C2301

P410 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2301: Shift Changing Time Malfunction
C2301 - Shift Changing Time Malfunction

DESCRIPTION

The transmission control ECU assembly receives a P position switch signal from the power management control ECU (HV CPU) 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.

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.
