SHIFT POSITION INDICATOR : System Description
INFOID:0000000001606627
Shift position is displayed in the information display LCD in the combination meter.
MANUAL MODE
When operated with A/T device
• Unified meter and A/C amp. inputs manual mode signal and manual mode shift-up/down signal from A/T
device (manual mode switch), and transmits the signals to TCM with CAN communication line.
• TCM processes manual mode signal and manual mode shift-up/down signal, and transmits manual mode
indicator signal and shift position signal to unified meter and A/C amp. with CAN communication line.
• Unified meter and A/C amp. transmits manual mode indicator signal and shift position signal to combination
meter with the communication line.
• Combination meter indicates A/T gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position signal.
When operated with paddle shifter
• Unified meter and A/C amp. inputs manual mode signal from A/T device (manual mode switch) or the paddle
shifter-up/down signal from the paddle shifter, and transmits the signals to TCM with CAN communication
line.
• TCM processes manual mode signal and paddle shifter-up/down signal, and transmits manual mode indica-
tor signal and shift position signal to unified meter and A/C amp. with CAN communication line.
• Unified meter and A/C amp. transmits manual mode indicator signal and shift position signal to combination
meter with the communication line.
• Combination meter indicates A/T gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position signal.
NOT MANUAL MODE
• Unified meter and A/C amp. inputs not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication line.
• TCM transmits shift position signal to unified meter and A/C amp. with CAN communication line.
• Unified meter and A/C amp. transmits shift position signal to combination meter with the communication line.
• Combination meter indicates shift position when receiving shift position signal.
