SQUEAK AND RATTLE TROUBLE DIAGNOSES

Most of these incidents can be repaired by adjusting, securing or insulatingthe item(s) or component(s) caus-
ing the noise.

SUNROOF/HEADLINING

Noises in the sunroof/headlining area can often be traced to one of the following:

1.

Sunroof lid, rail, linkage or seals making a rattle or light knockingnoise

2.

Sunvisor shaft shaking in the holder

3.

Front or rear windshield touching headlining and squeaking

Again, pressing on the components to stop the noise while duplicatingthe conditions can isolate most of these
incidents. Repairs usually consistof insulating with felt cloth tape.

SEATS

When isolating seat noise it's important to note the position the seatis in and the load placed on the seat when
the noise is present. These conditionsshould be duplicated 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 suspectedcomponents while duplicating the condi-
tions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
orapplying urethane tape to the contact area.

UNDERHOOD

Some interior noise may be caused by components under the hood or onthe engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1.

Any component mounted to the engine wall

2.

Components that pass through the engine wall

3.

Engine wall mounts and connectors

4.

Loose radiator mounting 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.

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

Supply power using jumper cables if battery is discharged.

2.

Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)

3.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

4.

Perform the necessary repair operation.

5.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

6.

Perform self-diagnosis check of all control units using CONSULT-III.
