5D2-42 TRANSFER CASE - TOD DIAGNOSTIC TROUBLE CODE (DTC) 1722 Electromagnetic Clutch Short to Ground Diagnostic Aids • Check for poor connections of the circuit. • Check for EMC. 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. Test Description The number(s) below refer to step(s) on the diagnostic table. 2. This step checks poor connection or damage on the pin. 3. This step, along with step 4, checks the voltage supply condition. 5. This step checks the ground condition. 7.
This step checks the continuity of the wire and short to battery condition. 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. SSANGYONG Y200 Step Action Value Yes No 1 Was the TOD Diagnostic System Check performed? - Go to Step 2 Go to “TOD Diagnostic System Check” 2 1. Turn the ignition switch to OFF. 2.
Disconnect two connectors of the transfer case control unit (TOD) and white 7-pin connector, for propeller shaft speed sensor and clutch coil, located under the body. 3. Inspect the terminals for damage or improper connection. 4. Repair any damaged pins or terminals on the wiring harness and TOD. 5. Reconnect the connectors and make sure it is seated properly. 6. Connect a scan tool to the data link connector (DLC). 7. Turn the ignition ON. 8. Request the DTC with scan tool. Is the DTC still current? - Go to Step 3 System OK 3 1. Turn the ignition switch to OFF. 2. Disconnect the 12-pin connector from transfer case control unit (TOD). 3. Turn the ignition switch to ON. 4.
Connect a digital voltmeter between each of the following TOD connector terminal and ground. • A4 (Battery supply). • A11 (Battery supply). Does the voltage of the all circuits measure within the value specified? 11 ~ 14 V Go to Step 5 Go to Step 4 4 1. Check the fuse EF9, F10 and voltage supply circuit. 2. Repair or replace any open or damaged circuit or fuse. Is the repair complete? - Go to Step 5 -
