MOTOR GENERATOR CONTROL SYSTEM, Diagnostic DTC:P0E3116, P0E3117, P0E311F

DTC Code DTC Name
P0E3116 DC/DC Converter Voltage Sensor "A"(VL) Circuit Voltage Below Threshold
P0E3117 DC/DC Converter Voltage Sensor "A"(VL) Circuit Voltage Above Threshold
P0E311F DC/DC Converter Voltage Sensor "A"(VL) Circuit Intermittent

DESCRIPTION

The motor generator control ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The motor generator control ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.

  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for 2 minutes or more.

  5. Turn the power switch on (IG) and turn the GTS on.

  6. Turn the power switch on (READY) and wait for 5 seconds or more.

  7. Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.

  8. Check the DTC judgment result.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform driving pattern again.

PROCEDURE


  1. CHECK DTC OUTPUT


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control and Motor Generator / Trouble Codes.


      Powertrain > Hybrid Control > Trouble Codes
      Powertrain > Motor Generator > Trouble Codes

    4. Check for DTCs.

      Tech Tips

      P0E3116, P0E3117 or P0E311F may be stored due to a malfunction which also causes the DTCs in the preceding table to be stored. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.

    5. Turn the power switch off.
