Honda HR-V: Rear Differential Clutch Test (AWD)
Test
1. HDS - Connect
2. Rear Differential Clutch - Test
- Block the front wheels (A), raise the left rear wheel, and support it
with a safety stand (B) as shown
- Release the parking brake.
- 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.
- Select the FUNCTIONAL TEST in the AWD WITH INTELLIGENT CONTROL
with the HDS
- Select the SOLENOID TEST in the FUNCTIONAL TEST with the HDS
- Do LEVEL 7 of the SOLENOID TEST with the HDS
- 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.
- 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.
- 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.
- 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.
- Do the rear differential pressure test with the HDS. If the Normal is
displayed, go to step 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.

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
- Remove the rear differential fluid pressure sensor.
- Reconnect the connector (A) to the rear differential fluid
pressure sensor (B).
3. Rear Differential Fluid Pressure Sensor - Test
- Turn the vehicle to the OFF (LOCK) mode
- Turn the vehicle to the ON mode
- Select the DATA LIST in the AWD WITH INTELLIGENT CONTROL with the
HDS
- 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.
- Turn the vehicle to the OFF (LOCK) mode
- Remove the oil pressure gauge from the A/T low pressure gauge set
- 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
- Place the end for the A/T pressure test hose into a drain pan (B)
- 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
- Turn the vehicle to the OFF (LOCK) mode
- Repeat step 9 again to assure the A/T low pressure gauge set is full of
fluid without
air bubbles.
- Attach the A/T low pressure gauge w/panel onto the end of the A/T
pressure test
hose
- Turn the vehicle to the ON mode
- Select the ADJUSTMENT in the AWD WITH INTELLIGENT CONTROL with
the HDS
- Select the AIR BLEEDING in the ADJUSTMENT with the HDS.NOTE : See the
HDS Help menu for specific instructions
- Select the FUNCTIONAL TEST in the AWD WITH INTELLIGENT CONTROL
with the HDS
- Select the SOLENOID TEST in the FUNCTIONAL TEST with the HDS
- Do LEVEL 7 of the SOLENOID TEST with the HDS.
- 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.
- 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.

Test
NOTE: Before doing the pressure test, check the following conditions.
Check that the AWD system indicator does not come on. If it does, check
for AWD with intelligent control system DTCs.
Che
1. Problem verification.
Turn the vehicle to the ON mode.
Does the AWD system indicator come on?
YES
Intermittent failure, the system is OK at this time.
NO
The failure is duplicated. Go to step 2.
