DTC    C2300    Actuator System Malfunction

for Preparation Click here


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.

DTC No.
