C2307

HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2307: Power Source Malfunction

DTC C2307 - Power Source 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 outputs this DTC when it detects a malfunction in the parking lock motor system and/or the ground circuit.
