P1815
P1815 M-MODE SWITCH
Description
- The manual mode switch [mode select switch and position select switch (shift-up/shift-down)] is installed in the A/T shift selector assembly.
- The mode select switch detects the position (the main shift gate side or manual shift gate side) of the selector lever and transmits a manual mode signal or a non-manual mode signal to the unified meter and A/C
amp. Then, the TCM receives a manual mode signal or non-manual mode signal from the unified meter and
A/C amp.
- The position select switch (shift-up) detects that the selector lever is shifted to the shift-up side of the manual shift gate and transmits a manual mode shift up signal to the unified meter and A/C amp. Then, the TCM
receives a manual mode shift up signal from the unified meter and A/C amp.
- The position select switch (shift-down) detects that the selector lever is shifted to the shift-down side of the manual shift gate and transmits a manual mode shift down signal to the unified meter and A/C amp. Then, the TCM receives a manual mode shift down signal from the unified meter and A/C amp.
