The ECM uses these switches to detect the shift lever position.
The park/neutral position switch assembly sends the P, R, N and D position signals to the ECM. The ECM transmits signals to the combination meter assembly for the shift position indicator (P, R, N and D) in response to the signals received from the switch.
The transmission control switch is installed inside the lower shift lever assembly to inform the ECM of the shift lever position.
Switch terminal S is used to detect whether the shift lever is in D or S, and terminals SFTU and SFTD are used to detect the operation of the shift lever (if it is moved forward ["+" position] or backward ["-" position]) when S mode is selected. By transmitting signals to the ECM, the transmission control switch turns on both the shift indicator and S mode indicator when the shift lever is moved to S, and indicates the selected range through shift indicator.
The shift paddle switch (transmission shift switch assembly) is installed in the steering wheel. The ECM detects the operation of the shift paddle switch (transmission shift switch assembly) "+" (upshift) or "-" (downshift) when the shift lever is in D or S.*
