NAVIGATION
1. The navigation screen will be shown, and items “Display Longi-
tude & Latitude ”, “Speed Calibration ”, “Angle Adjustment ” and
“Initialize Location ” will become selective.
2. Select each switch on “NAVIGATION” screen to display the rele- vant diagnosis screen.
GPS RTC
malfunction Clock IC in GPS substrate is malfunctioning.

Correct time may not be displayed.

After the power is turned on, the system
always takes some time until GPS positioning
becomes possible. (The GPS receiver starts
positioning without re-collecting the whole sat-
ellite information when it judged the data
stored in the receiver is correct.)

Correct time of error occurrence may not be
stored in the ″
Error History″.

Perform self-diagnosis.

When the NAVI control unit is judged normal by self-diagnosis,
the symptom may be intermittent, caused by strong radio inter-
ference.
GPS antenna
disconnected Malfunctioning connection between GPS substrate in NAVI control
unit and GPS antenna.

Navigation location detection performance
has deteriorated.
(Location correction using GPS is not per-
formed.)

GPS receiving status remains gray.

Perform self-diagnosis.

When connection between NAVI control unit and GPS antenna
is judged normal by self-diagnosis, the symptom may be inter-
mittent, caused by impact or vibration.
Low voltage
of GPS The power voltage supplied to the GPS circuit board has
decreased.

Navigation location detection performance
has deteriorated.
(Location correction using GPS is not per-
formed.)

GPS receiving status remains gray.

Perform self-diagnosis.

When connection between NAVI control unit and GPS antenna
is judged normal by self-diagnosis, the symptom may be inter-
mittent, caused by impact or vibration.

Dedicated map DVD-ROM is in the system, but the data cannot be
read.

The map of a particular location cannot be dis-
played.

Specific guidance information cannot be dis-
played.

System has been affected by vibration.

Is map DVD-ROM damaged, warped, or dirty?
–If damaged or warped, the map DVD-ROM is malfunctioning.
–If dirty, wipe the DVD-ROM clean with a soft cloth.

Perform self-diagnosis.

When NAVI control unit is judged normal by self-diagnosis, the
symptom is judged intermittent, caused by vibration.

SQUEAK AND RATTLE TROUBLE DIAGNOSESPFP:00000
Work FlowEIS00626
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-10, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.

Creak —(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.

Rattle —(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

Tick —(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

Thump —(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.

Buzz —(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

Weather conditions, especially humidity and temperature, may have a great effect on noise level.

ADJUSTMENT
1. Loosen the stop lamp switch and ASCD switch by turning 45° counterclockwise.
2. Loosen lock nut on the input rod, then turn input rod to adjust the pedal to specified height. When finished adjusting, tighten lock
nut.
CAUTION:
Make sure that the screw portion of the end of input rod is
located inside the clevis.
3. With the pedal pulled up and held by hand, press the stop lamp switch and the ASCD switch in until threaded ends contact pedal
arm.
4. With the threaded ends of the stop lamp switch and ASCD switch contacting the pedal arm, turn the switches 45 ° clockwise
to lock in place.
CAUTION:
Make sure that the gap (C) between the rubber stops and
switch ends are within specification.
5. Check the pedal play. CAUTION:
Make sure that the stop lamp goes off when the pedal is
released.
6. Start the engine and check the height of the brake pedal when depressing it.Lock nut : 18.6 N·m (1.9 kg-m, 14 ft-lb)

BRAKE PIPING AND HOSEPFP:46210
Hydraulic CircuitEFS004W5
CAUTION:

All hoses and tubes must be free from excessive bending, twisting and pulling.

Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.

The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble
the parts. Replace applicable part with a new one, if necessary.

Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.

Do not bend or twist brake hose sharply, or strongly pull it.

When removing components, cover connections so that no dirt, dust, or other foreign matter gets
in.

Refill with new brake fluid. Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRICANTS" .

Do not reuse drained brake fluid.
Removal and Installation of Front Brake Hose EFS004W6
REMOVAL
