HYBRID CONTROL SYSTEM DIAGNOSIS SYSTEM


  1. DESCRIPTION


    1. The hybrid vehicle control ECU has a self-diagnosis system. If the computer, hybrid control system, or a component is not working properly, the ECU records the conditions that relate to the fault. The ECU also illuminates the master warning light in the combination meter assembly and provides other appropriate messages on the multi-information display, such as the HV system warning message, HV battery warning message, or discharge warning message.

      *1 MIL *2 READY Light
      *3 Master Warning Light *4 Charge Warning
      *5 Multi-information Display - -

      Tech Tips

      The master warning light will illuminate when the hybrid control system is malfunctioning and the light will blink when in inspection mode.

  2. 2 TRIP DETECTION LOGIC


    • When a malfunction is first detected, the malfunction is temporarily stored in the hybrid vehicle control ECU memory (1st trip). If the same malfunction is detected during the next drive cycle, the MIL is illuminated (2nd trip).

  3. FREEZE FRAME DATA


    • The hybrid vehicle control ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, as well as other data recorded at the time of a malfunction.

  4. AUXILIARY BATTERY VOLTAGE


    • If voltage is below 11 V, replace or recharge the auxiliary battery.

      Note

      After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

  5. MIL (Malfunction Indicator Lamp)


    1. The MIL is illuminated when the power switch is first turned on (IG), before the READY light comes on.

    2. When the READY indicator turns on, the MIL should turn off. If the MIL remains illuminated, the diagnosis system has detected a malfunction or abnormality in the system.

      Tech Tips

      If the MIL is not illuminated when the power switch is first turned on (IG), check the MIL circuit.

    • Open or short circuit in the rear motor (MGR), connectors or cables

  • DTC PRIORITY LEVEL AND TROUBLE AREAS


    • Each DTC diagnostic procedure for the hybrid control system consists of a combination of the various relevant system (circuit) inspections.

    • When multiple DTCs are output, performing each diagnostic procedure in order of priority can lead to a more accurate diagnosis.

    Tech Tips

    The "Example of Multiple DTCs being Output" below is only one example of a malfunction condition. Therefore, a determination should not be made based on this alone.


      Example of Multiple DTCs being Output:

    1. The power supply of the microcomputer decreases while the vehicle is being driven.


      1. DTCs are detected and the vehicle behavior is as follows.


      • Detected DTCs

      • P06B0-163 (Sensor Power Supply "A" Circuit / Open): Microcomputer malfunction*

      • P0A40-500 (Drive Motor "A" Position Sensor Circuit Range / Performance): Sensor and actuator circuit malfunction*

      • P0A40-506 (Drive Motor "A" Position Sensor Circuit Range / Performance): System malfunction*


        • *: Check the priority level in the "DTC Order of Priority" chart above.


      • Vehicle Behavior

      • System stopped

    2. The inspection order of priority is: Microcomputer circuit → power source circuit → communication circuit → sensor and actuator circuit → system circuit. Therefore, check the repair procedure for P06B0-163.

    3. Follow the repair procedures and replace the inverter assembly. Finish the repair.

    It is possible to check only the specified malfunctioning parts without having to check irrelevant parts.
