Honda HR-V: Rear Differential Clutch Test (AWD)

Test

1. HDS - Connect

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 AWD WITH INTELLIGENT CONTROL 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.
   • 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.
   • 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. If the Normal is displayed, go to step 12.
12. Do the 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.

REAR DIFFERENTIAL FLUID PRESSURE SENSOR TEST (AWD)

Special Tools Required

A/T Low Pressure Gauge w/Panel 07406-0070301

A/T Pressure Adapter 07MAJPY40120

Pressure Gauge Adapter 07NAJP07010A

A/T Pressure Test Hose 07AAJPY4A100

Oil Pressure Hose 07ZAJ-S5A0200

Test

NOTE: Check that the real time AWD system indicator does not come on. If it does, check for real time AWD system DTC's

1. HDS - Connect

2. Rear Differential Fluid Pressure Sensor - Remove

1. Remove the rear differential fluid pressure sensor.
2. Reconnect the connector (A) to the rear differential fluid pressure sensor (B).

3. Rear Differential Fluid Pressure Sensor - Test

1. Turn the vehicle to the OFF (LOCK) mode
2. Turn the vehicle to the ON mode
3. Select the DATA LIST in the AWD WITH INTELLIGENT CONTROL with the HDS
4. Check the ACTUAL OIL PRESSURE OF THE OIL PRESSURE SENSOR FOR REAR DIFFERENTIAL in the DATA LIST with the HDS.
   • If the fluid pressure is not within -50-50 kPa (-0.51-0.51 kgf/cm2, -7.3-7.3 psi), replace the rear differential fluid pressure sensor.
   • If the fluid pressure is within the range of -50-50 kPa (-0.51-0.51 kgf/cm2, -7.3-7.3 psi), go to step 5.
5. Turn the vehicle to the OFF (LOCK) mode
6. Remove the oil pressure gauge from the A/T low pressure gauge set
7. Attach the A/T pressure test hose, the A/T pressure adapter, the pressure gauge adapter, and the oil pressure hose as shown, then Install the rear differential fluid pressure sensor (A) to the pressure gauge adapter
8. Place the end for the A/T pressure test hose into a drain pan (B)
9. Start the engine, the AWD pump will do a brief low pressure purge of the system, this will cause air and fluid to flow out of the A/T pressure test hose
10. Turn the vehicle to the OFF (LOCK) mode
11. Repeat step 9 again to assure the A/T low pressure gauge set is full of fluid without air bubbles.

12. Attach the A/T low pressure gauge w/panel onto the end of the A/T pressure test hose
13. Turn the vehicle to the ON mode
14. Select the ADJUSTMENT in the AWD WITH INTELLIGENT CONTROL with the HDS
15. Select the AIR BLEEDING in the ADJUSTMENT with the HDS.NOTE : See the HDS Help menu for specific instructions
16. Select the FUNCTIONAL TEST in the AWD WITH INTELLIGENT CONTROL with the HDS
17. Select the SOLENOID TEST in the FUNCTIONAL TEST with the HDS
18. Do LEVEL 7 of the SOLENOID TEST with the HDS.
19. Check the differential fluid pressure value of the oil pressure gauge.
    • If the fluid pressure is not within the range of 280-560 kPa (2.86-5.71 kgf/cm2, 40.6-81.2 psi), replace the rear differential pump motor.
    • If the fluid pressure is within the range of 280-560 kPa (2.86-5.71 kgf/cm2, 40.6-81.2 psi), go to step 21.
20. Check the ACTUAL OIL PRESSURE OF THE OIL PRESSURE SENSOR FOR REAR DIFFERENTIAL in the DATA LIST with the HDS.
    • If the fluid pressure is not within the range of 280- 560 kPa (2.86-5.71 kgf/cm2, 40.6-81.2 psi), replace the rear differential fluid pressure sensor.
    • If the fluid pressure is within the range of 280-560 kPa (2.86-5.71 kgf/cm2, 40.6-81.2 psi), rear differential fluid pressure sensor is OK, and the test is complete.

4. Rear Differential Fluid Pressure Sensor - Install

5. Rear Differential Fluid - Check
