Component Location
General Description

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 is related to the EMC and is set If control harness has an short or short to ground.

If failure is detected TCCU prohibits the ITM control and vehicle is controlled with 2WD by intercepting EMC current.
