ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2300

DTC Code DTC Name
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 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 stores this DTC when it detects a malfunction in the shift control actuator system.

DTC No. DTC Detection Condition Trouble Area
C2300 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).

  • Transmission control ECU assembly

  • Auxiliary battery

  • Shift control actuator assembly

  • Hybrid vehicle transaxle assembly

  • Wire harness or connector
