Direct Electromagnetic Clutch Test
Direct Electromagnetic Clutch TestNOTE:
- No DTC was detected.
- The shift lever is in N.
- The SH-AWD control unit had been initialized.
- The tire pressures are at the specified value.
- Tire wear is the same between the left and right tires.
1. Check that the differential oil temperature is over 20°C (68°F) with the HDS. If it is below 20°C (68°F), raise the temperature by driving the vehicle in circles or by constantly turning.
2. Raise the vehicle, and make sure it is securely supported.
3. Remove the rear wheels.
4. Connect the HDS to the DLC.
5. Do the direct electromagnetic clutch test with the HDS.
6. Install the special tool on the rear wheel hub.
7. 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° in 7 to 10 seconds).
NOTE: Use a torque wrench capable of measuring up to 50 kg-m (360 ft. lbs.) such as a commercially available Snap-on torque wrench TE352FUE.
8. 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 oil, and retest. If the result still shows the clutch driving force is abnormal, replace the right and left clutch assemblies.
