A/T INDICATOR

A/T INDICATOR

PFP:24814

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.

●

TCM transmits A/T position indicator signal to combination meter with CAN communication.

●

Combination meter indicates A/T shift position when receiving A/T position indicator signal.
