C2301

HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2301: Shift Changing Time Malfunction

DTC C2301 - Shift Changing Time Malfunction

DESCRIPTION

The transmission control ECU receives a P position switch signal from the hybrid vehicle control ECU and then activates the shift control actuator. At the same time, the transmission control ECU detects the length of time it takes for the parking lock mechanism to switch. The transmission control ECU outputs this DTC when this length of time is longer than specification.
