Checking Fluid Level

On-vehicle Service
CHECKING FLUID LEVEL
1. Put vehicle on level ground and set selector lever in "P".
2. Make sure that no passengers nor any cargo is in vehicle, and that necessary equipment, such as spare tire, jack, on-board tools, are provided.
3. Confirm vehicle height selector switch is in "NORMAL".

4. With CONSULT
a. Connect CONSULT.
b. Start engine.
c. Check oil temperature using CONSULT data monitor.
Adjust oil temperature to 60 ± 4°C (140 ± 7.2°F)

5. Without CONSULT
a. Start engine, and warm up to raise active suspension fluid temperature about 60 °C (140°F).

6. Remove reservoir level gauge, and make sure that level is in the proper range.
^ Level gauge is a screw type, and level should be checked with the level gauge fitted securely.
^ If level is too low, add specified fluid (genuine "Fluid A-Active Suspension") through filler. Add fluid until actual level is aligned with proper UPPER range mark.

CAUTION:
^ Never use a non-specified brand of fluid.
^ If level is too high, suck out until proper level is reached; otherwise, fluid may overflow when releasing pressure.
^ If fluid is spilled on nearby parts, be sure to wipe clean.
^ If alarm lamp is ON Indicating insufficient oil quantity, erase the CONSULT self-diagnosis result data.

CHANGING FLUID

Every 96,000 km (60,000 miles) of operation, change fluid (genuine "Fluid A-Active Suspension").

1. Make sure vehicle is located in clean area and free from foreign particles. Raise vehicle and support with a rigid jack. Do not allow foreign particles to enter hydraulic system.
2. Open bypass valves of multivalve unit and pressure control unit as outlined under "RELIEVING PRESSURE, Service and Repair Repair of Component Parts".






3. Place a container under oil cooler to catch fluid. Disconnect rubber hose to multivalve unit (on lower side of oil cooler) and drain fluid into container.
4. Lower vehicle to ground. Reduce vehicle height and drain fluid from actuators as much as possible.
5. Raise vehicle again and reconnect rubber hose to its original position. Discard old hose clamp; replace it with a new one.
6. Close multivalve unit bypass valve and pressure control unit bypass valves.
7. Refer to "Repair of Component Parts" and "Work Procedures by Unit", then start with evacuating hydraulic lines.

CHECKING FLUID LEAKAGE

Oil leak check
Genuine "Fluid A-Active Suspension" is clear and light yellow-green when it is new. After use, it will turn to light yellow. After locating leaking point using table below as a guide, wipe away oil completely and check that oil leaks at the same point again. Do not confuse "Fluid A-Active Suspension" oil used in other systems.






Corrective measures for oil leaks
When repairing oil leaks, or when removing piping or hydraulic parts, refer to "Repair of Component Parts" and perform required work associated with leak repair if instructed.
1. Leaks at pipe connections






Refer to "Corrective measures for leaks at pipe connections".






2. Leaks at pressure detection ports

^ Make sure cock is tightened to specified torque.
^ Discard copper washer under blind bolt; replace it with a new one.
^ If leakage is still present, replace faulty detection port.
3. Leaks at air bleeder
^ Make sure that air bleeder is tightened to specified torque.






^ If retightening air bleeder does not eliminate leaks, replace affected unit with a new one.
4. Leaks at other parts, replace affected unit with a new one.
