BRAKE BOOSTERPFP:47200
On-Vehicle Inspection and ServiceEFS000CC
FUNCTION INSPECTION
With engine stopped, discharge stored vacuum by depressing brake
pedal several times at 5 second intervals. With brake pedal fully
depressed, start the engine. Confirm that clearance between brake
pedal and floor panel decreases when engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION

Run engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress brake pedal several
times with normal force to discharge the stored vacuum. Con-
firm that clearance between brake pedal and floor panel gradu-
ally increases as the brake pedal is depressed.

Run engine. Depress and hold brake pedal then stop engine.
Keep brake pedal depressed for 30 seconds or more and make
sure the pedal stroke does not change.

REMOVAL
CAUTION:

Be careful not to deform or bend brake piping while remov-
ing and installing brake booster.

Replace clevis pin if it is damaged.

Be careful not to damage brake booster stud bolt threads. If
brake booster is tilted or inclined during installation, dash
panel may damage the threads.

Be sure to install check valve in the correct orientation.
1. Remove vacuum piping from the brake booster.
2. Remove master cylinder.
3. Remove snap pin and clevis pin on the clevis of input rod. Remove input rod from the brake pedal.
4. Remove brake booster and brake pedal assembly mounting nuts.
5. Remove booster assembly from the engine compartment.

WHEEL SENSORS

WHEEL SENSORSPFP:47910
Removal and InstallationEFS004GR
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

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

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in the figure (2 at strut and 1 at body panel). When installed, harness must not be twisted.

CAUTION:

Do not drop or strike the G sensor, because it is sensitive to impact.

Do not use power tool, etc. Because G sensor is weak for the impact.
REMOVAL
1. Remove center console. Refer to IP-10, "INSTRUMENT PANEL
ASSEMBLY" .
2. Disconnect G sensor connector.
3. Remove mounting nuts and remove G sensor.
NOTE:
There is not need to detach the G sensor main body from a bracket.

PRECAUTIONS

CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS0027Z

The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.

Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.

The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to (J-
41995) pin-point refrigerant leaks.

For your safety and your customer’s satisfaction, read and follow all manufacture's operating instructions
and precautions prior to performing the work.

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector.

Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.

Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed.

Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

Do not use more than one refrigerant dye bottle (1/4 ounce / 7.4 cc) per A/C system.

Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system or A/C system damage may result.

The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.

COMPONENT INSPECTION
Ambient Sensor
After disconnecting ambient sensor connector E38, measure resis-
tance between terminals 2 and 1 at sensor side, using the table
below.
If NG, replace ambient sensor.
In-Vehicle Sensor CircuitEJS004YQ
COMPONENT DESCRIPTION
In-vehicle Sensor
The in-vehicle sensor is located on instrument driver lower panel. It
converts variations in temperature of compartment air drawn from
the aspirator into a resistance value. It is then input into the auto
amp.
Aspirator
The aspirator is located on front side of heater & cooling unit. It pro-
duces vacuum pressure due to air discharged from the heater &
cooling unit, continuously taking compartment air in the aspirator.
