SHIFT POSITION INDICATOR : System Description

INFOID:0000000003140162

Shift position is displayed in the information display 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 line.

• TCM processes manual mode signal and 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.

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 A/T shift position when receiving shift position signal.

OIL PRESSURE WARNING LAMP

• IPDM E/R inputs oil pressure switch signal from oil pressure switch, and transmits the signal to unified meter

and A/C amp. through BCM with CAN communication line.

• Unified meter and A/C amp. transmits oil pressure switch signal to combination meter with communication

line.

• Let the combination meter turn oil pressure warning lamp ON with received oil pressure switch signal.
