A/T INDICATORPFP:24814
System DescriptionNKS003UV
A/T position is displayed in the dot matrix LCD in the combination meter.
MANUAL MODE

Unified meter and A/C amp. inputs 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 manual mode indicator sig-
nal and A/T position indicator signal to unified meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits manual mode indicator signal and A/T position indicator 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 A/T position indicator 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.

TCM transmits A/T position indicator signal to unified meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits A/T position indicator signal to combination meter with the commu-
nication line.

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