DESCRIPTION
Tech Tips
-
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 lock control unit assembly (selector lever) is a momentary type, which returns to its home position by spring reaction as the driver's hand is released from the selector lever after shifting.
The shift lock control unit assembly (selector lever) contains a shift sensor and a select sensor to detect the selector lever position (Home, R, N, D or B). Because both sensors operate using Hall elements, they can accurately detect shift positions 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 selector 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 selector 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 selector lever in accordance with the combination of the signals from the shift sensor and select sensor.
