  1. CONFIRM MODEL 
    1. Choose the model to be inspected.

      Result

      Result Proceed to
      for Gasoline Model A
      for HV Model B

    Result: 

    See step  5

    Result: 

    See step  2

  2. CHECK FOR DTCs (Engine) 
    1. Check for DTCs.

      Powertrain > Engine > Trouble Codes 

      HINT: 

      If DTC U0300-51, U0300-57 or U0301-57 is output, inspect the SFI system first as a SFI system DTC may be stored.

      Result

      Result Proceed to
      SFI system DTC is not output A
      SFI system DTC is output B

    Result: 

    GO TO SFI SYSTEM 

    for G16E-GTS: Refer to HOW TO PROCEED WITH TROUBLESHOOTING [09/2022 - ]

    for M20A-FKS: Refer to HOW TO PROCEED WITH TROUBLESHOOTING [06/2018 - ]

    Result: 

    See step  3

  3. CHECK FOR DTCs (HEALTH CHECK) 
    1. Using the GTS, perform a health check.

      OK

      ECUs other than the forward recognition camera do not output specification information mismatch DTCs related to the ECM.

      Result

      Result Proceed to
      DTC is not output A
      DTC is output B

    Result: 

    REPLACE ECM 

    for M20A-FKS: Refer to REMOVAL [11/2022 - 03/2023] , or refer to REMOVAL [03/2023 - 09/2024] , or refer to REMOVAL [09/2024 - ]

    for G16E-GTS: Refer to REMOVAL [11/2022 - 09/2024] , or refer to REMOVAL [09/2024 - ]

    Result: 

    See step  4

  4. READ VALUE USING GTS (Powertrain Information) 
    1. Using the GTS, read the Data List.

      Chassis > Front Recognition Camera > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Powertrain Information Powertrain information Conventional, SS, HV, PHV, EV, 1MHV, FCV or Default Value Conventional: Conventional vehicle
      SS: w/ Stop and start vehicle
      HV: HEV
      PHV: PHEV
      EV: BEV
      1MHV: 1MHV
      FCV: FCEV
      Default Value: Vehicle information not confirmed
      -

      Chassis > Front Recognition Camera > Data List 

      Tester Display
      Powertrain Information

      HINT: 

      • When the specification stored by the forward recognition camera and the vehicle specification do not match, there is a malfunction in the specification information stored by the forward recognition camera. Therefore, replace the forward recognition camera.
      • When the specification stored by the forward recognition camera and the vehicle specification match, a ECM with different specifications may be installed. Therefore, replace the ECM.

      Result

      Result Proceed to
      • Vehicle information stored in the forward recognition camera and actual vehicle specifications do not match
      • Not confirmed is displayed
      A
      Vehicle specification information stored in forward recognition camera and actual vehicle specifications match B

    Result: 

    REPLACE FORWARD RECOGNITION CAMERA 

    Refer to REMOVAL [11/2022 - ]

    Result: 

    REPLACE ECM 

    for M20A-FKS: Refer to REMOVAL [11/2022 - 03/2023] , or refer to REMOVAL [03/2023 - 09/2024] , or refer to REMOVAL [09/2024 - ]

    for G16E-GTS: Refer to REMOVAL [11/2022 - 09/2024] , or refer to REMOVAL [09/2024 - ]

  5. CHECK FOR DTCs (Hybrid Control) 
    1. Check for DTCs.

      Powertrain > Hybrid Control > Trouble Codes 

      HINT: 

      If DTC U0300-51, U0300-57 or U0301-57 is output, inspect the hybrid control system first as a hybrid control system DTC may be stored.

      Result

      Result Proceed to
      Hybrid control system DTC is not output A
      Hybrid control system DTC is output B

    Result: 

    GO TO HYBRID CONTROL SYSTEM 

    Refer to DIAGNOSTIC TROUBLE CODE CHART [09/2022 - ]

    Result: 

    See step  6

  6. CHECK FOR DTCs (HEALTH CHECK) 
    1. Using the GTS, perform a health check.

      OK

      ECUs other than the forward recognition camera do not output specification information mismatch DTCs related to the hybrid vehicle control ECU.

      Result

      Result Proceed to
      DTC is not output A
      DTC is output B

    Result: 

    REPLACE HYBRID VEHICLE CONTROL ECU 

    Refer to REMOVAL [09/2022 - ]
