4WD Control
P1756 EMC Internal Error - General Information

Componet Location





General Description

ITCC(Intelligent Torque Control Coupling) 4WD :
Vehicle uses 2WD(2 wheel drive) for driving at normal speed, but sometimes it uses 4WD (4 wheel drive) accordign to driving condition. (cornering or acceleration)
EMC(Electric Magnetic Clutch) distributes proper torque to front wheel by controling amount of current inside EMC coil.
That time power pressing the multi plate clutch by apply cam is changed by a rate of EMC duty. after multi plate clutch start slip the force for acceletion at front/rear wheel is controlled at a range of 100:0 - 50 : 50.

DTC Description

This DTC code is related to the EMC and is set If control harness has an short to battery source.
If failure is detected "4WD-ECM" prohibits the "ITCC" control and vehicle is controlled with 2WD by intercepting EMC current.
