ISOLATION MODE (PRESSURE MAINTAIN)
If the information from the wheel speed sensors indicate excessive wheel deceleration (imminent lockup), the first step
in the antilock sequence is to isolate the brake pressure being applied by the driver. The EBCM sends a voltage to the
coil to energize and close the isolation valves by pulling down on the armature. This prevents any additional fluid pres-
sure applied by the driver from reaching the wheel. Though each channel of the 4-channel system can operate inde-
pendently, once any front channel (brake) sees excessive deceleration, both front isolation valves are energized and
close thus, with the isolation valves closed, further unnecessary increases in the brake pressure will be prohibited.

DUMP MODE (PRESSURE DECREASE)
Once the pressure is isolated, it must be reduced to get the wheels rolling once again. This is accomplished by dump-
ing a portion of the brake fluid pressure into a low pressure accumulator (LPA).
The EBCM energizes the dump cartage coil(s) to open the dump cartridge, allowing fluid from the wheels to be
dumped into the LPA. This done with very short activation pulses opening and closing the dump cartridge passageway.
Brake pressure is lowered at the wheel and allows the wheel to begin spinning again.
The fluid taken from the wheels forces the spring back and is stored in the LPA. A portion of the fluid also primes the
pump. The dump cartridges are operated independently to control the deceleration of the wheel.

CHECKING FLUID LEVEL
Check for a leak in the area of transaxle case and seal-
ing and then check fluid level and condition after remov-
ing oil level plug.
1. Operate the engine until it comes to normal operating
temperature(Coolant temperature : 80~90°C (176~
194°F)).
2. Stall the engine and raise the vehicle.
3. Remove the oil level plug and check the fluid level.
4. The fluid should slightly flow out from the oil level plug
hole.
5. If the level is low, add the recommended fluid through
the oil level plug hole until the fluid begins to run out.
6. If the fluid is contaminated or discolored, replace it
with the recommended fluid.
7. Reinstall the oil level plug and tighten it securely.

CHECKING TRANSAXLE NOISE
Many noises that appear to come from the transaxle
may actually originate with other sources such as tires,
road surfaces, wheel bearings, or engine and exhaust
system.
Identify the cause of any noise before attempting to re-
pair the clutch, the transaxle, or their related linkages.
To verify suspected transaxle noises,
1. Select a smooth, level asphalt road to reduce tyre
and resonant body noise.
2. Drive the vehicle far enough to warm up all the lubri-
cants thoroughly.
3. Record the speed and the gear range of the transaxle
when the noise occurs.
4. Check for noises with the vehicle stopped, but with
the engine running.
5. Determine if the noise occurs while the vehicle oper-
ates in.

Drive – Under a light acceleration or a heavy pull.

Float – Maintaining a constant speed with a light
throttle on a level road.

Coast – With the transaxle in gear and the throttle
partly or fully closed.

All of the above.
CHECKING BEARING NOISE
Differential Side Bearing Noise
Differential side bearing noise and wheel bearing noise
can be confused easily. Since side bearings are pre-
loaded, a differential side bearing noise should not di-
minish much when the differential/transaxle is run with
the wheels off the ground.
Wheel Bearing Noise
Wheel bearings produce a rough growl or grating sound
that will continue when the vehicle is coasting and the
transaxle is in NEUTRAL. Since wheel bearings are not
pre-loaded, a wheel bearing noise should diminish con-
siderably when the wheels are off the ground.
