C2300

P410 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2300: Actuator System Malfunction
C2300 - Actuator System Malfunction

DESCRIPTION

The shift control actuator assembly consists of a parking lock motor and rotation angle sensor. The transmission control ECU assembly receives a P position switch signal from the power management control ECU (HV CPU) 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.

INSPECTION PROCEDURE

NOTICE:
- It may not be possible to clear the following DTCs using the Techstream: 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 Service Precautions.

PROCEDURE

B -- GO TO DTC CHART (ELECTRONIC SHIFT LEVER SYSTEM) C2304
A -- Continue to next step.

3. 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 C2300.

Result:





(e) Turn the power switch off.

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

4. 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.

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

(c) Depress the brake pedal and move the shift lever to select neutral (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.

7. CHECK TRANSMISSION CONTROL ECU ASSEMBLY (VC, RA, RB, E2)

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





Standard Voltage:

OK:

A waveform of 500 ms or less is generated.

HINT
- Perform this inspection with the connector connected.
- When changing from park (P) to neutral (N), or neutral (N) to park (P) with the power switch on (IG), a waveform will be generated for up to 0.5 seconds.
- The waveform shown is for reference only.

(e) Turn the power switch off.

Result:
