CHECKING THE ANTI-DIVE FUNCTION

1. Turn the ignition key to ON.
2. input a simulated vehicle-speed signal of 3 km/h (2 mph)
HARD ;g;
or more.
3. Select the AUTO or SOFT control mode.
4. With the brake pedal depressed (the stop lights ON), check
that the damping force characteristic level indicator lights
change to the HARD indication when the simulated
vehicle-speed input signal is suddenly decreased from 100
km/h (62 mph) or higher, and that there is air supply at
front and exhaust at the rear.

CHECKING THE ANTI-SQUAT FUNCTION

1. Turn the ignition key to ON.
2. Input a simulated vehicle-speed signal that is 3 km/h (2
HARD ;F;
mph) or higher and is less than 100 km/h (62 mph).
3. Select the AUTO or SOFT control mode.
4. Check that the damping force characteristic level indicator
lights change to the HARD indication when the accelerator
pedal is suddenly depressed, and that there is air exhaust at
the front and supply at the rear.

CHECKING THE VEHICLE-SPEED RESPONSE FUNCTION

1. Start the engine.
2. Input simulated vehicle-speed signals and check whether
or not there are changes of the damping force and of the
vehicle height (as shown in the diagram below) according'
to changes in the vehicle speed.
