    Yes  GO to  O4
    No  UPDATE the Inverter System Controller (ISC) to the latest calibration level.

  5. O4 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 DTCs.

    • 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  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.
