A/T INDICATOR
System DescriptionINFOID:0000000001328470
A/T shift position is displayed in the s egment display in the combination meter.
MANUAL MODE
Unified meter and A/C amp. 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 manual mode indicator signal and shift 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 shift position indicator signal to
combination meter with the communication line.
Combination meter indicates shift gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position indicator signal.
NOT MANUAL MODE
Unified meter and A/C amp. reads not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication.
TCM transmits shift position indicator signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits shift position indicator signal to combination meter with the communi- cation line.
Combination meter indicates A/T shift position when receiving shift position indicator signal.
