3. Hold the left rear tire, and turn it counterclockwise continuously for more than one rotation.

If the wheel rotates, go to step 4.
If the wheel does not rotate, replace the rear differential fluid - Refer to: Rear Differential Fluid Inspection and Replacement (4WD) Rear Differential Fluid Inspection and Replacement (AWD) , and retest. If the result is the same, replace the rear differential assembly - Refer to: Rear Differential Removal and Installation (4WD)Rear Differential Removal and Installation (AWD) .

4. Select the FUNCTIONAL TEST in the REAL TIME AWD SYSTEM with the HDS

5. Select the SOLENOID TEST in the FUNCTIONAL TEST with the HDS

6. Do LEVEL 7 of the SOLENOID TEST with the HDS

7. Hold the left rear tire, and turn it counterclockwise continuously for more than one rotation.

If the wheel rotates, go to step 8.
If the wheel does not rotate, the system is OK at this time and the test is complete.

If the fluid is dirty or burnt, replace the rear differential fluid - Refer to: Rear Differential Fluid Inspection and Replacement (4WD) Rear Differential Fluid Inspection and Replacement (AWD) .
If the fluid is normal, go to step 9.

If the level is below the proper level, check for rear differential fluid leaks at the differential assembly and retest.
If the level is normal, go to step 10.

10.Visually check the rear differential for damage.

If any damage is found on the rear differential, replace the defective part as needed.
If the rear differential is normal, go to step 11.

11.Do the rear differential pressure test with the HDS - Refer to: Rear Differential Dual Pump System Function Test (4WD) Rear Differential Pressure Test (AWD) . If the Normal is displayed, go to step 12.
