Pinpoint Test Aw: P0DFC

  1. NOTE: The Secondary Inverter System Controller (S-ISC) is referred to as the SOBDMB (Secondary On-Board Diagnostic Control Module B) in the scan tool.

    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 P0DFC:00 Generator Position Sensor Not Learned: No Sub Type Information This DTC sets if the SEDID block is programmed, but the data is determined to be out of range.

    Possible Sources 

    • SEDID block programming
    • Secondary Inverter System Controller (S-ISC) calibration

  2. AW1 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  AW2
    No  UPDATE the Secondary Inverter System Controller (S-ISC) to the latest calibration level.

  3. AW2 VERIFY THE SECONDARY INVERTER SYSTEM CONTROLLER (S-ISC) SEDID BLOCK HAS BEEN PROGRAMMED CORRECTLY

    NOTE: To avoid confusion the TRID information corresponds with the primary (rear) electric drive system and is stored in the primary ISC (SOBDM-C). The SEDID stores similar but different information which corresponds with the secondary (front) electric drive system and is stored in the S-ISC (SOBDM-B).

    • Verify the Secondary Inverter System Controller (S-ISC) SEDID block has been programmed correctly. Refer to Module Reprogramming on the scan tool.

    Has the SEDID block been successfully programmed? 

    Yes  GO to  AW3
    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, reflash the Secondary Inverter System Controller (S-ISC) SEDID block.

  4. AW3 REPEAT THE SELF-TEST

    • CLEAR the Secondary Inverter System Controller (S-ISC) DTCs.

    • CARRY out the Secondary Inverter System Controller (S-ISC) self-test.

    Is DTC P0DFC present? 

    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, reflash the Secondary Inverter System Controller (S-ISC) SEDID block. If the concern is still present after the SEDID block flash, it is necessary to seek additional help. REFER to the Service Repair And Technical Assistance Process.
    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, the SEDID block was not programmed correctly or was erased.
