7D1-56 TRANSFER CONTROL SYSTEM
Even after the correction step 1-2(*), the 4WD indicator still blinks at 2Hz when shifting
from 2H to 4H.
Step Action Yes No
1 Check the air pressure and wear
of all the tires. Is any trouble
noticed? After adjusting the air pressure
and repairing the worn tires, try
the correction step 1-2(*). Go to step 2.
2
Check the 4W D detection switch
on the transfer case, neutral
detection switch and each
harness. Is a trouble noticed? 4W D detection switch is open or
the harness failed.
The neutral detection switch is
closed or the harness GND is
shorted.
Replace or repair and then trace
this chart from the beginning. Go to step 3.
3
Is there continuity in the harness
between the transfer controller
and front axle actuator? Has a
body short or disconnection
been detected? Go to step 4.
Body short or disconnection of
the harness between the transfer
controller and front axle actuator.
After repairing, trace this chart
from the beginning.
4 Is trouble detected in the axle
detection harness between the
axle actuator and transfer
controller? Disconnected harness.
After repairing trace this chart
from the beginning. Malfunction of axle actuator.
Refer to the paragraph of the axle
disconnect.
After repairing, trace this chart
from the beginning.
*Before determining a trouble (Non-trouble mode)
Note:
Vehicles with manual hub and rigid hub don’t have axle actuator.
W hen the above-mentioned procedure is followed, check the harness between the axle dummy output terminal and
the axle switch input terminal of the transfer controller, instead of axle actuator.

ELECTRICAL-BODY AND CHASSIS 8A-177
HEADLIGHT ADJUSTMENT
Preparation
Place the vehicle with 1 person in driver seat on a level surface
and check to see if the inflation pressure of the tires is correct,
the lenses are clean, the battery is sufficiently charged, and
adjust to place vehicle by using the screen.
1. Set a vertical screen on a level surface.
2. Toward the screen
1from the bulb center mark of the
headlight, extend parallel lines to the floor. Mark point
A
and B on the screen at the intersection of parallel line and
the screen.
3. Draw vertical lines through point
A and B on the screen.


4. Keep the vehicle 2 1m apart from the screen 1.
5. Draw a horizontal line through point
A and Bon the screen
1.


6. Turn the headlight low beam on.
7. Adjust the CUTLINE 11.6 mm below the horizontal line
H.
8. Adjust the BENDING POINT to the vertical line
V.
NOTE:
Always adjust vertical adjustment first.
