SYSTEM DESCRIPTIONPFP:00000
System ComponentsEFS006LC
ABS FunctionEFS006LD

The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during
sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding
obstacles during emergency braking.

If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.

The electrical system can be diagnosed using CONSULT-II.

During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.

Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
the engine compartment. This is normal due to the self check operation.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
EBD FunctionEFS006LE

Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the brake fluid pressure
which results in reduced rear wheel slippage.

If the electrical system malfunctions, the Fail-Safe function is activated, the EBD and ABS become inoper-
ative, and the ABS warning lamp and brake warning lamp are turned on.

The electrical system can be diagnosed using CONSULT-II.

During EBD operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.

Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
the engine compartment. This is normal due to the self check operation.

NOTE:
The top portion of the figure (front side) shows view from LH side of vehicle. RH side is the mirror image.
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:

As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.

Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts and nuts to the specified
torques.

When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of
the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign
material and clean the mount.

When installing front wheel sensor, press rubber grommets of strut bracket and body all the way in until
they get locked, and be careful not to apply a twist to harness. Harness should not be twisted after instal-
lation. (Install it with harness paint mark on body side grommet facing front of vehicle, and the strut side
grommet facing outside of vehicle.)

When installing rear wheel sensor, press rubber grommets of suspension arm bracket and harness of side
member all the way in until they get locked, and be careful not to apply a twist to harness. Harness should
not be twisted after installation. (Aim the paint mark upward of vehicle.)

On-vehicle Inspection and Adjustment ECS00GVX
1. Check to see if the master cylinder rod end floats freely. It
should not be bound by the clutch pedal.
a. If the rod end is not free, check that the ASCD switch is not
applying pressure to the clutch pedal causing the rod end to
bind. To adjust, disconnect the ASCD switch electrical connector
and turn the ASCD switch.
b. Connect the ASCD switch electrical connector.
c. Verify that the master cylinder rod end floats freely. It should not
be bound by the clutch pedal.
d. If the rod end is still not free, remove the rod end and check for
deformation or damage. Leave the rod end removed for step 2.
2. Check the clutch pedal stroke for free range of movement.
a. With the master cylinder rod end removed, manually move the pedal up and down to determine if it moves
freely.
b. If any sticking is noted, replace the clutch pedal assembly. Re-verify that the master cylinder rod end floats
freely.
3. Adjust clutch interlock switch (1) position so that clearance
between clutch pedal (2) and thread end of clutch interlock
switch (1), with clutch pedal fully depressed, is within specifica-
tion (C).
Clearance C : 0.74 - 1.96 mm (0.0291 - 0.0772 in)

Air Bleeding ProcedureECS00FSY
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
CAUTION:

Carefully monitor fluid level in reservoir tank during bleeding operation.

Keep painted surface of body and other parts free of clutch fluid. If it spills, wipe up immediately
and wash the affected area with water.

First bleed the air from the operating cylinder air bleed
valve (1) and then from the bleed connector air bleed valve.
1. Connect a transparent vinyl tube and container to the air bleeder
valve on the clutch operating cylinder.
2. Fill reservoir tank with new clutch fluid.
3. Depress and release the clutch pedal slowly and fully 15 times
at an interval of 2 to 3 seconds.
4. With pedal depressed, continue the bleeding procedure.
5. Push the lock pin (1) of the bleeding connector (2) into the
locked position.
CAUTION:
Hold it to prevent releasing clutch tube from bleeding con-
nector (2) when fluid pressure is applied in the tube.
6. Slide clutch tube (1) in the direction of the arrow as shown, then
bleed the air from the tube.
7. Return clutch tube (1) and lock pin (2) to their original positions.
8. Release clutch pedal and wait for 5 seconds.
9. Repeat steps 2 to 8 until no bubbles are observed in the clutch
fluid.
