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
