ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2301

DTC Code DTC Name
C2301 Shift Changing Time Malfunction

DESCRIPTION

The transmission control ECU assembly receives a P position switch signal from the EV control ECU and then activates the shift control actuator assembly. At the same time, the transmission control ECU assembly detects the length of time it takes for the parking lock mechanism to switch. The transmission control ECU assembly stores this DTC when this length of time is longer than specified.

DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Memory

CAUTION / NOTICE / HINT

Note


  • Do not remove/install the auxiliary battery or disconnect the cable from the negative (-) auxiliary battery terminal before instructed.

  • It may not be possible to clear the following DTCs using the GTS: DTC C2300 (Actuator System Malfunction), C2301 (Shift Changing Time Malfunction), C2303 (Short in Power Source Relay Circuit), C2304 (Open or Short Circuit in U Phase), C2305 (Open or Short Circuit in V Phase), C2306 (Open or Short Circuit in W Phase), C2307 (Power Supply) and C2309 (Open in B+ Circuit). In such cases, disconnect the P CON-MAIN fuse and wait for at least 60 seconds to clear the DTCs after the repair.

  • 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.

    1. Apply that the parking brake.

    2. Disconnect the D8 shift control actuator assembly connector.

    3. Remove the 3 shift control actuator bolts.

      Click here

    4. Slightly pull the shift control actuator assembly away from the FCV transaxle with motor assembly.

    5. Reconnect the D8 shift control actuator assembly connector.

    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.

      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.
