Diagnostic Trouble Code (Dtc) 1722 - SSANGYONG Rexton Y200 Manual

5D2-42 TRANSFER CASE - TOD

DIAGNOSTIC TROUBLE CODE (DTC) 1722

Electromagnetic Clutch Short to Ground
Circuit Description
To control the distribution of the torque to front propeller
shaft, the transfer case control unit (TOD) sends a
signal to the electromagnetic clutch (EMC). Then the
clutch disc is compressed or released by the EMC.
Conditions for Setting the DTC
Even the TOD send signal for controlling the EMC, it
receives uncontrolled propeller shaft speed signal.
•
The wiring circuit to EMC is shorted to ground.
Action Taken When the DTC Sets
The TOD will illuminates 4WD CHECK indicator and
DTC is stored in TOD.
