Maximum 60 seconds

1. The test can be performed only when all the

following conditions are satisfied.

• Every wheel speed sensor input is 20 km/h or

less.

• No system malfunction is detected.

• The steering angle of steering wheel is within

±30° from the neutral position.

2. With the test, when any of the conditions below is

met, the forced activation will be cancelled.

• Any of the wheel speed sensors detects an input

of 20 km/h or more (excluding item No. 4 "Control
OFF").

• A system malfunction is detected.

• The forced activation time has elapsed.

• M.U.T.-III is removed.

• M.U.T.-III clear key is operated.

The sensor neutral position learned value initializa-
tion can be performed only when the vehicle is
stopped.

CHECK OF ELECTRONIC CONTROL
COUPLING

M1274005700225

SIMPLE OPERATION CHECK OF ELEC-
TRONIC CONTROL COUPLING

CAUTION

The following checks in the 4WD mode must be
completed within one minute in total to protect
the 4WD drive system components and parking
brake.
1. Raise the vehicle.

ACB05570 AB

Marking

2. Mark the front and rear tyres for easy

identification of tyre rotation.

3. Adjust the parking brake lever to the normal

conditions. (Refer to GROUP 36

− On-vehicle

Service, Parking Brake Lever Stroke Check and
Adjustment ).

4. Pull the parking brake lever by two notches. Then

start the engine.

NOTE: Activating the parking brake slightly pre-
vents the drive force transferring to the rear
wheels by a friction in the electronic control cou-
pling. If the following 2WD mode is checked with-
out the parking brake activation, the drive force is
transferred to the rear wheels by a friction in the
electronic control coupling.

5. Execute the special test (item No. 4: control off)

(Refer to

P.27C-48

) to switch the drive mode into

2WD forcibly.

6. Move the shift lever into the selector lever into D

position.

7. Depress the accelerator pedal gradually, and

maintain the vehicle speed at approximately 10
km/h. (Make sure that the rear wheels do not
rotate).

8. Stop the engine.

9. Start the engine again, and move the shift lever

into the selector lever into D position.
