DESCRIPTION
HINT:
- The shift control system is a linkless type that does not use a shift cable.
- The shift and select sensors are a non-contact type.
- The 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 selector lever contains a shift sensor and a select sensor to detect the selector lever position (R, N, D or B). Because both sensors are controlled electrically by Hall elements, they can accurately detect shift positions in a reliable manner. Both sensors contain two systems of detection circuits, main and sub.
- The shift sensor outputs voltage, which varies between 0 and 5 V in accordance with the vertical movement of the selector lever, to the HV control ECU. The HV control ECU interprets low level voltage input from the shift sensor as the D or B position, middle level voltage as the home or N position, and high level voltage as the R 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 HV control ECU. The HV 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 HV control ECU determines the position of the selector lever in accordance with the combination of the signals from the shift sensor and select sensor.
HINT: After confirming DTC P0705 (INF 571, 572, 573, or 574), confirm M and S SHIFT SENSOR voltages using the Techstream.
M and S SHIFT SENSOR
HINT: After confirming DTC P0705 (INF 575, 576, 577, or 578), confirm SM and SS SHIFT SENSOR voltages using the Techstream.
