    Normal Operation and Fault Conditions 

    REFER to: Front Electric Drive Assembly - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    SOBDMB P060A:44 Internal Control Module Monitoring Processor Performance: Data Memory Failure This DTC sets with other DTCs due to external wiring issues, and sets alone when an internal error occurs.
    SOBDMB P060A:47 Internal Control Module Monitoring Processor Performance: Watchdog/Safety μC Failure This DTC sets with other DTCs due to external wiring issues, and sets alone when an internal error occurs.

    Possible Sources 

    • Secondary Inverter System Controller (S-ISC) calibration
    • Secondary Inverter System Controller (S-ISC)

  2. F1 CHECK FOR SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) DIAGNOSTIC TROUBLE CODES (DTCS)

    NOTE: P060A:44 and P060A:47 very commonly set with (and due to) many other S-ISC DTCs and it would be very rare to see these DTCs alone.

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

    Are any Secondary Inverter System Controller (S-ISC) DTCs other than P060A:44 or P060A:47 present? 

    Yes  DIAGNOSE all other Secondary Inverter System Controller (S-ISC) DTCs, REFER to Diagnostic Trouble Code (DTC) Chart .
    No  For DTC P060A:44 or P060A:47 only GO to  F2

  3. F2 VERIFY THE SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) CALIBRATION LEVEL

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

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

    Yes  GO to  F3
    No  UPDATE the Secondary Inverter System Controller (S-ISC) to the latest calibration level.

  4. F3 CLEAR AND CHECK THE SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    • Ignition OFF.

    • Wait 5 minutes.

    • Ignition ON.

    • Wait 5 minutes.

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

    Are DTCs P060A:44 or P060A:47 present in the Secondary Inverter System Controller (S-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 Secondary Inverter System Controller (S-ISC). REFER to: Inverter System Controller [SOBDMB] .
    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.
