2. Hill Holder
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“Clutch and pedal cable system”.
2. Vehicle does not stop on uphill road of 3°or higher inclination.
(1) Front side of vehicle is lowered. Refer to“Suspension”.
(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 movement: (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 slid-
ing 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“Clutch and pedal cable system”.
CAUTION:

Description in parentheses is a characteristic of hill holder and does not indicate abnormality.
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 conventional specifications, which does not constitute abnormality.

When 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 opera-
tion.)

The hill holder may not be activated on a slope of an extremely small inclination.

11. Compressor
Compressor is a swash plate type. When trouble occurs,
replace compressor as a single unit.
B4M0090
A: COMPRESSOR CLUTCH INSPECTION
Compressor clutch trouble is often caused by clutch slip-
page and noise. Check and take corrective measures, as
required.
1) Remove belt cover.
2) Check that clearance between drive plate and pulley
over the entire perimeter is within specifications.
Clearance:
0.3 — 0.6 mm (0.012 — 0.024 in)
B4M0091
3) Check that voltage applied to magnetic coil is at least
10.5 volts.
4) When noise is noted, check that it originates in either
compressor or pulley bearing.
B4M0760A
B: REMOVAL
1) Disconnect ground cable from battery.
2) Discharge refrigerant using refrigerant recovery system.

(1) Fully close low-pressure valve of manifold gauge.
(2) Connect low-pressure charging hose of manifold
gauge to low-pressure service valve.
(3) Open low-pressure manifold gauge valve slightly,
and slowly discharge refrigerant from system.
CAUTION:
Do not allow refrigerant to rush out. Otherwise, com-
pressor oil will be discharged along with refrigerant.

Process
No.Process name Job contents
9 WeldingUsing a heater gun and PP welding rod, weld the beveled spot while melting the rod and damaged
area.
G5M0167
NOTE:

Melt the sections indicated by hatched area.

Do not melt welding rod until it flows out, in order to provide strength.

Always keep the heater gun 1 to 2 cm (0.4 to 0.8 in) away from the welding spot.

Leave the welded spot unattended until it cools completely.
10 Sanding (II)Remove excess part of weld with a putty knife. If a drill or disc wheel is used instead of the knife,
operate it at a rate lower than 1,500 rpm and grind the excess part little by little. A higher rpm will
cause the PP substrate to melt from the heat.
G5M0168
Sand the welded spot smooth with #240 sand paper.
11 MaskingMask the black substrate section using masking tape.
Recommended masking tape: Nichiban No. 533 or equivalent
12 Cleaning/degreasing Completely clean the entire coated area, using solvent similar to that used in process No. 4.
13 Primer coatingApply a coat of primer to the repaired surface and its surrounding areas. Mask these areas, if neces-
sary.
Recommended primer: Mp/ 364 PP primer
NOTE:
Be sure to apply one coat of primer at a spraying pressure of 245 to 343 kPa (2.5 to 3.5 kg/cm
2,36
to 50 psi) with a spray gun.
14 Leave unattended.Leave the repaired area unattended at 20°C (68°F) for 10 to 15 minutes until primer is half-dry.
NOTE:
If dirt or dust comes in contact with the coated area, wipe it off with a cloth dampended with alcohol.
(Do not use thinner since the coated area tends to melt.)
15Primer surfacer
coatingApply a coat of primer surfacer to the repaired area two or three times at an interval of 3 to 5 min-
utes.
Recommended surfacer:
UPS 300 Flex primer

No. 303 UPS 300 Exclusive hardener

NPS 725 Exclusive reducer (thinner)

Mixing ratio:2:1(UPS 300: No. 303)

Viscosity: 12—14 sec/20°C (68°F)

Coated film thickness: 40—50µ
16 Drying Allow the coated surface to dry for 60 minutes at 20°C (68°F) [or 30 minutes at 60°C (140°F)].
17 Sanding (III) Sand the coated surface and its surrounding areas using #400 sand paper and water.

Condition Apparent cause/Correction
Door in fully closed/
open position1) Glass rides over weatherstrip lip when door is closed.
G5M0505(This condition increases wind/booming noise, leakage and/or
effort required to close door.)Improper up-down and in-out glass
alignments
Adjust glass for up-down and in-out
alignments (incl. rear sash, upper
stopper adjustment, etc.). If
necessary, correct glass tilt by
moving B channel regulator.
2) Edge of glass contacts retainer when door is fully closed.
G5M0506
Improper glass-to-center pillar
weatherstrip or excessive glass
contact to weatherstrip
Excessive adjusting in contact to
weatherstrip
Causes rear edge of glass to tilt
inboard closer to center pillar.
Adjust rear sash adjustment bolt to
reduce glass contact to
weatherstrip.
Raise or lower
window glass1) Considerable effort or time is required to operate regulator.
Standard operating effort:
Entire up-down travel except for point 5 mm (0.20 in)
below fully closed position:
29.4 N (3.0 kg, 6.6 lb)
Point 5 mm (0.20 in) below fully closed position:
44.1 N (4.5 kg, 9.9 lb)
G5M0507
Sliding resistance increased due to
high stabilizer-to-glass contact
pressure.
Reduce contact by mounting inner
stabilizer to inside of the vehicle.
High glass-to-windshield contact
pressure
Reduce contact using upper sash
adjustment bolt.
Unequal contact adjustment stroke
between front and rear sashes
Set to equal stroke.
Tilt of rear sash adjustment bolt
mounting bracket
Correct tilt of bracket so it is
parallel to inner panel.
