SYSTEM SHUT-DOWN

Scan tool display data does not agree with the actual
data when AWD-ECU deactivates the AWD control
function by the fail-safe function.

ACTUATOR TEST TABLE

M1274001100061

Scan tool can be used to forcibly activate the elec-
tronic control coupling and indicators (AWD indicator
and LOCK indicator) in the combination meter
according to the following items.
NOTE:

.

•

If AWD-ECU is deactivated by the fail-safe func-
tion, no actuator test can be performed.

•

As for the item No. 01, the chassis dynamometer
is used to check the AWD torque. A simple AWD
status check method, however, can be applied by
checking whether a tight corner braking phenom-
enon appears during driving.

CAUTION

When the item No. 01 is checked, the speed dif-
ference between front and rear wheels must be 5
km/h (3 mph) or lower. If the speed difference
exceeds 5 km/h (3mph), AWD-ECU changes from
the actuator test mode to the normal control
mode.

ON-VEHICLE SERVICE

CHECK OF ELECTRONIC CONTROL COUPLING

M1274005700140

SIMPLE OPERATION CHECK OF ELECTRONIC
CONTROL COUPLING

1. Raise the vehicle.
2. Mark the front and rear tires for easy identification of tire

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

P.36-9

.)

4. Pull the parking brake lever by two notches.

NOTE: Activating the parking brake slightly prevents the
drive force transferring to the rear wheels by a friction in the
electronic control coupling. If the following FWD mode is
checked without the parking brake activation, the drive force
is transferred to the rear wheels by a friction in the electronic
control coupling.

5. Start the engine, and move the shift lever into the D position.
6. Depress the accelerator pedal gradually, and maintain the

vehicle speed at approximately 10 km/h (6.0 mph).

7. Switch the drive mode selector to the FWD mode, and check

that the rear wheels are under FWD control (At this time, the
AWD/LOCK indicators in the combination meter do not
illuminate).

8. Stop the engine.
9. Start the engine again, and move the shift lever into the D

position.

10.Depress the accelerator pedal gradually, and maintain the

vehicle speed at approximately 10 km/h (6.0 mph).

CAUTION

The following checks in the AWD mode must be completed
within one minute in total to protect the AWD drive system
components and parking brake.
11.Switch the drive mode selector to the AWD mode, and

check that the rear wheels are rotating. (At this time, the
AWD indicator in the combination meter illuminates.)

After the above checks are completed, if the rear wheel rotation
satisfies the above conditions, it is judged that the electronic
control coupling operates correctly. If the rear wheel rotation
does not satisfy the above conditions, replace the electronic
control coupling. (Refer to

P.27C-97

.)
