System Description
NKS000R1
A/T position is displayed in the segment display in the combination meter.
MANUAL MODE
●
Combination meter reads manual mode signal and shift-up/down signal from A/T device (manual mode
switch), and transmits the signals to TCM with CAN communication.
●
TCM processes manual mode signal and shift-up/down signal, and transmits A/T position indicator signal
and manual mode indicator signal to combination meter with CAN communication.
●
Combination meter indicates A/T gear position and manual mode indicator when receiving A/T position
indicator signal and manual mode indication signal.
NOT MANUAL MODE
●
Combination meter reads not manual mode signal from A/T device (manual mode switch), and transmits
the signals to TCM with CAN communication.
