Troubleshooting
Step
Action
Yes
No
1
Was “4WD control system check” performed?
Go to Step 2.
Go to “4WD Control
System Check”.
2
Coupling air temperature sensor circuit check
1) Disconnect connector from coupling air temperature
sensor with ignition switch turned OFF.
2) Check for proper connection to “BRN” and “ORN”
terminals of coupling air temperature sensor connector.
3) If connection is OK, measure voltage between “BRN”
terminal of coupling air temperature sensor connector
and vehicle body ground with ignition switch turned ON.
Is it 4 – 6 V?
Go to Step 3.
Go to Step 5.
3
Coupling assembly ground circuit check
1) Disconnect connector from 4WD control module with
ignition switch turned OFF.
2) Measure resistance between “ORN” terminal of coupling
air temperature sensor connector and “G26-24” terminal
of 4WD control module connector with ignition switch
turned OFF.
Is resistance below 5
Ω
?
Go to Step 4.
“ORN” wire is open or
high resistance.
4
Coupling air temperature sensor check
1) Check coupling air temperature sensor referring to
“Coupling Air Temperature Sensor Inspection”.
Is it in good condition?
Substitute a known-
good 4WD control
module and recheck.
Replace coupling air
temperature sensor.
5
Coupling assembly circuit check
1) Disconnect connector from 4WD control module with
ignition switch turned OFF.
2) Check for proper connection to “G26-25” and “G26-24”
terminals of 4WD control module connector.
3) If connection is OK, measure resistance between “G26-
25” terminal of 4WD control module connector and
vehicle body ground.
Is resistance below 5
Ω
?
“BRN” wire is open or
high resistance circuit.
Substitute a known-
good 4WD control
module and recheck.
