    Possible Sources 

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

  2. L1 PERFORM THE INVERTER SYSTEM CONTROLLER (ISC) SELF-TEST

    NOTE: P0A1A:06 generally sets as a result of other DTCs which should be diagnosed first. P0A1A:06 rarely sets alone.

    • Ignition ON.

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

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

    Yes  DIAGNOSE all other Inverter System Controller (ISC) DTCs, REFER to Diagnostic Trouble Code (DTC) Chart .
    No  For DTC only GO to  L2

    • 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  L3
    No  UPDATE the Inverter System Controller (ISC) to the latest calibration level.

  4. L3 CLEAR AND CHECK THE INVERTER SYSTEM CONTROLLER (ISC) DTCS

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

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

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

    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 Inverter System Controller (ISC). REFER to: Inverter System Controller [SOBDMC] .
    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.
