ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2300

DTC Code DTC Name
C2300 Actuator System Malfunction

DESCRIPTION

The shift control actuator assembly consists of the parking lock motor and the rotation angle sensor. The transmission control ECU assembly receives a P position switch signal from the EV control ECU and activates the parking lock motor by controlling current, causing the parking lock mechanism to switch. The transmission control ECU assembly also detects the rotor rotation angle through the rotation angle sensor to control timing of current application to the coils. The transmission control ECU assembly stores this DTC when it detects a malfunction in the shift control actuator system.

    6. Make sure the brake pedal is not depressed and turn the power switch on (ACC).

      Note

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

    7. A0026SE

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

      Note


      • 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.

        Tech Tips

        If the shaft is rotated quickly, the voltage value may not become a pulse waveform, so rotate the shaft at a speed of 1 rotation every 6 seconds.
