Operation of Parking Lock

The operation signal from/to the P position is sent from the main SW or power SW to the transmission control ECU via the hybrid vehicle control ECU. At that time the transmission control ECU operates the P CON MTR relay, activates the parking lock actuator with an appropriate control of electric current, and lights up the main SW when the shift is in the P position. If the system has an abnormality in the parking lock operation, it informs the driver of the system abnormality by lighting up the master warning light on the combination meter, displaying a warning of the system abnormality on the multi-display, and blinking the indicator light of the main SW.
