VDC/TCS/ABS Communication Line

VDC/TCS/ABS COMMUNICATION LINE
This CAN communication line is used to control the smooth engine operation during the ABS or TCS operation. Pulse signals are exchanged between ECM and ABS actuator and electric unit or ABS/TCS control unit.

Be sure to erase the malfunction information such as DTC not only in ABS actuator and electric unit or ABS/TCS control unit but also ECM after the ABS or ABS/TCS related repair.
