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.
The 4WD ECM sets DTC U0100 if it doesn't receive APS signals from ECM.
