Component Tests and General Diagnostics

SH-AWD Function Test

Special Tools Required

- Adapter, torque wrench 070AJ-SJAA101

Direct Electromagnetic Clutch Test

NOTE:

- Check to make sure no DTCs are detected.

- The shift lever is in P.

- The SH-AWD control unit had been initialized.


1. With the ignition switch in LOCK (0), connect the HDS to the DLC (A) behind the driver's dashboard lower cover.





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

3. Check that the differential fluid temperature is over 68 °F (20 °C) with the HDS. If it is below 68 °F (20 °C), raise the temperature by driving the vehicle in circles or by constantly turning.

4. Raise the vehicle, and make sure it is securely supported Service and Repair.

5. Remove the rear wheels.

6. Install the torque wrench adapter on the rear wheel hub.






7. Connect the HDS to the DLC.

8. Do the direct electromagnetic clutch test with the HDS.

9. Install a torque wrench on the special tool as shown on the HDS. Write down the torque value while slowly rotating the rear hub with the torque wrench as shown. (Turn the hub no more than 90 degrees in 7 to 10 seconds).
NOTE: Use a torque wrench capable of measuring up to 80 kgf-m (580 lbf-ft) such as a commercially available Snap-on torque wrench TE352FUE.






10. Enter the torque value into the HDS, and wait for the test to finish.

- If the result shows the clutch driving force is normal, the clutch assembly is OK.

- If the result shows the clutch driving force is abnormal, replace the differential fluid, and retest. If the result still shows the clutch driving force is abnormal, replace the right and left differential side case Rear Differential Side Case Replacement.
