C2300

P311 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2300: Actuator System Malfunction
C2300 - Actuator System Malfunction

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 hybrid vehicle control ECU 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.
