if necessary.
3) Install PHV cable to PHV stay.
CAUTION:
If cable clamp (and clips) is damaged, replace
it with a new one.
4) Connect PHV cable with clips.

Avoid sharp bending of PHV cable as it may cause
breakage.
5) Install PHV cable onto cable bracket on engine.
6) Apply grease to the following points.
IHook portion of return spring
ICable end portion of lever
Grease:
SUNLIGHT 2 (Part No. 003602010)
7) Be sure to bleed air from the system.
CAUTION:
After replacing PHV cable or clutch cable with
new one, operate clutch pedal about 30 times
as a running-in operation prior to adjustment.
D: ADJUSTMENTS
Confirm stopping and starting performances by
activating hill holder on an uphill road of 3É or
higher inclination.
1) If vehicle does not stop;
Tighten adjusting nut of PHV cable.
2) If vehicle does not start properly;
ICase A Ð When hill holder is released later than
engagement of clutch pedal (Engine tends to
stall.):
Loosen adjusting nut gradually until smooth start-
ing is enabled.
ICase B Ð When hill holder is released earlier
than engagement of clutch pedal (Vehicle slips
down slightly.):
Tighten adjusting nut so that hill holder is released
later than engagement of clutch pedal (status in
Case A). Then make adjustment the same as in
Case A.NOTE:
Whenever turning adjusting nut, prevent PHV
cable from revolving as shown in Figure.

4) Within 0.5 seconds after the ABS warning light
goes out, depress the brake pedal and hold it
immediately after ignition switch is turned to ON.
CAUTION:
Do not depress the clutch pedal.
NOTE:
IWhen the ignition switch is set to on, the brake
pedal must not be depressed.
IEngine must not operate.
5) After completion of ABS sequence control, turn
ignition switch OFF.
2. OPERATIONAL GUIDELINES OF THE
ABS SEQUENCE CONTROL WITH
SELECT MONITOR
NOTE:
IIn the event of any trouble, the sequence con-
trol may not be operative. In such a case, activate
the sequence control, referring to ªOPERATIONAL
GUIDELINES OF THE ABS SEQUENCE CON-
TROL WITH DIAGNOSIS CONNECTORº. 4-4 [W15D1].>
IWhen the diagnosis terminal is connected to the
diagnosis connector, the sequence control will not
operate.
1) Connect select monitor to data link connector
beside driver's seat instrument panel lower cover.
2) Turn ignition switch ON.
3) Turn select monitor switch ON.
4) Put select monitor to {ABS/TCS} mode.
5) When {Function check sequence} is selected,
`ABS sequence control' will start.
6) The message `Press Brake Pedal Firmly' is dis-
played as follows:
(1) When using the brake tester, depress brake
pedal with braking force of 981 N (100 kg, 221
lb).
(2) When using the pressure gauge, depress
brake pedal so as to make the pressure gauge
indicate 3,432 kPa (35 kg/cm
2, 498 psi).
CAUTION:
Do not depress the clutch pedal.
7) When the message ªPress YESº is displayed,
press YES key.
8) Operation points will be displayed on select
monitor.
3. CONDITIONS FOR COMPLETION OF
ABS SEQUENCE CONTROL
When the following conditions develop, the ABS
sequence control stops and ABS operation is
returned to the normal control mode.
1) When the speed of at least one wheel reaches
10 km/h (6 MPH).
2) When terminal No. 3 or No. 6 are separated
from diagnosis terminals. (When select monitor is
not used.)
3) When the brake pedal is released during
sequence control and the braking lamp switch is
set to off.
4) When brake pedal is depressed after ignition
key is turned to ON, and before ABS warning light
goes out. (When select monitor is not used.)
5) When brake pedal is not depressed after igni-
tion key is turned to ON, and within 0.5 seconds
after ABS warning light goes out. (When select
monitor is not used.)

Trouble and possible cause Corrective action
In the case of the disc brake:

In the case of the drum brake:
(1) Excessively worn shoe ridge Replace the back plate.
(2) Lack of oil on the shoe ridge surface and anchor Add more grease.
2. Hill Holder
CAUTION:
IDescription in parentheses is a characteris-
tic of hill holder and does not indicate abnor-
mality.
Depressing force required for clutch pedal
equipped to hill holder specifications is 20 to
29 N (2 to 3 kg, 4 to 7 lb) larger than the con-
ventional specifications, which does not con-
stitute abnormality.IWhen vehicle cannot travel (brake cannot be
released) because return spring is broken,
remove adjusting nut, disconnect clutch and
PHV, and then return PHV lever to release the
brake. (Be sure to apply the parking brake
before starting this operation.)
IThe hill holder may not be activated on a
slope of an extremely small inclination.
Trouble and possible cause Corrective action
1. Counterforce of clutch pedal is too strong.
(1) PHV cable is damaged or does not operate properly. Repair or replace.
(2) Lever of PHV is defective. Replace entire PHV assembly.
(3) Clutch system is anomalous. Refer to ªClutch and pedal cable systemº.
2. Vehicle does not stop on uphill road of 3É or higher inclination.
(1) Front side of vehicle is lowered. Refer to ªSuspensionº.
(2) PHV cable is broken. Replace.
(3) Play of clutch is excessive. Adjust.
(4) PHV cable is elongated. Adjust.
(5) Sealing of PHV is poor. Replace entire PHV assembly.
3. Shock is felt when starting.
(1) Poor adjustment of starting performance: Adjust.
(2) When depressing the brake pedal strongly:(The stronger brake pedal depressing force, the later hill
holder releases.)
(3) When starting on flat road after stopping reverse move-
ment:(Because hill holder is activated.)
4. Vehicle slips down when starting.
(1) PHV cable is elongated. Adjust.
(2) Clutch facing is worn out. Adjust or replace.
(3) Bracket (cable) or stay (PHV) is deformed. Repair or replace.
5. Vehicle cannot start after stoppage.
(1) Return spring is fatigued or broken. Replace.
(2) PHV lever won't return. Replace entire PHV assembly.
(3) When intentionally depressing brake pedal strongly:[When the brake pedal is depressed by a force of 1,177 N
(120 kg, 265 lb) or more.]
6. Abnormal sound is generated upon releasing brake pedal when stopping.
(1) Rotor and pad matched with each other due to inadequate
depressing force to brake pedal.(Abnormal sound is not generated when depressing brake
pedal a little stronger.)
7. Abnormal sound is generated when operating clutch pedal.
(1) Grease is inadequate for the hook of return spring and
sliding portion of PHV cable end.Apply grease.
(2) When releasing after maintaining high fluid pressure: (Flowing sound of fluid when releasing high fluid pressure.)
(3) Clutch system is anomalous. Refer to ªClutch and pedal cable systemº.
