< SYMPTOM DIAGNOSIS >
SQUEAK AND RATTLE TROUBLE DIAGNOSES
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be dupl icated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine rpm or
load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

PLAY
THE TRUNK OPEN WARNING CONTIN UES DISPLAYING, OR DOES NOT
DISPLAY
DescriptionINFOID:0000000009461750
• The trunk ajar warning is displayed continuously even though the trunk lid is closed.
• The trunk ajar warning is not displayed even though the trunk lid is open.
Diagnosis ProcedureINFOID:0000000009461751
1.CHECK BCM INPUT SIGNAL
1. Connect the CONSULT.
2. Check the BCM input signals. Refer to DLK-126, "Component Function Check"
.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK COMBINATION METER INPUT SIGNAL
Select the Data Monitor for the METER/M &A and check the TRUNK/GLAS-H monitor value.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-82, "Removal and Installation".
NO >> Replace BCM. Refer to BCS-80, "Removal and Installation"
.
3.CHECK TRUNK ROOM LAMP SWITCH SIGNAL CIRCUIT
Check the trunk room lamp switch signal circuit. Refer to DLK-126, "Diagnosis Procedure"
.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair harness or connector.
4.CHECK TRUNK ROOM LAMP SWITCH
Check the room lamp switch. Refer to DLK-127, "Component Inspection"
.
Is the inspection result normal?
YES >> Replace combination meter. Refer to MWI-82, "Removal and Installation".
NO >> Replace trunk lid lock assembly. Refer to DLK-210, "TRUNK LAMP SWITCH AND TRUNK
RELEASE SOLENOID : Removal and Installation".

COMPASS
COMPASS : DescriptionINFOID:0000000009461756
COMPASS
• The electronic compass is highly protected from changes in most magnetic fields. However, some large
changes in magnetic fields can affect it. Some exampl es are (but not limited to): high tension power lines,
large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While
this does not happen very often, it is possible.
• During normal operation, the Compass Mirror will cont inuously update the compass calibration to adjust for
gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influ-
ences, the compass may appear to indicate false headings , become locked, or appear that it is unable to be
calibrated. If this occurs, perform the calibration procedure.
• If at any time the compass continually displays the inco rrect direction or the reading is erratic or locked, ver-
ify the correct zone variance.
Symptom Chart
Symptom Cause Solution / Reference
The compass display reads "C".
• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel bridges, subways, concentrations of
metal, car washes, etc.)
• Compass was calibrated incorrectly or
in the presence of a strong magnetic
field. Perform Calibration. Refer to
MWI-16,
"COMPASS : Description".
Compass shows the wrong direction.
Compass does not change direction ap-
pears "Locked".
Compass does not show all the directions,
one or more is missing.
The compass was calibrated but it "loses"
calibration.
On long trips the compass shows the
wrong direction. Perform Zone Variatio
n Setting if correct
reading is desired in that location. Refer to
MWI-16, "COMPASS : Description"

PEDAL STROKE
1. Operate parking brake pedal with a force of 196 N (20.0 kg-f, 44.1 lb-f), make sure pedal stroke is within
the specified number of notches. (Check it by listening and counting ratchet clicks.)
2. When brake warning lamp turns ON, check that the pedal stroke is within the specified number of notches. (Check it by listening to the clicks of the ratchet.)
INSPECT COMPONENTS
• Make sure that the mounting conditions (loosenes s, backlash, etc.) of each component are normal.
• Check the following:
- Device assembly for bend, damage and cracks. Replace if necessary.
- Cables and equalizer for wear and damage. Replace if necessary.
- Parking brake switch. Replace if necessary.
AdjustmentINFOID:0000000009462913
ADJUSTMENT
1. Remove rear wheel and tire using power tool. Refer to WT-55, "Adjustment".
2. Insert a deep socket wrench onto adjusting nut. Rotate adjusting nut to fully loosen cable, and then release parking brake pedal.
3. Secure both disc rotors to hubs using wheel nuts so as not to tilt the disc rotors.
4. Remove both adjuster hole plugs installed on the disc rotors. Turn the adjusters in direction (A) using a suitable tool or a flat-
bladed screwdriver as shown, until disc rotors are locked. Turn
the adjusters in the opposite direction by 5 or 6 notches after
locking.
5. Rotate the disc rotors to make sure that there is no drag. Install the adjuster hole plugs.
6. Adjust parking brake cable with the following procedure.
a. Rotate the adjusting nut to adjust parking brake pedal operating force to 490 N (50.0 kg-f, 110.2 lb-f) just before a full pedal
stroke of 201.65 mm (7.94 in).
CAUTION:
Do not reuse adjusting nut after removing it.
b. When replacing parking brake cable, operate parking brake pedal 10 or more times with a full stroke of 201.65 mm (7.94 in).
