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. The operating duty of EMC is maintained at 100 : 0 (2WD) for guaranteeing stabilized driving force, accuracy of the control during inside ABS, FTCS, ESP control.






DTC Description

This code related to communication line between ECU (ESP) and TCCU is set when CAN signal from ECU can't received for more than 1 sec or ECU internal error occur. If failure is detected TCCU prohibits the ITM control. If failure is detected ITM-ECU prohibits the ITM control and cuts the current to control coil.
