ISC) DTCs other than P0A1A:06 present? 

    Yes  DIAGNOSE all other Inverter System Controller (ISC) DTCs, REFER to the Diagnostic Trouble Code (DTC) Chart .
    No  For DTC P0A1A:06 only GO to  P3

  4. P3 VERIFY THE INVERTER SYSTEM CONTROLLER (ISC) CALIBRATION LEVEL

    • Verify the Inverter System Controller (ISC) is at the latest calibration level.

    Is the Inverter System Controller (ISC) at the latest calibration level? 

    Yes  GO to  P4
    No  UPDATE the Inverter System Controller (ISC) to the latest calibration level.

  5. P4 CLEAR AND CHECK THE INVERTER SYSTEM CONTROLLER (ISC) AND BECM (BATTERY ENERGY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, clear the Inverter System Controller (ISC) and BECM DTC's.

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

    Is DTC P0A1A:06 the only DTC present in the Inverter System Controller (ISC) and BECM? 

    Yes  GO to  P5
    No  The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  6. P5 TEST DRIVE THE VEHICLE

    • Access the SOBDMC and monitor the GTQ_CMD (Nm) PIDand

      Access the SOBDMC and monitor the GTQ_OUT (Nm) PID

    • While monitoring the PIDs, road test the vehicle under load (above 4000 RPM) REFER to: Road Testing Vehicle .

    Are the generator torque command and generator torque out PID readings separated by greater than 18 lb.ft (25 Nm) ONLY above 4000 RPM? 

    Yes  INSTALL a new hybrid drive unit. REFER to: Hybrid Drive Unit . CLEAR the Inverter System Controller (ISC) DTCs. REPEAT the self-test.
    No  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 Inverter System Controller (ISC). REFER to: Inverter System Controller [SOBDMC] .
