1. Rear Differential Fluid Pressure Sensor - Remove

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

3. Rear Differential Fluid Pressure Sensor - Test
NOTE: Check that the AWD system indicator does not come on. If it does, check for AWD with intelligent control system DTCs.
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 -30?30 kPa (-0.31?0.31 kgf/cm2, -4.4?4.4 psi), replace the rear differential fluid pressure sensor.
If the fluid pressure is within the range of -30?30 kPa (-0.31?0.31 kgf/cm2, -4.4?4.4 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 pressure test hose 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 434?599 kPa (4.43?6.11 kgf/cm2, 62.9?86.9 psi), replace the rear differential pump motor.
If the fluid pressure is within the range of 434?599 kPa (4.43?6.11 kgf/cm2, 62.9?86.9 psi), go to step 20.
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 434?599 kPa (4.43?6.11 kgf/cm2, 62.9?86.9 psi), replace the rear differential fluid pressure sensor.
If the fluid pressure is within the range of 434?599 kPa (4.43?6.11 kgf/cm2, 62.9?86.9 psi), rear differential fluid pressure sensor is OK and the test is complete.
