4WD Control
U0122 Lost Communication With Vehicle Dynamics Control Module - General Information

Component Location





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

DTC U0122 is set if 4WD ECM can't receive any response signal from VDC.
