DESCRIPTION
HINT
- The electronic shift lever system is a linkless type that does not use a shift cable.
- The shift and select sensors are non-contact type sensors.
- The transmission instrument panel shift assembly (shift lever) is a momentary type, which returns to its home position by spring reaction as the driver's hand is released from the shift lever after shifting.
The transmission instrument panel shift assembly (shift lever) contains a shift sensor and a select sensor to detect the shift lever position (home, R, N, D or B). Because both sensors operate using Hall elements, they can accurately detect the shift lever position in a reliable manner. Both sensors contain two detection circuits, a main and a sub circuit.
- The shift sensor outputs voltage, which varies between 0 and 5 V in accordance with the vertical movement of the shift lever, to the hybrid vehicle ECU. The hybrid vehicle control ECU interprets low level voltage input from the shift sensor as the R position, middle level voltage as the home or N position, and high level voltage as the D or B position.
- The select sensor outputs voltage, which varies between 0 and 5 V in accordance with the horizontal movement of the shift lever, to the hybrid vehicle control ECU. The hybrid vehicle control ECU interprets low level voltage input from the select sensor as the home or B position, and high level voltage as the R, N, or D position.
The hybrid vehicle control ECU determines the position of the shift lever in accordance with the combination of the signals from the shift sensor and select sensor.
