ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:P272C00

DTC Code DTC Name
P272C00 Park Pawl Motor Driving Time Too Long

DESCRIPTION

The hybrid vehicle control ECU receives a P position switch signal from the P position switch (transmission shift main switch) and operates the parking lock motor through current control to engage and release the parking lock.

If the hybrid vehicle control ECU detects a malfunction when operating the shift control actuator assembly, it stores this DTC.

    4. Slightly pull the shift control actuator assembly from the hybrid vehicle transaxle assembly.

    5. Reconnect the C2 shift control actuator assembly connector.

    6. Release the brake pedal and turn the power switch on (ACC).

      Note

      The shift control actuator assembly may operate if the power switch is turned on (IG) or (READY). Do not turn the power switch on (IG) or (READY) during this inspection to prevent the shift control actuator assembly from operating while in contact with the splines.

      Using a screwdriver with its tip wrapped with protective tape or a piece of cloth, rotate the shaft.

      Note


      • During this inspection, make sure to use a screwdriver with its tip wrapped with protective tape or a piece of cloth to prevent the splines of the actuator from being damaged.

      • The shift control actuator assembly cannot be disassembled.


      1. Confirm that the shaft of the shift control actuator assembly rotates smoothly.

        OK
        The shaft of the shift control actuator assembly rotates smoothly.

      2. Measure the voltage according to the value(s) in the table below.

        Note

        When measuring the voltage, turn the shift control actuator assembly slowly.

      Wrap the shaft with a piece of cloth and turn it using pliers.

      OK
      The shaft rotates smoothly in the lock and unlock directions.

      Note


      • Rotate the shaft using torque between 4.0 and 7.0 N*m (41 and 71 kgf*cm, 36 and 61 in.*lbf).

      • During this inspection, make sure to use a piece of cloth to prevent the shaft splines from being damaged.

    2. Set the shaft in the lock position after the inspection.
