2. Disconnect the all-wheel drive solenoid connector.
3. Measure the resistance between terminals A and B of the all-wheel drive solenoid connector. If the measured resistance value is not within the standard (2.2-2.7 ohms at a rear final drive oil temperature of 20°C), replace the coupling.

4. Connect the 4WD solenoid connector.
5. Connect the negative battery terminal.
