    2. Turn the ignition switch off.

    Result: 

    B 

    GO TO DTC CHART (ELECTRONICALLY CONTROLLED BRAKE SYSTEM). Refer to  DIAGNOSTIC TROUBLE CODE CHART [12/2019 - 10/2021]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2021 - 11/2023] 

    Result: 

    A 

    See step  3

  3. CHECK DTC OUTPUT (HYBRID CONTROL) 
    1. Check for DTCs.

      Powertrain > Hybrid Control > Trouble Codes 

      Result

      Result Proceed to
      P060A-94 only is output. A
      DTCs except P060A-94 are output. B
    2. Turn the ignition switch off.

    Result: 

    B 

    GO TO DTC CHART (HYBRID CONTROL SYSTEM). Refer to  DIAGNOSTIC TROUBLE CODE CHART [12/2019 - 09/2020]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [09/2020 - 10/2021]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2021 - 11/2023] 

    Result: 

    A 

    See step  4

  4. CHECK FREEZE FRAME DATA (HYBRID CONTROL) 
    1. Read the Freeze Frame Data of DTC P060A-94.

      Powertrain > Hybrid Control > Trouble Codes 

      Result

      Result Proceed to

      Vehicle was stopped ("FR Wheel Speed" and "FL Wheel Speed" are between 0 and 1.4 km/h (0 and 1 mph)) and "Vehicle Speed" was less than 3 km/h (2 mph) B
    2. Turn the ignition switch off.

    Result: 

    A 

    GO TO MOTOR RESOLVER CIRCUIT 

    For the inspection method of the motor resolver circuit, refer to DTC P0A3F-16.

    Refer to DTC P0A3F-16: Drive Motor "A" Position Sensor Circuit Voltage Below Threshold; DTC P0A3F-1F: Drive Motor "A" Position Sensor Circuit Intermittent [12/2019 - 11/2023]

    Result: 

    B
