DTC detecting condition Trouble area
2WD/4WD switch is changed of 4WD lock position, and then
vehicle is not changed for more than 5 seconds. • Coupling assembly
• Coupling assembly circuit
• 4WD control module
Step Action Yes No
1 Was “4WD control system check” performed? Go to Step 2. Go to “4WD Control
System Check”.
2 Coupling assembly circuit check
1) Disconnect coupling assembly connector “L102” with
ignition switch turned OFF.
2) Check for proper connection to “L102-1” and “L102-4”
terminals of coupling assembly connector.
3) If connection is OK, measure voltage between “L102-1”
terminal of coupling assembly connector and vehicle
body ground.
Is it 10 – 14 V?
Go to Step 3. Go to Step 6.
3 Coupling assembly ground circuit check
1) Measure resistance between “L102-4” terminal of
coupling assembly connector and vehicle body ground
with ignition switch turned OFF.
Is resistance below 5
Ω
?
Go to Step 4. Go to Step 5.
