7AT RE7R01A M-Mode Switch

P1815 M-MODE SWITCH

Description

- The manual mode switch [manual mode select switch and manual mode position select switch (shift-up/shiftdown)] is installed in the A/T shift selector assembly. It transmits manual mode switch, shift up and shift down switch signals to unified meter and A/C amp. Then unified meter and A/C amp. transmits signals to
TCM via CAN communication.
- Manual mode select switch transmits manual mode switch signal or non-manual mode switch signal to unified meter and A/C amp. Then TCM receives signals from unified meter and A/C amp. via CAN communication.
- The manual mode position select switch (shift-up) transmits manual mode shift up signal to the unified meter and A/C amp. Then TCM receives signal from the unified meter and A/C amp. via CAN communication.
- The manual mode position select switch (shift-down) transmits manual mode shift down signal to the unified meter and A/C amp. Then TCM receives signal from the unified meter and A/C amp. via CAN communication.
- The TCM transmits manual mode indicator signal to the unified meter and A/C amp. via CAN communication line.
