Rear Differential Clutch Test

Rear Differential Clutch Test (KA, KC Models AWD)

Test

1. HDS DLC - Connection





1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

2. Rear Differential Clutch Test





1. Block the front wheels (A), raise the left rear wheel, and support it with a safety stand (B) as shown.

2. Release the parking brake.





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, and retest. If the result is the same, replace the rear differential assembly.

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.

8. Check the condition of the rear differential fluid Rear Differential Fluid Inspection (AWD/4WD).

* If the fluid is dirty or burnt, replace the rear differential fluid.
* If the fluid is normal, go to step 9.

9. Make sure the rear differential fluid is at the proper level Rear Differential Fluid Inspection (AWD/4WD).

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

10. Check peripheral the rear differential for deformed or damaged.

* If the deformed or damaged peripheral the rear differential, replace the defective part.
* If the rear differential. is normal, go to step 11.

11. Do the rear differential pressure test with the HDS Rear Differential Pressure Test. If the Normal is displayed, go to step 12.

12. Do the rear differential fluid pressure sensor test Rear Differential Fluid Pressure Sensor Test. If the rear differential fluid pressure sensor is OK, replace the rear differential fluid, and retest. If the result is the same, replace the rear differential assembly.
