5D2-34 TRANSFER CASE - TOD DIAGNOSTIC TROUBLE CODE (DTC) 1714 EEPROM Checksum Fault Action Taken When the DTC Sets The TOD will illuminates 4WD CHECK indicator and DTC is stored in TOD. Circuit Description When the ignition is turned on the transfer case control unit (TOD) receives battery voltage and ignition volt- age and illuminates the 4WD CHECK and 4WD LOW indicators for 0.6 seconds. Then it starts self diagnosis to check itself. Diagnostic Aids • Check for poor connections, fuse and power supply wiring. • Check for ground condition. Conditions for Setting the DTC DTC 1714 is an indication of a potential internal transfer case control unit (TOD) malfunction.
It will set if any of following conditions is detected. • The calculated checksum for internal memory does not match the stored value. • The permanent memory storage area is malfunctioning. Test Description The number(s) below refer to step(s) on the diagnostic table. 2. This step checks the battery supply voltage. 4. This step checks the ground condition. 6. This step checks the connection status. SSANGYONG Y200 Step Action Value Yes No 1 Was the TOD Diagnostic System Check performed? - Go to Step 2 Go To “TOD Control Unit Diagnostic System Check” 2 1. Turn the ignition switch 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) • A5 (Battery supply) Does the voltage of the all circuits measure within the value specified? 11 ~ 14 V Go to Step 4 Go to Step 3 3 1. Check the fuse EF9 and voltage supply circuit. 2. Repair or replace any open or damaged circuit or fuse. Is the repair complete? - Go to Step 4 - 4 Connect a digital ohmmeter between each of the following TOD connector terminal and ground. • B9 (Ground). • B2 (Ground). Does the resistance of the all circuits measure within the value specified?
0 Ω Go to Step 6 Go to Step 5 5 Repair or replace any open or damaged circuit. Is the repair complete? - Go to Step 6 -
