5D2-32 TRANSFER CASE - TOD NO 4WD CHECK OR 4WD LOW INDICATOR WITH IGNITION SWITCH ON Circuit Description When the ignition switch turns to ON the transfer case control unit (TOD) illuminates 4WD CHECK and 4WD LOW indicator to check bulb operation and turns off after 0.6 seconds. Then TOD starts self-diagnosis and illuminate 4WD CHECK indicator when TOD detects any fault. Test Description The number(s) below refer to step(s) on the diagnostic table. 1. This step checks for the normal bulb operation. 5. This step checks voltage supply condition.
Diagnostic Aids If the both of the 4WD CHECK and 4WD LOW indicator were not illuminating there would be some problems with fuse, power supply line, improper connection of connector or transfer case control unit (TOD). If one of the indicators illuminates, the fuse and power supply line is good and the connector or TOD may be the cause of problems. SSANGYONG Y200 Step Action Value Yes No 1 Check the bulb operation when the ignition switch turns to ON. Does the only 4WD LOW indicator come on and goes after 0.6 seconds? - Go to Step 2 Go to Step 5 2 1. Turn the ignition switch to OFF. 2. Disconnect 18-pin connector from the transfer case control unit (TOD). 3.
Using test lamp check the continuity between terminal B2 of TOD and ground. Does the test lamp come on? - Go to Step 3 Go to Step 4 3 1. Turn the ignition OFF. 2. Check the pin or terminals for damage or improper connection. 3. Reconnect all the connectors. 4. Turn the ignition ON. Do the two indicators come on go after 0.6 seconds? - System OK Go to Step 7 4 Repair or replace of following components: • 4WD CHECK indicator bulb. • Open circuit between terminal A12 of cluster and terminal B2 of TOD connector. Is the repair complete? - System OK Go to Step 7 5 1. Check the fuse F2 and indicator bulbs. 2. Check the continuity for following terminals:
• Fuse F2 to B2 (TOD) • A2 (Cluster) to B2 (TOD) • B15 (Cluster) to B9 (TOD) Are there any problems? - Go to Step 6 Go to Step 7 6 Repair open circuit or replace damaged parts. Is the repair complete? - System OK Go to Step 7 7 Replace the TOD. Is the repair complete? - System OK -
