TCU ▶
TCU is located under the driver's seat and controls the operations of transmission.
TCU receives the ignition voltage and has three connectors (16-pin, 12-pin, 20-pin).
TCU receives input signals from certain transmission-related sensors, gear select lever and inhibitor
switch. TCU also uses these signals when determining transmission operating strategy. TCU uses
PCAN to communicate with other units. And, TCU communicates with engine ECU, ESP unit, TCCU
and instrument cluster through CAN lines to control the gear shifting and to recognize the current gear
position.

This indicator shows the current position of the
gear.
In normal mode: P, R, N, D
Gear indication in “M” mode: 1, 2, 3, 4, 5, 6
Driving gear can be adjusted by operating the
tip switch after moving the gear select lever in
“M” position.

off the engine and depress the
brake pedal before the attempt. Tip Switch in “M” Position (Manual Gear Shift)
The shiftable gear can be adjusted by moving this switch to forward and rearward when the gear
select lever is in “M” position.
