P310 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P3147-240: Transmission Malfunction

DTC P3147-240 - Transmission Malfunction

DTC P3147-242 - Transmission Malfunction

DESCRIPTION

The HV transaxle assembly consists of the planetary gear unit, Motor, and Generator. The gear unit uses the planetary gear to split engine output in accordance with a driving request while the vehicle is driven or the HV battery is charged. The Motor assists engine output while increasing vehicle driving force. The Motor also converts the energy, which is consumed in the form of heat during normal braking, into electrical energy and recover it into the HV battery to effect regenerative braking. The Generator supplies power, which is used for charging the HV battery or driving the Motor. It also controls the stepless transmission function of the transaxle by regulating the amount of electricity generated to change Generator speed. In addition, the Generator is used as a starter Motor to start the engine. The transmission input damper absorbs the shock generated when the driving force from the engine is transmitted.
