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 prevents the drive force transferring
to the rear wheels by a friction in the
electronic control coupling. If the following
2WD 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.Execute the special test (item No. 4:
control off) (Refer to ) 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. 10.Switch the 4WD switch to
"4WD AUTO" position, and check that the rear wheels are
rotating. 11.Depress the accelerator pedal
gradually, and maintain the vehicle speed at approximately
10 km/h. 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.

Disconnect the electronic control
coupling solenoid connector, and measure the resistance
value between the connector terminals on the unit side. If
the measured resistance value is out of the standard value
range, replace the electronic control coupling. (Refer to .) Standard
value: 2.2 - 4.0 Ω
