DESCRIPTION
The shift control actuator consists of the parking lock motor and the rotation angle sensor. The transmission control ECU 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 also detects the rotor rotation angle through the rotation angle sensor to control timing of current application to the coils. The transmission control ECU outputs this DTC when it detects a malfunction in the shift control actuator system.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C2300 | Decrease in the power source voltage (+B), open or short in the P CON MTR relay (transaxle parking lock control relay) or shift control actuator assembly (parking lock motor or rotation angle sensor), or internal malfunction of the shift control actuator assembly (parking lock motor or rotation angle sensor). |

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.
