ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT VEHICLE HEIGHT

NOTICE:

Perform the calibration on a level surface.
Perform the calibration with the vehicle empty.
Make sure that the wheels are on the ground and facing straight ahead.
Perform the calibration with the vehicle load completely on the suspension.

(a) Set the tire pressure to the specified value(s) (See page ).

(b) Bounce the vehicle to stabilize the suspension.

(c) Measure the distance from the ground to the top of the bumper and calculate the difference in the vehicle height between the left and right sides. Perform this procedure for both the front and rear wheels.

Height difference of left and right sides:

20 mm (0.787 in.) or less

HINT:

When the difference in vehicle height between the left and right sides is outside of the specification, perform air bleeding (See page ).

2. INSPECT FOR SUSPENSION FLUID LEAK

CAUTION:

Fluid is pumped into the system at a high pressure of approximately 3 MPa (30.6 kgf/cm2, 435 psi). If a fluid leak is discovered, immediately release the pressure and repair the fluid leak.

(a) Perform a driving test.

(b) Check for fluid leakage from the parts and connections shown in the illustration.
