General Description

CAN communication is a parallel circuit to interchange information among each units. CAN communication can share much information with units more faster and more efficiently by using specified language. CAN-High line is twisted with CAN-Low line as a purpose in preventing from a noise. TCCU performs active control by sharing signals of engine RPM, APS, shift position, torque reduction.






DTC Description

This code related to communication line between TCU/PCM and TCCU is set when CAN signal from ECU can't received for more than 1 sec or ECU internal error occur.
