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.

TCU
