SYSTEM DESCRIPTIONPFP:00000
System DiagramEFS005TJ
FunctionsEFS005TK
ABS
lThe Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheels lock. Maneuverability is also
improved for avoiding obstacles.
lElectrical system diagnosis by CONSULT-II is available.
EBD
lElectronic Brake Distributor is a function that detects subtle slippages between the front and rear tyre dur-
ing braking, and it improves handling stability by electrically controlling the brake fluid pressure which
results in reduced rear tyre slippage.
lElectrical system diagnosis by CONSULT-II is available.
Operation That Is Not “System Error”EFS005TL
ABS
lWhen starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating noise
may be heard from engine room. This is a normal states of the operation check.
lDuring ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
lStopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionEFS005TM
ABS, EBD SYSTEM
In case of electrical malfunction with ABS, ABS warning lamp will turn on. In case of electrical incidents with
EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of following
conditions of Fail-Safe function.
1. For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
ABS system.
NOTE:
ABS self-diagnosis sound may be heard.That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
2. For EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.

WHEEL SENSORS
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:
lAs much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.
lTake 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.
lWhen 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.
lWhen installing wheel sensor, be sure to press rubber grommets in until they lock at locations shown
above in figure. When installed, harness must not be twisted.

On-Vehicle Inspection and AdjustmentECS00ICG
1. Make sure that clevis pin floats freely in the bore of clutch pedal.
It should not be bound by clevis or clutch pedal.
a. If clevis pin is not free, make sure that pedal stopper bolt or
ASCD clutch switch is not applying pressure to clutch pedal
causing clevis pin to bind. To adjust, loosen lock nut and turn
pedal stopper bolt or ASCD clutch switch.
b. Tighten lock nut.
c. Make sure that clevis pin floats in the bore of clutch pedal. It
should not be bound by clutch pedal.
d. If clevis pin is still not free, remove clevis pin and check for
deformation or damage. Replace clevis pin if necessary. Leave
the pin removed for step 2.
2. Check clutch pedal stroke for free range of movement.
a. With clevis pin removed, manually move clutch pedal up and down to determine if it moves freely.
b. If any sticking is found, replace related parts (clutch pedal bracket, assist spring, bushing etc.) Re-assem-
ble clutch pedal and again make sure that clevis pin floats freely in the bore of clutch pedal.
3. Adjust clearance “C” while depressing clutch pedal fully. (With
clutch interlock switch)
4. Check clutch hydraulic and system components (clutch master
cylinder, clutch operating cylinder, clutch withdrawal lever, clutch
release bearing, etc.) for sticking or binding.
a. If any sticking or binding is found, repair or replace related parts
as necessary.
b. If hydraulic system repair was necessary, bleed the clutch
hydraulic system. Refer toCL-8, "
Air Bleeding Procedure".
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.Clearance “C” : 0.1 - 1.0 mm (0.004 - 0.039 in)

COMPONENTS
REMOVAL
1. Disconnect clutch interlock switch and ASCD clutch switch (with ASCD) harness connectors.
2. Remove snap pin and clevis pin from clevis of clutch master cylinder.
3. Remove clutch pedal assembly mounting nuts and bolt, and then remove clutch pedal assembly from the
vehicle.
INSPECTION AFTER REMOVAL
lCheck clutch pedal for bend, damage, or a cracked weld. If bend, damage, or a cracked weld is found,
replace clutch pedal.
lCheck assist spring for settling. If settling is found, replace assist spring.
INSTALLATION
Installation is the reverse order of removal.
NOTE:
Tighten pedal stopper bolt lock nut or ASCD clutch switch lock nut to the specified torque after installing clutch
pedal assembly in vehicle and adjusting the pedal free play.
