Step 3 and 4. Visual inspection
As a preliminary step, be sure to perform visual check of
the items that support proper function of the 4WD control
system referring to “Visual Inspection: Motor-Shift Type
(Transfer with Shift Actuator)”.
Step 5. Trouble symptom confirmation
Check trouble symptoms based on information obtained
in “Step 1: Customer complaint analysis: Motor-Shift
Type (Transfer with Shift Actuator)” and “Step 2. DTC /
freeze frame data check, record and clearance: Motor-
Shift Type (Transfer with Shift Actuator)”.
Also, reconfirm DTC according to “DTC Confirmation
Procedure” described in each DTC flow.
Step 6 and 7. Rechecking and record of DTC and
freeze frame data
Refer to “DTC Check: Motor-Shift Type (Transfer with
Shift Actuator)” for checking procedure.
Step 8. 4WD control symptom diagnosis
Check the parts of the system suspected as a possible
cause referring to “4WD Control Symptom Diagnosis:
Motor-Shift Type (Transfer with Shift Actuator)”.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to
“applicable DTC flow”, locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
actuator, 4WD control module or other part and repair or
replace faulty parts.
Step 10. Check for intermittent problem

and then try shifting again.
1) Inspect shift operation from 4H to 4H-lock as follows.
a) Start engine.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following
conditions.
• Transfer shift position is 4H.
• Vehicle speed is less than 100 km/h (60 mph).
d) Turn transfer switch to “4H-lock” position.
e) Check that differential lock indicator blinks, and
then comes ON steady.
2) Inspect shift operation from 4H-lock to 4L-lock as
follows.
a) Stop vehicle completely with engine running.
b) Position front wheels straight ahead.
c) Confirm that vehicle is under following
conditions.
• Transfer shift position is 4H-lock.
• Transmission shift lever is at “N” position. (for
A/T model)
• Clutch pedal is depressed fully. (for M/T
model)
• Brake pedal is depressed.
d) Push and turn transfer switch to “4L-lock”
