C2301

P410 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2301: Shift Changing Time Malfunction
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 outputs this DTC when this length of time is longer than specification.

INSPECTION PROCEDURE

NOTICE:
It is not possible to clear the following DTCs using the Techstream: 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

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Chassis / Transmission Control / Trouble Codes.

(d) Read the freeze frame data of C2301.

Result





(e) Turn the power switch off.

B -- REPLACE AUXILIARY BATTERY Components
A -- Continue to next step.

2. CLEAR DTC

(a) Turn the power switch on (IG).

(b) Enter the following menus: Chassis / Transmission Control / Trouble Codes.

(c) Read and record the DTCs and freeze frame data.

(d) Turn the power switch off.

(e) Disconnect the P CON MAIN fuse and wait for at least 60 seconds.

(f) Check for DTCs again to see if the DTCs are cleared.

NEXT -- Continue to next step.

3. CHARGE AUXILIARY BATTERY

(a) Charge the auxiliary battery.

NEXT -- Continue to next step.

4. CHECK DTC OUTPUT (SIMULATION TEST)

(a) Connect the Techstream to the DLC3.

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

HINT
Do not turn the power switch on (READY).

(c) Depress the brake pedal and move the selector lever to N.

(d) Enter the following menus: Chassis / Transmission Control / Trouble Codes.

(e) Check if DTCs are output.

Result





(f) Turn the power switch off.

B -- END (AUXILIARY BATTERY WAS INSUFFICIENTLY CHARGED)
A -- Continue to next step.

5. CHECK SHIFT CONTROL ACTUATOR ASSEMBLY

(a) Disconnect the shift control actuator assembly connector.

(b) Remove the shift control actuator 3 bolts Components.

(c) Slightly pull the shift control actuator assembly from the hybrid vehicle transaxle.

(d) 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.

NOTICE:
* 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.

NG -- REPLACE SHIFT CONTROL ACTUATOR ASSEMBLY Components
OK -- Continue to next step.

6. CHECK HYBRID VEHICLE TRANSAXLE ASSEMBLY

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





OK:

The shaft rotates smoothly in the lock and unlock directions.

NOTICE:
* 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.

(b) Set the shaft in the lock position after the inspection.

NG -- REPLACE HYBRID VEHICLE TRANSAXLE ASSEMBLY Components

OK -- REPLACE TRANSMISSION CONTROL ECU ASSEMBLY Components
