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 shift lever (transmission instrument panel shift assembly) 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 shift lever (transmission instrument panel shift assembly) contains a shift sensor and a select sensor to detect the shift lever position (Home, R, N, D or B). Because the shift sensor operates using Hall ICs and the select sensor operates using MR ICs, 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 power management control ECU (HV CPU). The power management control ECU (HV CPU) 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 power management control ECU (HV CPU). The power management control ECU (HV CPU) 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 power management control ECU (HV CPU) determines the position of the shift lever in accordance with the combination of the signals from the shift sensor and select sensor.
