ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2301

DTC Code DTC Name
C2301 Shift Changing Time Malfunction

DESCRIPTION

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

DTC No. DTC Detection Condition Trouble Area
C2301 A shift control actuator assembly (parking lock motor) internal malfunction (parking lock motor spins freely) is detected for 2 seconds or more.

  • Auxiliary battery

  • Shift control actuator assembly

  • Hybrid vehicle transaxle assembly

  • Transmission control ECU assembly

INSPECTION PROCEDURE

Note

It is not possible to clear the following DTCs using the intelligent tester: DTCs 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). After the repair, it is necessary to disconnect the P CON MAIN fuse and wait for at least 60 seconds to clear the DTCs.

PROCEDURE


  1. CHECK FREEZE FRAME DATA


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Chassis / Transmission Control / Trouble Codes.

    4. Read the freeze frame data of C2301.

      Result
      Result Proceed to
      IG (+B) voltage is 9 V or more A
      IG (+B) voltage is less than 9 V B

    5. Turn the power switch off.

  2. CLEAR DTC


    1. Turn the power switch on (IG).

    2. Enter the following menus: Chassis / Transmission Control / Trouble Codes.

    3. Read and record the DTCs and freeze frame data.

    4. Turn the power switch off.

    5. Disconnect the P CON MAIN fuse and wait for at least 60 seconds.

    6. Check for DTCs again to see if the DTCs are cleared.

  4. CHECK DTC OUTPUT (SIMULATION TEST)


    1. Connect the intelligent tester to the DLC3.

    2. Release the brake pedal and turn the power switch on (IG).

      Tech Tips

      Do not turn the power switch on (READY).

    3. Depress the brake pedal and move the selector lever to N.

    4. Enter the following menus: Chassis / Transmission Control / Trouble Codes.

    5. Check if DTCs are output.

      Result
      Result Proceed to
      C2301 is output A
      DTC is not output. B

    6. Turn the power switch off.

  5. CHECK SHIFT CONTROL ACTUATOR ASSEMBLY


    1. Disconnect the shift control actuator assembly connector.

    2. Remove the shift control actuator 3 bolts Click here.

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

    4. A01JD4N

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

      OK
      The shift control actuator assembly turns smoothly.

      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 cannot be disassembled.

  6. CHECK HYBRID VEHICLE TRANSAXLE ASSEMBLY


    1. A01JCH9E01
      Text in Illustration
      *1 Lock
      *2 Unlock
      *3 Rotate approximately 20°.

      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


      • Rotates the shaft using torque within 4 to 7 N*m (41 to 71 kgf*cm, 36 to 61 in.*lbf).

      • During this inspection, ensure 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.
