Code C2300 Lexus 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 the timing of current applied to the coils. The Transmission Control ECU outputs this Diagnostic Trouble Code (DTC) when it detects a malfunction in the shift control actuator system.
