5. Identify the condition in which the noise occurs, and check the noise filter on the related part.
Condition in which noise occursNoise Source
Depressing the acceleration pedal increases the noise, and stopping the
engine stops the noise immediately.Generator
Noise occurs during A/C or the heater operation.Blower motor
Rapid acceleration while driving on an unpaved road or after the ignition
switch is turned on makes noise.Fuel pump
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes unusual noise.Horn
Quiet noise is heard while the engine is running, but stops with the engine.Ignition
Noise occurs synchronously with the turn signal flash.Flasher
Noise occurs during window washer operation.Washer
Noise occurs while the engine is running, and it continues even after the en-
gine stops.Engine coolant temperature sensor
Noise occurs during wiper operation.Wiper
Noise occurs when the brake pedal is depressed.Stop light switch
Others.Static electricity stored on the vehicle
Reference:
Make sure first that there is no noise from outside. Failing to do so makes the noise source detec-
tion difficult and leads to misdiagnosis.
The noise should be removed in descending order of loudness.
Tuning the radio so that no station is received wakes the noise more noticeable, making the rec-
ognition of the phenomenon easier.

Noise occurs
INSPECTION PROCEDURE
1 Check of speaker installation.
CHECK:
Check if each speaker is securely installed.
OK:
Each speaker is securely installed.
HINT:
The radio is equipped with a noise prevention system that blocks excessively loud noise. If such noise oc-
curs, check the all wiring is proper and that the antenna installation part ground and noise±prevention equip-
ment are installed.
Condition in which noise occursNoise type
Noise increases when the accelerator pedal is depressed, but stops when
the engine is stopped.Generator noise
Noise occurs during A/C or the heater operation.Blower motor noise
Noise occurs when the vehicle accelerates rapidly on an unpaved road or
after the ignition switch is turned on.Fuel pump noise
Noise occurs when the horn switch is pressed and released or when pressed
and held.Horn noise
Quiet noise occurs while the engine is running, but stops when the engine is
stopped.Ignition noise
Noise occurs synchronously with the blink of the turn signal.Flasher noise
Noise occurs during window washer operation.Washer noise
Noise occurs while the engine is running, and it continues even after the en-
gine is stopped.Water temperature sensor noise
Noise occurs during wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity stored on the vehicle
HINT:
Identify the condition under which the noise occurs, and check the noise filter on the related part.
First ensure that the noise is not coming from the outside. Failure to do so makes noise source detec-
tion difficult and may lead to a misdiagnosis.
Noise should be removed in descending order of loudness.
NG Install it properly.

first shift the transmission shift lever into the ºNº
position.
Do not operate the four wheel drive control switch
and the differential lock switch at the same time.

ON±VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
151.1 ± 165.1 mm (5.949 ± 6.500 in.)
NOTICE:
Do not adjust the pedal height. Doing so by changing the
push rod length of the brake booster will structurally
change the pedal ratio.
If the pedal height is incorrect, check that there is no damage
in brake pedal, brake pedal lever, brake pedal bracket and dash
panel.
Even if there is damage, there is no problem if the
reserve distance is within the standard value.
If necessary, replace them.
2. IF NECESSARY, ADJUST STOP LIGHT SWITCH
(a) Remove the front door scuff plate, cowl side trim, side
panel, lower finish panel and No. 2 heater to register duct
(See page BO±89).
(b) Loosen the stop light switch lock nut.
(c) Push the brake pedal in 5 ± 15 mm (0.20 ± 0.59 in.), turn
the stop light switch to lock the nut in the position where
the stop light goes off.
(d) Push the brake pedal in 5 ±15 mm (0.20 ± 0.59 in.), check
that the stop light lights up.
(e) Install the No. 2 heater to register duct, lower finish panel,
side panel, cowl side trim and front door scuff plate (See
page BO±89).
3. CHECK PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the second point of resis-
tance begins to be felt, then measure the distance as
shown in the illustration.
Pedal free play: 1 ± 6 mm (0.04 ± 0.24 in.)
HINT:
The free play to the first point of resistance is due to the play
between the clevis and pin. It is 1 ± 3 mm (0.04 ± 0.12 in.) at the
pedal.
If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance:
0.5 ± 2.4 mm (0.020 ± 0.095 in.)

ON±VEHICLE INSPECTION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly.
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is airtight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed. If there is no
change in the pedal reserve travel after holding the pedal
for 30 seconds, the booster is airtight.
