SHIFT POSITION INDICATOR

SHIFT POSITION INDICATOR : System Diagram

INFOID:0000000001606626

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.
